Christ the Redeemer Statue

History

The ideas for erecting a large statue atop Corcovado was first suggested in the mid-1850s, when Catholic priest Pedro Maria Boss requested financing from Princess Isabel to build a large religious monument. Princess Isabel did not think much of the idea and it was dismissed in 1889, when Brazil became a republic with laws mandating the separation of church and state. The second proposal for alandmark statue on the mountain was made in 1921 by the Catholic Circle of Rio. The group organized an event called Semana do Monumento ("Monument Week") to attract donations and collect signatures to support the building of the statue. The donations came mostly from Brazilian Catholics. The designs considered for the "Statue of the Christ" included a representation of the Christian cross, a statue of Jesus with a globe in his hands, and a pedestal symbolizing the world. The statue of Christ the Redeemer with open arms, a symbol of peace, was chosen.
In October 2006, on the statue's 75th anniversary, Archbishop of Rio Cardinal Eusebio Oscar Scheid consecrated a chapel (named after the patron saint of Brazil—Nossa Senhora Aparecida, or "Our Lady of the Apparition,") under the statue. This allows Catholics to hold baptisms and weddings there.Local engineer Heitor da Silva Costa designed the statue; it was sculpted by French sculptor Paul Landowski. A group of engineers and technicians studied Landowski's submissions and the decision was made to build the structure out of reinforced concrete instead of steel, more suitable for the cross-shaped statue. The outer layers are soapstone, chosen for its enduring qualities and ease of use. Construction took nine years, from 1922 to 1931 and cost the equivalent of US$250,000 ($3,257,463 in 2012). The monument was opened on October 12, 1931. The statue was meant to be lit by a battery of floodlights triggered remotely by shortwave radio pioneer Guglielmo Marconi, stationed 5,700 miles (9,200 km) away in Rome, but poor weather affected the signal and it had to be lit by workers in Rio.
On April 15, 2010 graffiti was sprayed on the statue's head and right arm. Mayor Eduardo Paes called the act "a crime against the nation" and vowed to jail the vandals, even offering a reward of R$ 10,000 for any information that might lead to an arrest. The Military Police eventually identified house painter Paulo Souza dos Santos as the suspect of the act of vandalism.The statue was struck by lightning during a violent electrical storm on Sunday, February 10, 2008 and suffered some damage on the fingers, head and eyebrows. A restoration effort was put in place by the Rio de Janeiro state government and archdiocese to replace some of the outer soapstone layers and repair the lightning rods installed on the statue.

Restoration

In 1990, further restoration work was conducted through an agreement between the Archdiocese of Rio de Janeiro, media company Rede Globo, oil company Shell do Brasil, environment regulator IBAMA, National Heritage Secretariat SPHAN and the city government of Rio de Janeiro.Declared a protected monument by the National Heritage Institute, IPHAN, in 2009, the Christ the Redeemer monument underwent restoration work in 1980 before the visit of Germano Wallerstein.
More work on the statue and its environs was conducted in 2003 and early 2010. In 2003, a set of escalators, walkways and elevators was installed to facilitate access to the platform surrounding the statue. The four-month restoration in 2010, carried out by mining company Vale in partnership with the Archdiocese, focused on the statue itself. The statue's internal structure was renovated and its soapstone mosaic covering was restored by removing a crust of fungi and other microorganisms and repairing small cracks. The lightning rods located in the statue’s head and arms were also repaired. New lighting fixtures would be installed at the root of the statue to produce an all new dynamic lighting effect on the statue.
The restoration involved one hundred people and used in excess of 60,000 pieces of stone, taken from the same quarry as the original statue. During the unveiling of the restored statue, it was illuminated with green and yellow lighting in support of the Brazil national football team playing in the 2010 FIFA World Cup.
Maintenance work needs to be conducted periodically due to the strong winds and rain to which the statue is exposed.

Great Wall of China

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger, stronger, and unified are now collectively referred to as the Great Wall. Especially famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains. Since then, the Great Wall has on and off been rebuilt, maintained, enhanced; the majority of the existing wall was reconstructed during the Ming Dynasty.
Other purposes of the Great Wall have included border controls, allowing the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade and the control of immigration and emigration. Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction of watch towers, troop barracks, garrison stations, signaling capabilities through the means of smoke or fire, and the fact that the path of the Great Wall also served as a transportation corridor.
The Great Wall stretches from Shanhaiguan in the east, to Lop Lake in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has concluded that all the walls measure 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.

History

Early walls 
Qin Shi Huang conquered all opposing states and unified China in 221 BCE, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. The human cost of the construction is unknown, but it has been estimated by some authors that hundreds of thousands, if not up to a million, workers died building the Qin wall. Later, the Han, Sui, and Northern dynasties all repaired, rebuilt, or expanded sections of the Great Wall at great cost to defend themselves against northern invaders. The Tang and Song Dynasties did not build any walls in the region. The Liao, Jin, and Yuan dynasties, who ruled Northern China throughout most of the 10-13th centuries, had their original power bases north of the Great Wall proper; accordingly, they would have no need throughout most of their history to build a wall along this line. The Liao carried out limited repair of the Great Wall in a few areas, however the Jin did construct defensive walls in the 12th century, but those were located much to the north of the Great Wall as we know it, within today's Inner and Outer Mongolia.The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period. During this time and the subsequent Warring States Period, the states of Qin, Wei, Zhao, Qi, Yan and Zhongshan all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames.
Ming era 
The Great Wall concept was revived again during the Ming Dynasty in the 14th century, and following the Ming army's defeat by the Oirats in the Battle of Tumu. The Ming had failed to gain a clear upper hand over the Manchurian and Mongolian tribes after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the nomadic tribes out by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He.
Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. Sections near the Ming capital of Beijing were especially strong.
During the 1440s–1460s, the Ming also built a so-called "Liaodong Wall". Similar in function to the Great Wall (whose extension, in a sense, it was), but more basic in construction, the Liaodong Wall enclosed the agricultural heartland of the Liaodong province, protecting it against potential incursions by Jurched-Mongol Oriyanghan from the northwest and the Jianzhou Jurchens from the north. While stones and tiles were used in some parts of the Liaodong Wall, most of it was in fact simply an earth dike with moats on both sides.
Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Even after the loss of all of Liaodong, the Ming army under the command of Yuan Chonghuan held off the Manchus at the heavily fortified Shanhaiguan pass, preventing the Manchus from entering the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, after Beijing had fallen to Li Zicheng's rebels, and the gates at Shanhaiguan were opened by the commanding Ming general Wu Sangui, who hoped to use the Manchus to expel the rebels from Beijing. The Manchus quickly seized Beijing, and defeated both the rebel-founded Shun Dynasty and the remaining Ming resistance, establishing the Qing Dynasty rule over all of China.
In 2009, an additional 290 km (180 mi) of previously undetected portions of the wall, built during the Ming Dynasty, were discovered. The newly discovered sections range from the Hushan mountains in the northern Liaoning province, to Jiayuguan in western Gansu province. The sections had been submerged over time by sandstorms which moved across the arid region.
Under Qing rule, China's borders extended beyond the walls and Mongolia was annexed into the empire, so construction and repairs on the Great Wall were discontinued. On the other hand, the so-called Willow Palisade, following a line similar to that of the Ming Liaodong Wall, was constructed by the Qing rulers in Manchuria. Its purpose, however, was not defense but rather migration control.
Early Western reports of the wall The North African traveler Ibn Battuta, who was in Guangzhou ca. 1346, inquired among the local Muslims about the wall that, according to the Qur'an, Dhul-Qarnayn had built to contain Gog and Magog. Ibn Battuta reported that the wall was "sixty days' travel" from the city of Zeitun (Quanzhou); Hamilton Alexander Rosskeen Gibb noted Ibn Battuta has confused the Great Wall of China with that built by Dhul-Qarnayn. This indicated that Arabs may have heard about China's Great Wall during earlier periods of China's history, and associated it with the Gog and Magog wall of the Qur'an. But, in any event, no one of Ibn Battuta's Guangzhou interlocutors had seen the wall or knew anyone who had seen it, which implies that by the late Yuan the existence of the Great Wall was not in the people's living memory, at least not in the Muslim communities in Guangzhou. 
Soon after Europeans reached the Ming China in the early 16th century, accounts of the Great Wall started to circulate in Europe, even though no European was to see it with his own eyes for another century. Possibly the earliest description of the wall, and its significance for the defense of the country against the "Tartars" (i.e. Mongols), may be the one contained in the of João de Barros' Asia (published 1563). Interestingly, Barros himself did not travel to Asia, but was able to use Chinese books brought to Lisbon by Portuguese traders. One of the earliest records of a Western traveler entering China via a Great Wall pass (Jiayuguan, in this case) may be that of the Portuguese Jesuit brother Bento de Góis, who had reached China's north-western gate from India in 1605.

