Colosseum

Colosseum~One Of The New 7 Wonders Of The World

The Colosseum or Coliseum, originally the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is an eliptical amphitheatre in the centre of the city of Rome, Italy, the largest ever built in the Roman Empire. It is one of the greatest works of Roman architecture and engineering.

Occupying a site just east of the Roman Forum, its construction started between 70 and 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign.

Originally capable of seating around 50,000 spectators, the Colosseum was used for gladiatorial contests and public spectacles. It remained in use for nearly 500 years with the last recorded games being held there as late as the 6th century — well after the traditional date of the fall of Rome in 476. As well as the traditional gladiatorial games, many other public spectacles were held there, such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building eventually ceased to be used for entertainment in the early medieval era. It was later reused for such varied purposes as housing, workshops, quarters for a religious order, a fortress, a quarry and a Christian shrine.

Although it is now in a ruined condition due to damage caused by earthquakes and stone-robbers, the Colosseum has long been seen as an iconic symbol of Imperial Rome. It is one of modern Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, the Pope leading a torchlit "Way of the Cross" procession to the amphitheatre each Good Friday.

Name
The Colosseum's name has long been believed to be derived from a colossal statue of Nero nearby. This statue was later remodeled by Nero's successors into the likeness of Helios (Sol) or Apollo, the sun god, by adding the appropriate solar crown. Nero's head was also replaced several times and substituted with the heads of succeeding emperors. Despite its pagan links, the statue remained standing well into the medieval era and was credited with magical powers. It came to be seen as an iconic symbol of the permanence of Rome.

In the 8th century, the Venerable Bede (c. 672–735) wrote a famous epigram celebrating the symbolic significance of the statue: Quandiu stabit coliseus, stabit et Roma; quando cadit coliseus, cadet et Roma; quando cadet Roma, cadet et mundus ("as long as the Colossus stands, so shall Rome; when the Colossus falls, Rome shall fall; when Rome falls, so falls the world"). This is often mistranslated to refer to the Colosseum rather than the Colossus (as in, for instance, Byron's poem Childe Harold's Pilgrimage). However, at the time that Bede wrote, the masculine noun coliseus was applied to the statue rather than to what was still known as the Flavian amphitheatre.

The Colossus did eventually fall, probably being pulled down to reuse its bronze. By the year 1000 the name "Colosseum" (a neuter noun) had been coined to refer to the amphitheatre. The statue itself was largely forgotten and only its base survives, situated between the Colosseum and the nearby Temple of Venus and Roma.

The name was further corrupted to Coliseum during the Middle Ages. Both names are frequently used in modern English, but Flavian Amphitheatre is generally unknown. In Italy, the amphitheatre is still known as il colosseo, and other Romance languages have come to use similar forms such as le colisée (French), el coliseo (Spanish) and o coliseu (Portuguese).

History

Ancient
Construction of the Colosseum began under the rule of the Emperor Vespasian in around 70–72. 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 pavillions, 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 area was transformed under Vespasian and his successors. 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. The Colosseum can be thus interpreted as a great triumphal monument built in the Roman tradition of celebrating great victories. 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.

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 Coliseum was heavily damaged by a huge fire (caused by lightning, according to Dio Cassius), which destroyed the wooden upper floors of the amphitheatre, the interior fittings. It was not completely repaired, up to 240 additional repairs and underwent at 250 or 252 and 320. An inscription records the restoration of various parts of the Colosseum under Theodosius II and Valentinian III (reigned 425-450), maybe to repair the damage caused by a major earthquake in 443; more work was followed in 484 and 508th The arena continues to be used even for contests in the 6th Century, with at least 435 organized mentioned. Animal hunts continue until at least the 523rd

Medieval

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.

Severe damage was inflicted on the Colosseum by the great earthquake of 1349, causing the outer south side 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 facade) 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.

Modern
During the 16th and 17th century, Church officials sought a productive role for the vast derelict hulk of 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.

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 (see Christians and the Colosseum). Later popes initiated various stabilization and restoration projects, removing the extensive vegetation which had overgrown the structure and threatened to damage it further. The facade 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 Mussolini in the 1930s.

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 lira ($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.

Due to 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) and Elton John (September 2005).

On July 7th, 2007, the Colosseum was voted as one of New Open World Corporation's New Seven Wonders of the World.

Physical description

Exterior
Unlike earlier amphitheatres that were built into hillsides, the Colosseum is an entirely free-standing structure. It is elliptical in plan and is 189 metres (615 ft / 640 Roman feet) long, and 156 metres (510 ft / 528 Roman feet) wide, with a base area of 6 acres. The height of the outer wall is 48 metres (157 ft / 165 Roman feet). The perimeter originally measured 545 metres (1,788 ft / 1,835 Roman feet). The central arena is an oval (287 ft) long and (180 ft) wide, surrounded by a wall (15 ft) high, above which rose tiers of seating.

The outer wall is estimated to have required over 100,000 cubic meters (3,531,466 ft³) 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.

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 Doric, 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.

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 to LIV 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 (singular vomitorium), 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

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.

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 (plebians) 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.

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
The arena itself was 83 metres by 48 metres (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.