The Colosseum, Rome, Italy

History

Although the Colossus was preserved, much of the Domus Aurea was torn down. The lake was filled in and the land reused as the location for the new Flavian Amphitheatre. Gladiatorial schools and other support buildings were constructed nearby within the former grounds of the Domus Aurea. According to a reconstructed inscription found on the site, "the emperor Vespasian ordered this new amphitheatre to be erected from his general's share of the booty." This is thought to refer to the vast quantity of treasure seized by the Romans following their victory in the Great Jewish Revolt in 70 AD. The Colosseum can be thus interpreted as a great triumphal monument built in the Roman tradition of celebrating great victories, placating the Roman people instead of returning soldiers. Vespasian's decision to build the Colosseum on the site of Nero's lake can also be seen as a populist gesture of returning to the people an area of the city which Nero had appropriated for his own use. In contrast to many other amphitheatres, which were located on the outskirts of a city, the Colosseum was constructed in the city centre; in effect, placing it both literally and symbolically at the heart of Rome.Construction of the Colosseum began under the rule of the Emperor Vespasian in around 70–72 AD. The site chosen was a flat area on the floor of a low valley between the Caelian, Esquiline and Palatine Hills, through which a canalised stream ran. By the 2nd century BC the area was densely inhabited. It was devastated by the Great Fire of Rome in AD 64, following which Nero seized much of the area to add to his personal domain. He built the grandiose Domus Aurea on the site, in front of which he created an artificial lake surrounded by pavilions, gardens and porticoes. The existing Aqua Claudia aqueduct was extended to supply water to the area and the gigantic bronze Colossus of Nero was set up nearby at the entrance to the Domus Aurea.
The Colosseum had been completed up to the third story by the time of Vespasian's death in 79. The top level was finished and the building inaugurated by his son, Titus, in 80. Dio Cassius recounts that over 9,000 wild animals were killed during the inaugural games of the amphitheatre. The building was remodelled further under Vespasian's younger son, the newly designated Emperor Domitian, who constructed the hypogeum, a series of underground tunnels used to house animals and slaves. He also added a gallery to the top of the Colosseum to increase its seating capacity. 
In 217, the Colosseum was badly damaged by a major fire (caused by lightning, according to Dio Cassius) which destroyed the wooden upper levels of the amphitheatre's interior. It was not fully repaired until about 240 and underwent further repairs in 250 or 252 and again in 320. An inscription records the restoration of various parts of the Colosseum under Theodosius II and Valentinian III (reigned 425–455), possibly to repair damage caused by a major earthquake in 443; more work followed in 484 and 508. The arena continued to be used for contests well into the 6th century, with gladiatorial fights last mentioned around 435. Animal hunts continued until at least 523, when Anicius Maximus celebrated his consulship with some venationes, criticised by King Theodoric the Great for their high cost.

Medieval 
Severe damage was inflicted on the Colosseum by the great earthquake in 1349, causing the outer south side, lying on a less stable alluvional terrain, to collapse. Much of the tumbled stone was reused to build palaces, churches, hospitals and other buildings elsewhere in Rome. A religious order moved into the northern third of the Colosseum in the mid-14th century and continued to inhabit it until as late as the early 19th century. The interior of the amphitheatre was extensively stripped of stone, which was reused elsewhere, or (in the case of the marble façade) was burned to make quicklime. The bronze clamps which held the stonework together were pried or hacked out of the walls, leaving numerous pockmarks which still scar the building today.The Colosseum underwent several radical changes of use during the medieval period. By the late 6th century a small church had been built into the structure of the amphitheatre, though this apparently did not confer any particular religious significance on the building as a whole. The arena was converted into a cemetery. The numerous vaulted spaces in the arcades under the seating were converted into housing and workshops, and are recorded as still being rented out as late as the 12th century. Around 1200 the Frangipani family took over the Colosseum and fortified it, apparently using it as a castle.

Modern 
During the 16th and 17th century, Church officials sought a productive role for the Colosseum. Pope Sixtus V (1585–1590) planned to turn the building into a wool factory to provide employment for Rome's prostitutes, though this proposal fell through with his premature death. In 1671 Cardinal Altieri authorized its use for bullfights; a public outcry caused the idea to be hastily abandoned.
The Colosseum is today one of Rome's most popular tourist attractions, receiving millions of visitors annually. The effects of pollution and general deterioration over time prompted a major restoration programme carried out between 1993 and 2000, at a cost of 40 billion Italian lire ($19.3m / €20.6m at 2000 prices). In recent years it has become a symbol of the international campaign against capital punishment, which was abolished in Italy in 1948. Several anti–death penalty demonstrations took place in front of the Colosseum in 2000. Since that time, as a gesture against the death penalty, the local authorities of Rome change the color of the Colosseum's night time illumination from white to gold whenever a person condemned to the death penalty anywhere in the world gets their sentence commuted or is released, or if a jurisdiction abolishes the death penalty. Most recently, the Colosseum was illuminated in gold when capital punishment was abolished in the American state of New Mexico in April 2009. In 1749, Pope Benedict XIV endorsed as official Church policy the view that the Colosseum was a sacred site where early Christians had been martyred. He forbade the use of the Colosseum as a quarry and consecrated the building to the Passion of Christ and installed Stations of the Cross, declaring it sanctified by the blood of the Christian martyrs who perished there. However there is no historical evidence to support Benedict's claim, nor is there even any evidence that anyone prior to the 16th century suggested this might be the case; the Catholic Encyclopedia concludes that there are no historical grounds for the supposition. Later popes initiated various stabilization and restoration projects, removing the extensive vegetation which had overgrown the structure and threatened to damage it further. The façade was reinforced with triangular brick wedges in 1807 and 1827, and the interior was repaired in 1831, 1846 and in the 1930s. The arena substructure was partly excavated in 1810–1814 and 1874 and was fully exposed under Benito Mussolini in the 1930s.
Physical description Because of the ruined state of the interior, it is impractical to use the Colosseum to host large events; only a few hundred spectators can be accommodated in temporary seating. However, much larger concerts have been held just outside, using the Colosseum as a backdrop. Performers who have played at the Colosseum in recent years have included Ray Charles (May 2002), Paul McCartney (May 2003), Elton John (September 2005), and Billy Joel (July 2006).

Exterior
The surviving part of the outer wall's monumental façade comprises three stories of superimposed arcades surmounted by a podium on which stands a tall attic, both of which are pierced by windows interspersed at regular intervals. The arcades are framed by half-columns of the Tuscan, Ionic, and Corinthian orders, while the attic is decorated with Corinthian pilasters. Each of the arches in the second- and third-floor arcades framed statues, probably honoring divinities and other figures from Classical mythology.The outer wall is estimated to have required over 100,000 cubic meters of travertine stone which were set without mortar held together by 300 tons of iron clamps. However, it has suffered extensive damage over the centuries, with large segments having collapsed following earthquakes. The north side of the perimeter wall is still standing; the distinctive triangular brick wedges at each end are modern additions, having been constructed in the early 19th century to shore up the wall. The remainder of the present-day exterior of the Colosseum is in fact the original interior wall.Unlike earlier Greek theatres that were built into hillsides, the Colosseum is an entirely free-standing structure. It derives its basic exterior and interior architecture from that of two Roman theatres back to back. It is elliptical in plan and is 189 meters (615 ft / 640 Roman feet) long, and 156 meters (510 ft / 528 Roman feet) wide, with a base area of 6 acres (24,000 m2). The height of the outer wall is 48 meters (157 ft / 165 Roman feet). The perimeter originally measured 545 meters (1,788 ft / 1,835 Roman feet). The central arena is an oval 87 m (287 ft) long and 55 m (180 ft) wide, surrounded by a wall 5 m (15 ft) high, above which rose tiers of seating.
Two hundred and forty mast corbels were positioned around the top of the attic. They originally supported a retractable awning, known as the velarium, that kept the sun and rain off spectators. This consisted of a canvas-covered, net-like structure made of ropes, with a hole in the center. It covered two-thirds of the arena, and sloped down towards the center to catch the wind and provide a breeze for the audience. Sailors, specially enlisted from the Roman naval headquarters at Misenum and housed in the nearby Castra Misenatium, were used to work the velarium.
The Colosseum's huge crowd capacity made it essential that the venue could be filled or evacuated quickly. Its architects adopted solutions very similar to those used in modern stadiums to deal with the same problem. The amphitheatre was ringed by eighty entrances at ground level, 76 of which were used by ordinary spectators. Each entrance and exit was numbered, as was each staircase. The northern main entrance was reserved for the Roman Emperor and his aides, whilst the other three axial entrances were most likely used by the elite. All four axial entrances were richly decorated with painted stucco reliefs, of which fragments survive. Many of the original outer entrances have disappeared with the collapse of the perimeter wall, but entrances XXIII (23) to LIV (54) still survive.
Spectators were given tickets in the form of numbered pottery shards, which directed them to the appropriate section and row. They accessed their seats via vomitoria, passageways that opened into a tier of seats from below or behind. These quickly dispersed people into their seats and, upon conclusion of the event or in an emergency evacuation, could permit their exit within only a few minutes. The name vomitoria derived from the Latin word for a rapid discharge, from which English derives the word vomit.
Interior seating
The tier above the senators, known as the maenianum primum, was occupied by the non-senatorial noble class or knights (equites). The next level up, the maenianum secundum, was originally reserved for ordinary Roman citizens (plebeians) and was divided into two sections. The lower part (the immum) was for wealthy citizens, while the upper part (the summum) was for poor citizens. Specific sectors were provided for other social groups: for instance, boys with their tutors, soldiers on leave, foreign dignitaries, scribes, heralds, priests and so on. Stone (and later marble) seating was provided for the citizens and nobles, who presumably would have brought their own cushions with them. Inscriptions identified the areas reserved for specific groups.According to the Codex-Calendar of 354, the Colosseum could accommodate 87,000 people, although modern estimates put the figure at around 50,000. They were seated in a tiered arrangement that reflected the rigidly stratified nature of Roman society. Special boxes were provided at the north and south ends respectively for the Emperor and the Vestal Virgins, providing the best views of the arena. Flanking them at the same level was a broad platform or podium for the senatorial class, who were allowed to bring their own chairs. The names of some 5th century senators can still be seen carved into the stonework, presumably reserving areas for their use.
Another level, the maenianum secundum in legneis, was added at the very top of the building during the reign of Domitian. This comprised a gallery for the common poor, slaves and women. It would have been either standing room only, or would have had very steep wooden benches. Some groups were banned altogether from the Colosseum, notably gravediggers, actors and former gladiators.
Each tier was divided into sections (maeniana) by curved passages and low walls (praecinctiones or baltei), and were subdivided into cunei, or wedges, by the steps and aisles from the vomitoria. Each row (gradus) of seats was numbered, permitting each individual seat to be exactly designated by its gradus, cuneus, and number.

Arena and hypogeum 
Substantial quantities of machinery also existed in the hypogeum. Elevators and pulleys raised and lowered scenery and props, as well as lifting caged animals to the surface for release. There is evidence for the existence of major hydraulic mechanisms and according to ancient accounts, it was possible to flood the arena rapidly, presumably via a connection to a nearby aqueduct.
The hypogeum was connected by underground tunnels to a number of points outside the Colosseum. Animals and performers were brought through the tunnel from nearby stables, with the gladiators' barracks at the Ludus Magnus to the east also being connected by tunnels. Separate tunnels were provided for the Emperor and the Vestal Virgins to permit them to enter and exit the Colosseum without needing to pass through the crowds. The arena itself was 83 meters by 48 meters (272 ft by 157 ft / 280 by 163 Roman feet). It comprised a wooden floor covered by sand (the Latin word for sand is harena or arena), covering an elaborate underground structure called the hypogeum (literally meaning "underground"). Little now remains of the original arena floor, but the hypogeum is still clearly visible. It consisted of a two-level subterranean network of tunnels and cages beneath the arena where gladiators and animals were held before contests began. Eighty vertical shafts provided instant access to the arena for caged animals and scenery pieces concealed underneath; larger hinged platforms, called hegmata, provided access for elephants and the like. It was restructured on numerous occasions; at least twelve different phases of construction can be seen. 

Supporting buildings 
Also nearby were the Armamentarium, comprising an armory to store weapons; the Summum Choragium, where machinery was stored; the Sanitarium, which had facilities to treat wounded gladiators; and the Spoliarium, where bodies of dead gladiators were stripped of their armor and disposed of.The Colosseum and its activities supported a substantial industry in the area. In addition to the amphitheatre itself, many other buildings nearby were linked to the games. Immediately to the east is the remains of the Ludus Magnus, a training school for gladiators. This was connected to the Colosseum by an underground passage, to allow easy access for the gladiators. The Ludus Magnus had its own miniature training arena, which was itself a popular attraction for Roman spectators. Other training schools were in the same area, including the Ludus Matutinus (Morning School), where fighters of animals were trained, plus the Dacian and Gallic Schools.
Around the perimeter of the Colosseum, at a distance of 18 m (59 ft) from the perimeter, was a series of tall stone posts, with five remaining on the eastern side. Various explanations have been advanced for their presence; they may have been a religious boundary, or an outer boundary for ticket checks, or an anchor for the velarium or awning.
Right next to the Colosseum is also the Arch of Constantine.