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.

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.

Supporting buildings
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.

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.

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
The Colosseum was used to host gladiatorial shows as well as a variety of other events. The shows, called munera, were always given by individuals rather than the state. They had a strong religious element but were also demonstration of power and family prestige, and were immensely popular with the population. Another popular type of show was the animal hunt, or venatio. This utilised a great variety of wild beasts, mainly imported from Africa, and included creatures such as rhinoceros, hippos, elephants, giraffes, lions, panthers, leopards, 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.

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).

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. Animals would be introduced to populate the scene for the delight of the crowd. 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 today is now a major tourist attraction in Rome with thousands of tourists each year paying to view the interior arena. 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.

Great Wall of China

Great Wall of China~One Of The New 7 Wonders Of The World

The Great Wall of China is a series of stone and mud fortifications in China, built, rebuilt, and between the 5th Century BC and the 16th Century to protect the northern border of the Chinese Empire during the reign of the subsequent dynasties. Several walls, as the Great Wall of China, have been since 5 Century BC, the most famous is the one built between 220 BC and 200 BC by the first emperor of China, Qin Shi Huang. This wall was much further north than the current wall, during the Ming Dynasty, and there remains little.

The Great Wall is the world's longest human-made structure, stretching over approximately 6,400 km (4,000 miles) from Shanhai Pass in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. It is also the largest human-made structure ever built in terms of surface area and mass.

History

The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period, which began around the 8th century BC. During the Warring States Period from the 5th century BC to 221 BC, the states of Qi, Yan and Zhao 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.
Qin Shi Huang conquered all enemy states and united China in 221 BC, to the founding of the Qin Dynasty. Do the imposition of central rule and prevent the resurgence of feudal lords, he ordered the destruction of the dividing wall sections that his former empire along the state border. To guard against intrusions into the realm of the Xiongnu people from the north, he ordered the construction of a new wall to connect the remaining fortifications along the northern reach of the new border. The transportation of large quantities of materials needed for the construction was difficult, the builders always tried to use local resources. Stones from the mountains, over mountain ranges, while rammed earth were for the construction in the plains. There are no surviving historical records indicating the exact longitude and of course the Qin Dynasty walls. Most of the ancient walls have eroded over the centuries, and only a few sections remain today. Later, Han, Sui, Northern and Jin Dynasty all repaired, rebuilt, expanded or parts of the Great Wall at great cost to defend itself against the northern invaders.
The Great Wall concept was revived again during the Ming Dynasty following the Ming army's defeat by the Mongols in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Mongols after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the Mongols 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 strengthened.

Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhai Pass, preventing the Manchus from entering the Liaodong Peninsula and the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates of Shanhai Pass were opened by Wu Sangui, a corrupt Ming border general, after being bribed. The Manchus quickly seized Beijing, and defeated the remaining Ming resistance, to establish the Qing Dynasty.

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.

Visibility

Visibility from the moon
Ripley's Believe It or Not! cartoon from May 1932 makes the claim that the wall is "the mightiest work of man, the only one that would be visible to the human eye from the moon" and Richard Halliburton's 1938 book Second Book of Marvels makes a similar claim. This belief has persisted, assuming urban legend status, sometimes even entering school textbooks. Arthur Waldron, author of history of the Great Wall, has speculated that the belief might go back to the fascination with the "canals" once believed to exist on Mars. (The logic was simple: If people on Earth can see the Martians' canals, the Martians might be able to see the Great Wall.)
The Great Wall is a maximum 30 ft (9.1m) wide and is about the same color as the soil surrounding it. Based on the optics of resolving power (distance versus the width of the iris: a few millimetres for the human eye, metres for large telescopes) an object of reasonable contrast to its surroundings some four thousand miles in diameter (such as the Australian land mass) would be visible to the unaided eye from the moon (average distance from earth 238,857 miles (384,393 km)). But the Great Wall is of course not a disc but more like a thread, and a thread a foot (15 cm) long would not be visible from a hundred yards (90 m) away, even though a human head is. Not surprisingly, no lunar astronaut has ever claimed he could see the Great Wall from the moon.

Visibility from near earth orbit

A different question is whether it is visible from near-Earth orbit, i.e at an altitude of less than 500 kilometers (311 mi) (0.1% of the distance of the moon). The consensus here is that it is barely visible, and only under nearly perfect conditions; it is no more conspicuous than many other manmade objects.

Astronaut William Pogue thought he had seen it from Skylab but discovered he was actually looking at the Grand Canal of China near Beijing. He spotted the Great Wall with binoculars, but said that "it wasn't visible to the unaided eye." US Senator Jake Garn claimed to be able to see the Great Wall with the naked eye from a space shuttle orbit in the early 1980s, but his claim has been disputed by several US astronauts. Chinese astronaut Yang Liwei said he could not see it at all.

Veteran US astronaut Gene Cernan has stated: "At Earth orbit of 160 kilometers (99 mi) to 320 kilometers (199 mi) high, the Great Wall of China is, indeed, visible to the naked eye." Ed Lu, Expedition 7 Science Officer aboard the International Space Station, adds that, "it's less visible than a lot of other objects. And you have to know where to look."