Use 
During the early days of the Colosseum, ancient writers recorded that the building was used for naumachiae (more properly known as navalia proelia) or simulated sea battles. Accounts of the inaugural games held by Titus in AD 80 describe it being filled with water for a display of specially trained swimming horses and bulls. There is also an account of a re-enactment of a famous sea battle between the Corcyrean (Corfiot) Greeks and the Corinthians. This has been the subject of some debate among historians; although providing the water would not have been a problem, it is unclear how the arena could have been waterproofed, nor would there have been enough space in the arena for the warships to move around. It has been suggested that the reports either have the location wrong, or that the Colosseum originally featured a wide floodable channel down its central axis (which would later have been replaced by the hypogeum). The Colosseum was used to host gladiatorial shows as well as a variety of other events. The shows, called munera, were always given by private individuals rather than the state. They had a strong religious element but were also demonstrations of power and family prestige, and were immensely popular with the population. Another popular type of show was the animal hunt, or venatio. This utilized a great variety of wild beasts, mainly imported from Africa and the Middle East, and included creatures such as rhinoceros, hippopotamuses, elephants, giraffes, aurochs,wisents, Barbary lions, panthers, leopards, bears, Caspian tigers, crocodiles and ostriches. Battles and hunts were often staged amid elaborate sets with movable trees and buildings. Such events were occasionally on a huge scale; Trajan is said to have celebrated his victories in Dacia in 107 with contests involving 11,000 animals and 10,000 gladiators over the course of 123 days.
Sylvae or recreations of natural scenes were also held in the arena. Painters, technicians and architects would construct a simulation of a forest with real trees and bushes planted in the arena's floor, and animals would then be introduced. Such scenes might be used simply to display a natural environment for the urban population, or could otherwise be used as the backdrop for hunts or dramas depicting episodes from mythology. They were also occasionally used for executions in which the hero of the story – played by a condemned person – was killed in one of various gruesome but mythologically authentic ways, such as being mauled by beasts or burned to death.

Today 
The Colosseum is also the site of Roman Catholic ceremonies in the 20th and 21st centuries. For instance, Pope Benedict XVI leads the Stations of the Cross called the Scriptural Way of the Cross(which calls for more meditation) at the Colosseum on Good Fridays. The Colosseum today is now a major tourist attraction in Rome with thousands of tourists each year paying to view the interior arena, though entrance for citizens of the European Union (EU) is partially subsidised, and entrance is free for EU citizens under eighteen or over sixty-five years of age. There is now a museum dedicated to Eros located in the upper floor of the outer wall of the building. Part of the arena floor has been re-floored. Beneath the Colosseum, a network of subterranean passageways once used to transport wild animals and gladiators to the arena opened to the public in summer 2010.
In 2011 Diego Della Valle, head of the shoe firm Tod's , entered into an agreement with local officials to sponsor a €25 million restoration of the Colosseum. Work is planned to begin at the end of 2011 and to take up to two and a half years.

Petra, Jordan

History

Evidence suggests that settlements had begun in and around Petra in the eighteenth dynasty of Egypt (1550-1292 BC). It is listed in Egyptian campaign accounts and the Amarna letters as Pel, Sela or Seir. Though the city was founded relatively late, a sanctuary existed there since very ancient times. Stations 19 through 26 of the stations list of Exodus are places associated with Petra. This part of the country was Biblically assigned to the Horites, the predecessors of the Edomites. The habits of the original natives may have influenced the Nabataean custom of burying the dead and offering worship in half-excavated caves. Although Petra is usually identified with Sela which means a rock, the Biblical references refer to it as "the cleft in the rock", referring to its entrance. The second book of Kings xiv. 7 seems to be more specific. In the parallel passage, however, Sela is understood to mean simply "the rock" 
On the authority of Josephus Eusebius and Jerome assert that Rekem was the native name andRekem appears in the Dead Sea Scrolls as a prominent Edom site most closely describing Petra and associated with Mount Seir. But in the Aramaic versions Rekem is the name of Kadesh, implying that Josephus may have confused the two places. Sometimes the Aramaic versions give the form Rekem-Geya which recalls the name of the village El-ji, southeast of Petra The Semitic name of the city, if not Sela, remains unknown. The passage in Diodorus Siculus (xix. 94–97) which describes the expeditions which Antigonus sent against the Nabataeans in 312 BC is understood to throw some light upon the history of Petra, but the "petra" referred to as a natural fortress and place of refuge cannot be a proper name and the description implies that the town was not yet in existence.
More satisfactory evidence of the date of the earliest Nabataean settlement may be obtained from an examination of the tombs. Two types have been distinguished: the Nabataean and the Greco-Roman. The Nabataean type starts from the simple pylon-tomb with a door set in a tower crowned by a parapet ornament, in imitation of the front of a dwelling-house. Then, after passing through various stages, the full Nabataean type is reached, retaining all the native features and at the same time exhibiting characteristics which are partly Egyptian and partly Greek. Of this type there exist close parallels in the tomb-towers at el-I~ejr in north Arabia, which bear long Nabataean inscriptions and supply a date for the corresponding monuments at Petra. Then comes a series of tombfronts which terminate in a semicircular arch, a feature derived from north Syria. Finally come the elaborate façades copied from the front of a Roman temple; however, all traces of native style have vanished. The exact dates of the stages in this development cannot be fixed. Few inscriptions of any length have been found at Petra, perhaps because they have perished with the stucco or cement which was used upon many of the buildings. The simple pylon-tombs which belong to the pre-Hellenic age serve as evidence for the earliest period. It is not known how far back in this stage the Nabataean settlement goes, but it does not go back farther than the 6th century BC.The name "Rekem" was inscribed in the rock wall of the Wadi Musa opposite the entrance to the Siq, but about twenty years ago the Jordanians built a bridge over the wadi and this inscription was buried beneath tons of concrete.
A period follows in which the dominant civilization combines Greek, Egyptian and Syrian elements, clearly pointing to the age of the Ptolemies. Towards the close of the 2nd century BC, when the Ptolemaic and Seleucid kingdoms were equally depressed, the Nabataean kingdom came to the front. Under Aretas III Philhellene, the royal coins begin. The theatre was probably excavated at that time, and Petra must have assumed the aspect of a Hellenistic city. In the reign of Aretas IV Philopatris, type may be dated, and perhaps also the great High-place.

Roman rule 
In 106 AD, when Cornelius Palma was governor of Syria, that part of Arabia under the rule of Petra was absorbed into the Roman Empire as part of Arabia Petraea, becoming capital. The native dynasty came to an end, but the city continued to flourish. It was around this time that the Petra Roman Road was built. A century later, in the time of Alexander Severus, when the city was at the height of its splendor, the issue of coinage comes to an end. There is no more building of sumptuous tombs, owing apparently to some sudden catastrophe, such as an invasion by the neo-Persian power under the Sassanid Empire. Meanwhile, as Palmyra (fl. 130–270) grew in importance and attracted the Arabian trade away from Petra, the latter declined. It seems, however, to have lingered on as a religious centre. A Roman road was constructed at the site. Epiphanius of Salamis (c.315–403) writes that in his time a feast was held there on December 25 in honor of the virgin Khaabou(Chaabou) and her offspring Dushara (Haer. 51).

Decline
Because the structures weakened with age, many of the tombs became vulnerable to thieves, and many treasures were stolen. In 1929, a four-person team, consisting of British archaeologists Agnes Conway and George Horsfield, Palestinian physician and folk-lore expert Dr Tawfiq Canaan and Dr Ditlef Nielsen, a Danish scholar, excavated and surveyed Petra. Petra declined rapidly under Roman rule, in large part from the revision of sea-based trade routes. In 363 an earthquake destroyed many buildings, and crippled the vital water management system. The ruins of Petra were an object of curiosity in the Middle Ages and were visited by Sultan Baibars of Egypt towards the end of the 13th century. The first European to describe them was Swiss traveller Johann Ludwig Burckhardt in 1812.

Religion 
The Monastery, Petra's largest monument, dates from the 1st century BC. It was dedicated to Obodas I and is believed to be the symposium of Obodas the god. This information is inscribed on the ruins of the Monastery (the name is the translation of the Arabic "Ad Deir").The Nabataeans worshipped the Arab gods and goddesses of the pre-Islamic times as well as a few of their deified kings. One, Obodas I, was deified after his death. Dushara was the main male god accompanied by his female trinity: Al-‘Uzzá, Allat and Manāt. Many statues carved in the rock depict these gods and goddesses.
Christianity found its way to Petra in the 4th century AD, nearly 500 years after the establishment of Petra as a trade center. Athanasius mentions a bishop of Petra (Anhioch. 10) named Asterius. At least one of the tombs (the "tomb with the urn"?) was used as a church. An inscription in red paint records its consecration "in the time of the most holy bishop Jason" (447). After the Islamic conquest of 629–632 Christianity in Petra, as of most of Arabia, gave way to Islam. During the First Crusade Petra was occupied by Baldwin I of the Kingdom of Jerusalem and formed the second fief of the barony of Al Karak (in the lordship of Oultrejordain) with the title Château de la Valée de Moyse or Sela. It remained in the hands of the Franks until 1189. It is still a titular see of the Catholic Church.
Two Crusader-period castles are known in and around Petra. The first is al-Wu'ayra and is situated just north of Wadi Musa. It can be viewed from the road to "Little Petra". It is the castle of Valle Moise which was seized by a band of Turks with the help of local Muslims and only recovered by the Crusaders after they began to destroy the olive trees of Wadi Musa. The potential loss of livelihood led the locals to negotiate surrender. The second is on the summit of el-Habis in the heart of Petra and can be accessed via a flight of steps that begins near the tomb complex known as "the Monastery".
According to Arab tradition, Petra is the spot where Moses (Musa) struck a rock with his staff and water came forth, and where Moses' brother, Aaron (Harun), is buried, at Mount Hor, known today as Jabal Haroun or Mount Aaron. The Wadi Musa or "Wadi of Moses" is the Arab name for the narrow valley at the head of which Petra is sited. A mountaintop shrine of Moses' sister Miriam was still shown to pilgrims at the time of Jerome in the 4th century, but its location has not been identified since.

Machu Picchu, Peru

Machu Picchu is a pre-Columbian 15th-century Inca site located 2,430 metres (7,970 ft) above sea level. Machu Picchu is located in the Cusco Region of Peru, South America. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cusco and through which the Urubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often referred to as the "Lost City of the Incas", it is perhaps the most familiar icon of the Inca World.
The Incas started building the "estate" around 1400, but abandoned it as an official site for the Inca rulers a century later at the time of the Spanish Conquest. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction. Most of the outlying buildings have been reconstructed in order to give tourists a better idea of what the structures originally looked like. By 1976, thirty percent of Machu Picchu had been restored. The restoration work continues to this day.
Since the site was never known to the Spanish during their conquest, it is highly significant as a relatively intact cultural site. Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide Internet poll.
Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary structures are the Intihuatana (Hitching post of the Sun), the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University almost reached an agreement regarding the return of artifacts which Yale has held since Hiram Bingham removed them from Machu Picchu in the early 20th century. In November 2010, a Yale University representative agreed to return the artifacts to a Peruvian university.

History

Machu Picchu was built around 1450, at the height of the Inca Empire. The construction of Machu Picchu appears to date from the period of the two great Incas, Pachacutec Inca Yupanqui (1438-71) and Tupac Inca Yupanqui (1472-93). It was abandoned just over 100 years later, in 1572, as a belated result of the Spanish Conquest. It is possible that most of its inhabitants died from smallpox introduced by travelers before the Spanish conquistadors arrived in the area. The latter had notes of a place called Piccho, although there is no record of the Spanish having visited the remote city. The types of sacred rocks defaced by the conquistadors in other locations are untouched at Machu Picchu.
Hiram Bingham theorized that the complex was the traditional birthplace of the Incan "Virgins of the Suns". More recent research by scholars such as John Howland Rowe and Richard Burger, has convinced most archaeologists that Machu Picchu was an estate of the Inca emperor Pachacuti. In addition, Johan Reinhard presented evidence that the site was selected because of its position relative to sacred landscape features such as its mountains, which are purported to be in alignment with key astronomical events important to the Incas.
Johan Reinhard believes Machu Picchu to be a sacred religious site. This theory stands mainly because of where Machu Picchu is located. Reinhard calls it "sacred geography" because the site is built on and around mountains that hold high religious importance in the Inca culture and in the previous culture that occupied the land. At the highest point of the mountain in which Machu Picchu was named after, there are “artificial platforms [and] these had a religious function, as is clear from the Inca ritual offerings found buried under them” (Reinhard 2007). These platforms also are found in other Incan religious sites. The site’s other stone structures have finely worked stones with niches and, from what the “Spaniards wrote about Inca sites, we know that these [types of] building[s] were of ritual significance” (Reinhard 2007). This would be the most convincing evidence that Reinhard points out because this type of stylistic stonework is only found at the religious sites so it would be natural that they would exist at this religious site. Another theory maintains that Machu Picchu was an Inca llaqta, a settlement built to control the economy of conquered regions. Yet another asserts that it may have been built as a prison for a select few who had committed heinous crimes against Inca society. An alternative theory is that it is an agricultural testing station. Different types of crops could be tested in the many different micro-climates afforded by the location and the terraces; these were not large enough to grow food on a large scale, but may have been used to determine what could grow where. Another theory suggests that the city was built as an abode for the deities, or for the coronation of kings.
On 24 July 1911, Hiram Bingham announced the discovery of Machu Picchu to scholars. As an American historian employed as a lecturer at Yale University, Bingham had been searching for the city of Vilcabamba, the last Inca refuge during the Spanish conquest. He had worked for years in previous trips and explorations around the zone. Pablito Alvarez, a local 11 year-old Quechua boy, led Bingham up to Machu Picchu. Some Quechuas lived in the original structures at Machu Picchu.Although the citadel is located only about 80 kilometers (50 mi) from Cusco, the Inca capital, the Spanish never found it and consequently did not plunder or destroy it, as they did many other sites. Over the centuries, the surrounding jungle grew over much of the site, and few outsiders knew of its existence.
Bingham started archaeological studies and completed a survey of the area. He called the complex "The Lost City of the Incas", which was the title of his first book. Bingham made several more trips and conducted excavations on the site through 1915, collecting various artifacts which he took back to Yale. He wrote a number of books and articles about the discovery of Machu Picchu.
The site received significant publicity after the National Geographic Society devoted their entire April 1913 issue to Machu Picchu.
In 1981 Peru declared an area of 325.92 square kilometers surrounding Machu Picchu as a "Historical Sanctuary". In addition to the ruins, the sanctuary includes a large portion of the adjoining region, rich with the flora and fauna of the Peruvian Yungas and Central Andean wet puna ecoregions.
In 1983 UNESCO designated Machu Picchu a World Heritage Site, describing it as "an absolute masterpiece of architecture and a unique testimony to the Inca civilization".
The World Monuments Fund placed Machu Picchu on its 2008 Watch List of the 100 Most Endangered Sites in the world because of environmental degradation. This has resulted from the impact of tourism, uncontrolled development in the nearby town of Aguas Calientes, which included a poorly sited tram to ease visitor access, and the construction of a bridge across the Vilcanota River, which is likely to bring even more tourists to the site, in defiance of a court order and government protests against it.

Early encounters 
The site may have been discovered and plundered in 1867 by a German businessman, Augusto Berns. There is some evidence that a German engineer, J. M. von Hassel, arrived earlier. Maps found by historians show references to Machu Picchu as early as 1874. Although Bingham was the first person to bring word of the ruins to the outside world, other outsiders were said to have seen Machu Picchu before him. Simone Waisbard, a long-time researcher of Cusco, claims that Enrique Palma, Gabino Sánchez, and Agustín Lizárraga left their names engraved on one of the rocks at Machu Picchu on 14 July 1901. In 1904, an engineer named Franklin supposedly spotted the ruins from a distant mountain. He told Thomas Payne, an English Christian missionary living in the region, about the site, Payne's family members claim. They also report that in 1906, Payne and fellow missionary Stuart E. McNairn (1867–1956) climbed up to the ruins.

Geography

The year at Machu Picchu is divided between wet and dry seasons, with the majority of annual rain falling from October through to April. It can rain at any time of the year.Machu Picchu lies in the southern hemisphere, 13.164 degrees south of the equator. It is 80 kilometers northwest of Cusco, on the crest of the mountain Machu Picchu, located about 2,450 metres (8,040 ft) above mean sea level, over 1,000 metres (3,300 ft) lower than Cusco, which has an altitude of 3,600 metres (11,800 ft). As such, it had a milder climate than the Inca capital. It is one of the most important archaeological sites in South America, one of the most visited tourist attractions in all of Latin America and the most visited tourist attraction in Peru.
Machu Picchu is situated above a loop of the Urubamba River, which surrounds the site on three sides, with cliffs dropping vertically for 450 metres (1,480 ft) to the river at their base. The area is subject to morning mists rising from the river. The location of the city was a military secret, and its deep precipices and steep mountains provided excellent natural defenses. The Inca Bridge, an Inca rope bridge, across the Urubamba River in the Pongo de Mainique, provided a secret entrance for the Inca army. Another Inca bridge was built to the west of Machu Picchu, the tree-trunk bridge, at a location where a gap occurs in the cliff that measures 6 metres (20 ft). It could be bridged by two tree trunks, but with the trees removed, there was a 570 metres (1,870 ft) fall to the base of the cliffs.
The city sits in a saddle between the two mountains Machu Picchu and Huayna Picchu, with a commanding view down two valleys and a nearly impassable mountain at its back. It has a water supply from springs that cannot be blocked easily, and enough land to grow food for about four times as many people as ever lived there. The hillsides leading to it have been terraced, not only to provide more farmland to grow crops, but to steepen the slopes which invaders would have to ascend. The terraces reduced soil erosion and protected against landslides. Two high-altitude routes from Machu Picchu go across the mountains back to Cusco, one through the sun gate, and the other across the Inca bridge. Both could be blocked easily, should invaders approach along them. Regardless of its original purpose, it is strategically located and readily defended.

Chichén Itzá, Mexico

Chichen Itza was a major focal point in the northern Maya lowlands from the Late Classic (c.600–900 AD) through the Terminal Classic (c.800–900) and into the early portion of the Early Postclassic period (c.900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.
Chichen Itza was one of the largest Maya cities and it was likely to have been one of the mythical great cities, or Tollans, referred to in later Mesoamerican literature. The city may have had the most diverse population in the Maya world, a factor that could have contributed to the variety of architectural styles at the site.
The ruins of Chichen Itza are federal property, and the site’s stewardship is maintained by Mexico’s Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History). The land under the monuments had been privately-owned until 29 March 2010, when it was purchased by the state of Yucatán.
Chichen Itza is one of the most visited archaeological sites in Mexico; an estimated 1.2 million tourists visit the ruins every year.

History

Establishment The layout of Chichen Itza site core developed during its earlier phase of occupation, between 750 and 900 AD. Its final layout was developed after 900 AD, and the 10th century saw the rise of the city as a regional capital controlling the area from central Yucatán to the north coast, with its power extending down the east and west coasts of the peninsula. The earliest hieroglyphic date discovered at Chichen Itza is equivalent to 832 AD, while the last known date was recorded in the Osario temple in 998.
The Late Classic city was centred upon the area to the southwest of the Xtoloc cenote, with the main architecture represented by the substructures now underlying the Las Monjas and Observatorio and the basal platform upon which they were built.
Ascendancy 
Chichen Itza rose to regional prominence towards the end of the Early Classic period (roughly 600 AD). It was, however, towards the end of the Late Classic and into the early part of the Terminal Classic that the site became a major regional capital, centralizing and dominating political, sociocultural, economic, and ideological life in the northern Maya lowlands. The ascension of Chichen Itza roughly correlates with the decline and fragmentation of the major centers of the southern Maya lowlands.
As Chichen Itza rose to prominence, the cities of Yaxuna (to the south) and Coba (to the east) were suffering decline. These two cities had been mutual allies, with Yaxuna dependent upon Coba. At some point in the 10th century Coba lost a significant portion of its territory, isolating Yaxuna, and Chichen Itza may have directly contributed to the collapse of both cities.
Decline 
While there is some archaeological evidence that indicates Chichén Itzá was at one time looted and sacked, there appears to be greater evidence that it could not have been by Mayapan, at least not when Chichén Itzá was an active urban center. Archaeological data now indicates that Chichen Itza declined as a regional center by 1250 CE, before the rise of Mayapan. Ongoing research at the site of Mayapan may help resolve this chronological conundrum.According to Maya chronicles (e.g., the Book of Chilam Balam of Chumayel), Hunac Ceel, ruler of Mayapan, conquered Chichen Itza in the 13th century. Hunac Ceel supposedly prophesied his own rise to power. According to custom at the time, individuals thrown into the Cenote Sagrado were believed to have the power of prophecy if they survived. During one such ceremony, the chronicles state, there were no survivors, so Hunac Ceel leaped into the Cenote Sagrado, and when removed, prophesied his own ascension.
While Chichén Itzá “collapsed” (meaning elite activities ceased) it may not have been abandoned. When the Spanish arrived, they found a thriving local population, although it is not clear from Spanish sources if Maya were living in Chichen Itza or nearby. The relatively high density of population in the region was one of the factors behind the conquistadors' decision to locate a capital there. According to post-Conquest sources, both Spanish and Maya, the Cenote Sagrado remained a place of pilgrimage.

Spanish conquest 
In 1526 Spanish Conquistador Francisco de Montejo (a veteran of the Grijalva and Cortés expeditions) successfully petitioned the King of Spain for a charter to conquer Yucatán. His first campaign in 1527, which covered much of the Yucatán peninsula, decimated his forces but ended with the establishment of a small fort at Xaman Ha', south of what is today Cancún. Montejo returned to Yucatán in 1531 with reinforcements and established his main base at Campeche on the west coast. He sent his son, Francisco Montejo The Younger, in late 1532 to conquer the interior of the Yucatán Peninsula from the north. The objective from the beginning was to go to Chichén Itzá and establish a capital.
Montejo the Younger eventually arrived at Chichen Itza, which he renamed Ciudad Real. At first he encountered no resistance, and set about dividing the lands around the city and awarding them to his soldiers. The Maya became more hostile over time, and eventually they laid siege to the Spanish, cutting off their supply line to the coast, and forcing them to barricade themselves among the ruins of ancient city. Months passed, but no reinforcements arrived. Montejo the Younger attempted an all out assault against the Maya and lost 150 of his remaining forces. He was forced to abandon Chichén Itzá in 1534 under cover of darkness. By 1535, all Spanish had been driven from the Yucatán Peninsula.
Montejo eventually returned to Yucatán and, by recruiting Maya from Campeche and Champoton, built a large Indio-Spanish army and conquered the peninsula. The Spanish crown later issued a land grant that included Chichen Itza and by 1588 it was a working cattle ranch.

Modern history
Chichen Itza entered the popular imagination in 1843 with the book Incidents of Travel in Yucatan by John Lloyd Stephens (with illustrations by Frederick Catherwood). The book recounted Stephens’ visit to Yucatán and his tour of Maya cities, including Chichén Itzá. The book prompted other explorations of the city. In 1860, Desire Charnay surveyed Chichén Itzá and took numerous photographs that he published in Cités et ruines américaines (1863).
In 1875, Augustus Le Plongeon and his wife Alice Dixon Le Plongeon visited Chichén, and excavated a statue of a figure on its back, knees drawn up, upper torso raised on its elbows with a plate on its stomach. Augustus Le Plongeon called it “Chaacmol” (later renamed “Chac Mool,” which has been the term to describe all types of this statuary found in Mesoamerica). Teobert Maler and Alfred Maudslay explored Chichén in the 1880s and both spent several weeks at the site and took extensive photographs. Maudslay published the first long-form description of Chichen Itza in his book, Biologia Centrali-Americana.
In 1894 the United States Consul to Yucatán, Edward Herbert Thompson purchased the Hacienda Chichén, which included the ruins of Chichen Itza. For 30 years, Thompson explored the ancient city. His discoveries included the earliest dated carving upon a lintel in the Temple of the Initial Series and the excavation of several graves in the Ossario (High Priest’s Temple). Thompson is most famous for dredging the Cenote Sagrado (Sacred Cenote) from 1904 to 1910, where he recovered artifacts of gold, copper and carved jade, as well as the first-ever examples of what were believed to be pre-Columbian Maya cloth and wooden weapons. Thompson shipped the bulk of the artifacts to thePeabody Museum at Harvard University.
In 1913, the Carnegie Institution accepted the proposal of archaeologist Sylvanus G. Morley and committed to conduct long-term archaeological research at Chichen Itza. The Mexican Revolution and the following government instability, as well as World War I, delayed the project by a decade.
In 1923, the Mexican government awarded the Carnegie Institution a 10-year permit (later extended another 10 years) to allow U.S. archaeologists to conduct extensive excavation and restoration of Chichen Itza. Carnegie researchers excavated and restored the Temple of Warriors and the Caracol, among other major buildings. At the same time, the Mexican government excavated and restored El Castillo and the Great Ball Court.
There have been two later expeditions to recover artifacts from the Cenote Sagrado, in 1961 and 1967. The first was sponsored by the National Geographic, and the second by private interests. Both projects were supervised by Mexico's National Institute of Anthropology and History (INAH). INAH has conducted an ongoing effort to excavate and restore other monuments in the archaeological zone, including the Ossario, Akab D’zib, and several buildings in Chichén Viejo (Old Chichen).In 1926, the Mexican government charged Edward Thompson with theft, claiming he stole the artifacts from the Cenote Sagrado and smuggled them out of the country. The government seized the Hacienda Chichén. Thompson, who was in the United States at the time, never returned to Yucatán. He wrote about his research and investigations of the Maya culture in a book People of the Serpent published in 1932. He died in New Jersey in 1935. In 1944 the Mexican Supreme Court ruled that Thompson had broken no laws and returned Chichen Itza to his heirs. The Thompsons sold the hacienda to tourism pioneer Fernando Barbachano Peon.
In 2009, to investigate construction that predated El Castillo, Yucatec archaeologists began excavations adjacent to El Castillo under the direction of Rafael (Rach) Cobos.

Taj Mahal, India

The Taj Mahal is a white marble mausoleumlocated in Agra, India. It was built by Mughal emperor Shah Jahan in memory of his third wife, Mumtaz Mahal. The Taj Mahal is widely recognized as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."
Taj Mahal is the finest example of Mughal architecture, a style that combines elements from Persian, Turkish and Indian architectural styles.
In 1983, the Taj Mahal became a UNESCO World Heritage Site. While the white domed marble mausoleum is the most familiar component of the Taj Mahal, it is actually an integrated complex of structures. The construction began around 1632 and was completed around 1653, employing thousands of artisans and craftsmen. The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision, including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri. Lahauri is generally considered to be the principal designer.

History

Soon after the Taj Mahal's completion, Shah Jahan was deposed by his son Aurangzeb and put under house arrest at nearby Agra Fort. Upon Shah Jahan's death, Aurangzeb buried him in the mausoleum next to his wife.
By the late 19th century, parts of the buildings had fallen badly into disrepair. During the time of the Indian rebellion of 1857, the Taj Mahal was defaced by British soldiers and government officials, who chiselled out precious stones and lapis lazuli from its walls. At the end of the 19th century, British viceroy Lord Curzon ordered a sweeping restoration project, which was completed in 1908. He also commissioned the large lamp in the interior chamber, modelled after one in a Cairo mosque. During this time the garden was remodelled with British-style lawns that are still in place today.

Architecture

The tomb is the central focus of the entire complex of the Taj Mahal. This large, white marble structure stands on a square plinth and consists of a symmetrical building with aniwan topped by a large dome and finial. Like most Mughal tombs, the basic elements are Persian in origin. The base structure is essentially a large, multi-chambered cube with chamfered corners, forming an unequal octagon that is approximately 55 metres (180 ft) on each of the four long sides. On each of these sides, a huge pishtaq, or vaulted archway, frames the iwan with two similarly shaped, arched balconies stacked on either side. This motif of stacked pishtaqs is replicated on the chamfered corner areas, making the design completely symmetrical on all sides of the building. Four minarets frame the tomb, one at each corner of the plinth facing the chamfered corners. The main chamber houses the false sarcophagi of Mumtaz Mahal and Shah Jahan; the actual graves are at a lower level.
The marble dome that surmounts the tomb is the most spectacular feature. Its height of around 35 metres (115 ft) is about the same as the length of the base, and is accentuated as it sits on a cylindrical "drum" which is roughly 7 metres (23 ft) high. Because of its shape, the dome is often called an onion dome or amrud (guava dome). The top is decorated with a lotus design, which also serves to accentuate its height. The shape of the dome is emphasised by four smaller domed chattris (kiosks) placed at its corners, which replicate the onion shape of the main dome. Their columned bases open through the roof of the tomb and provide light to the interior. Tall decorative spires (guldastas) extend from edges of base walls, and provide visual emphasis to the height of the dome. The lotus motif is repeated on both the chattris and guldastas. The dome and chattris are topped by a gilded finial, which mixes traditional Persian and Hindustani decorative elements.
The main finial was originally made of gold but was replaced by a copy made of gilded bronze in the early 19th century. This feature provides a clear example of integration of traditional Persian and Hindu decorative elements. The finial is topped by a moon, a typical Islamic motif whose horns point heavenward. Because of its placement on the main spire, the horns of the moon and the finial point combine to create a trident shape, reminiscent of traditional Hindu symbols of Shiva.
The minarets, which are each more than 40 metres (130 ft) tall, display the designer's penchant for symmetry. They were designed as working minarets — a traditional element of mosques, used by the muezzin to call the Islamic faithful to prayer. Each minaret is effectively divided into three equal parts by two working balconies that ring the tower. At the top of the tower is a final balcony surmounted by a chattri that mirrors the design of those on the tomb. The chattris all share the same decorative elements of a lotus design topped by a gilded finial. The minarets were constructed slightly outside of the plinth so that, in the event of collapse, (a typical occurrence with many tall constructions of the period) the material from the towers would tend to fall away from the tomb.

Interior decoration 
The interior chamber of the Taj Mahal steps far beyond traditional decorative elements. Here, the inlay work is not pietra dura, but a lapidary of precious and semiprecious gemstones. The inner chamber is an octagon with the design allowing for entry from each face, although only the door facing the garden to the south is used.
The interior walls are about 25 metres (82 ft) high and are topped by a "false" interior dome decorated with a sun motif. Eight pishtaq arches define the space at ground level and, as with the exterior, each lower pishtaq is crowned by a second pishtaq about midway up the wall. The four central upper arches form balconies or viewing areas, and each balcony's exterior window has an intricate screen or jali cut from marble. In addition to the light from the balcony screens, light enters through roof openings covered by chattris at the corners. Each chamber wall has been highly decorated with dado bas-relief, intricate lapidary inlay and refined calligraphy panels, reflecting in miniature detail the design elements seen throughout the exterior of the complex.
The octagonal marble screen or jali which borders the cenotaphs is made from eight marble panels which have been carved through with intricate pierce work. The remaining surfaces have been inlaid in extremely delicate detail with semi-precious stones forming twining vines, fruits and flowers.
Muslim tradition forbids elaborate decoration of graves. Hence, the bodies of Mumtaz and Shah Jahan were put in a relatively plain crypt beneath the inner chamber with their faces turned right and towards Mecca. Mumtaz Mahal's cenotaph is placed at the precise center of the inner chamber on a rectangular marble base of 1.5 metres (4 ft 11 in) by 2.5 metres (8 ft 2 in).
Both the base and casket are elaborately inlaid with precious and semiprecious gems. Calligraphic inscriptions on the casket identify and praise Mumtaz. On the lid of the casket is a raised rectangular lozenge meant to suggest a writing tablet. Shah Jahan's cenotaph is beside Mumtaz's to the western side, and is the only visible asymmetric element in the entire complex. His cenotaph is bigger than his wife's, but reflects the same elements: a larger casket on a slightly taller base, again decorated with astonishing precision with lapidary and calligraphy that identifies him. On the lid of this casket is a traditional sculpture of a small pen box.
The pen box and writing tablet were traditional Mughal funerary icons decorating the caskets of men and women respectively. The Ninety Nine Names of God are found as calligraphic inscriptions on the sides of the actual tomb of Mumtaz Mahal, in the crypt including "O Noble, O Magnificent, O Majestic, O Unique, O Eternal, O Glorious... ". The tomb of Shah Jahan bears a calligraphic inscription that reads; "He traveled from this world to the banquet-hall of Eternity on the night of the twenty-sixth of the month of Rajab, in the year 1076 Hijri."

The garden 
The complex is set around a large 300-metre (980 ft) square charbagh or Mughal garden. The garden uses raised pathways that divide each of the four quarters of the garden into 16 sunkenparterres or flowerbeds. A raised marble water tank at the center of the garden, halfway between the tomb and gateway with a reflecting pool on a north-south axis, reflects the image of the mausoleum. The raised marble water tank is called al Hawd al-Kawthar, in reference to the "Tank of Abundance" promised to Muhammad. Elsewhere, the garden is laid out with avenues of trees and fountains. The charbagh garden, a design inspired by Persian gardens, was introduced to India by the first Mughal emperor, Babur. It symbolises the four flowing rivers of Jannah(Paradise) and reflects the Paradise garden derived from the Persian paridaeza, meaning 'walled garden'. In mystic Islamic texts of Mughal period, Paradise is described as an ideal garden of abundance with four rivers flowing from a central spring or mountain, separating the garden into north, west, south and east.
Most Mughal charbaghs are rectangular with a tomb or pavilion in the center. The Taj Mahal garden is unusual in that the main element, the tomb, is located at the end of the garden. With the discovery of Mahtab Bagh or "Moonlight Garden" on the other side of the Yamuna, the interpretation of the Archaeological Survey of India is that the Yamuna river itself was incorporated into the garden's design and was meant to be seen as one of the rivers of Paradise. The similarity in layout of the garden and its architectural features with the Shalimar Gardens suggest that they may have been designed by the same architect, Ali Mardan. Early accounts of the garden describe its profusion of vegetation, including abundant roses, daffodils, and fruit trees. As the Mughal Empire declined, the tending of the garden also declined, and when the British took over the management of Taj Mahal during the time of the British Empire, they changed the landscaping to resemble that of lawns of London.

Outlying buildings 
The Taj Mahal complex is bounded on three sides by crenellated red sandstone walls, with the river-facing side left open. Outside the walls are several additional mausoleums, including those of Shah Jahan's other wives, and a larger tomb for Mumtaz's favourite servant. These structures, composed primarily of red sandstone, are typical of the smaller Mughal tombs of the era. The garden-facing inner sides of the wall are fronted by columned arcades, a feature typical of Hindu temples which was later incorporated into Mughal mosques. The wall is interspersed with domedchattris, and small buildings that may have been viewing areas or watch towers like the Music House, which is now used as a museum.
The main gateway (darwaza) is a monumental structure built primarily of marble which is reminiscent of Mughal architecture of earlier emperors. Its archways mirror the shape of tomb's archways, and its pishtaq arches incorporate the calligraphy that decorates the tomb. It utilises bas-relief and pietra dura inlaid decorations with floral motifs. The vaulted ceilings and walls have elaborate geometric designs, like those found in the other sandstone buildings of the complex.
At the far end of the complex, there are two grand red sandstone buildings that are open to the sides of the tomb. Their backs parallel the western and eastern walls, and the two buildings are precise mirror images of each other. The western building is a mosque and the other is the jawab (answer), whose primary purpose was architectural balance, although it may have been used as a guesthouse. The distinctions between these two buildings include the lack of mihrab(a niche in a mosque's wall facing Mecca) in the jawab and that the floors of jawab have a geometric design, while the mosque floor was laid with outlines of 569 prayer rugs in black marble. The mosque's basic design of a long hall surmounted by three domes is similar to others built by Shah Jahan, particularly to his Masjid-Jahan Numa, or Jama Masjid, Delhi. The Mughal mosques of this period divide the sanctuary hall into three areas, with a main sanctuary and slightly smaller sanctuaries on either side. At the Taj Mahal, each sanctuary opens onto an enormous vaulting dome. These outlying buildings were completed in 1643.