Neil Armstrong explained about the prospect of Apollo 11: "I do not believe that at least in my eyes, there would be no man-made objects, which I could see. I have not yet found somebody who told me that she had seen , The Wall of China from Earth orbit. ... I have asked various people, especially boys shuttle, which have many cars around China in the day, and those who I have spoken to do not see him . "

Leroy Chiao, a Chinese-American astronaut, took a photograph from the International Space Station that shows the wall. It was so indistinct that the photographer was not certain he had actually captured it. Based on the photograph, the state-run China Daily newspaper concluded that the Great Wall can be seen from space with the naked eye, under favorable viewing conditions, if one knows exactly where to look.

Petra

Petra~One Of The New 7 Wonders Of The World

Petra (from πέτρα "petra," rock in Greek; Arabic: البتراء, Al-Butrā) is an archaeological site in Jordan, lying in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It is well known that many structures of stone carved in the rocks. The long-hidden site was revealed to the Western world by the Swiss explorer Johann Ludwig Burckhardt in 1812. It was famously described as "a rose-red city half as old as time" in a Newdigate prize-winning sonnet by John William Burgon. Burgon had not actually visited Petra, which remained accessible only to Europeans accompanied by local guides with armed escorts until after World War I. The site was designated as a UNESCO World Heritage Site in 1985 when it was described as "one of the most precious cultural properties of man's cultural heritage."

Geography

Rekem is an ancient name for Petra and appears in Dead Sea scrolls such as 4Q462 associated with Mount Seir. Additionally, Eusebius and Jerome (Onom. sacr. 286, 71. 145, 9; 228, 55. 287, 94) assert that Rekem was the native name of Petra, supposedly on the authority of Josephus (Antiquities iv. 7, 1~ 4, 7), Pliny the Elder and other writers identify Petra as the capital of the Nabataeans, Aramaic-speaking Semites, and the centre of their caravan trade. Enclosed by towering rocks and watered by a perennial stream, Petra not only possessed the advantages of a fortress but controlled the main commercial routes which passed through it to Gaza in the west, to Bosra and Damascus in the north, to Aqaba and Leuce Come on the Red Sea, and across the desert to the Persian Gulf.

Excavations have shown that the ability of the Nabataeans, the water supply has led the increase in the desert city, in fact, the creation of an artificial oasis. The area is visited by flash floods and archaeological evidence demonstrates the Nabataeans controlled these floods by the use of dams, cisterns and water conduits. So water could be saved even during long periods of drought, and the city prospered from its sale.

Although in ancient times Petra might have been approached from the south (via Saudi Arabia on a track leading around Jabal Haroun, Aaron's Mountain, on across the plain of Petra), or possibly from the high plateau to the north, most modern visitors approach the ancient site from the east. The impressive eastern entrance leads steeply down through a dark and narrow gorge (in places only 3–4 metres wide) called the Siq (the shaft), a natural geological feature formed from a deep split in the sandstone rocks and serving as a waterway flowing into Wadi Musa. At the end of the narrow gorge stands Petra's most elaborate ruin, Al Khazneh ("the Treasury") hewn directly out of the sandstone cliff.

A little farther from the Treasury, at the foot of the mountain called en-Nejr is a massive theatre, so placed as to bring the greatest number of tombs within view. At the point where the valley opens out into the plain, the site of the city is revealed with striking effect. The amphitheatre has actually been cut into the hillside and into several of the tombs during its construction. Rectangular gaps in the seating are still visible. Almost enclosing it on three sides are rose-colored mountain walls, divided into groups by deep fissures, and lined with knobs cut from the rock in the form of towers.

History

So far, no method has been found to determine when the story of Petra began. There are indications that the city was established relatively late, although there may be a sanctuary since very ancient times. This part of the country was traditionally assigned to the Horites, probably cave-dwellers, 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. However, the fact that Petra is mentioned by name in the Old Testament cannot be verified. Although Petra is usually identified with Sela which also means a rock, the Biblical references are not clear. 2 Kings xiv. 7 seems to be more specific. In the parallel passage, however, Sela is understood to mean simply "the rock" (2 Chr. xxv. 12, see LXX). As a result, many authorities doubt whether any town named Sela is mentioned in the Old Testament.

It is unclear exactly what Semitic inhabitants called their city. Apparently on the authority of Josephus (Antiquities of the Jews iv. 7, 1~ 4, 7), Eusebius and Jerome (Onom. sacr. 286, 71. 145, 9; 228, 55. 287, 94), assert that Rekem was the native name and Rekem appears in the Dead Sea scrolls as a prominent Edom site most closely describing Petra. 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 capital, however, would hardly be defined by the name of a neighboring village. 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. Brünnow thinks that "the rock" in question was the sacred mountain en-Nejr (above). But Buhl suggests a conspicuous height about 16 miles north of Petra, Shobak, the Mont-royal of the Crusaders.

More satisfactory evidence of the date of the earliest Nabataean settlement may be obtained from an examination of the tombs. Two types may be 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 quit, in a semicircular arc, a feature from northern Syria. Finally, the elaborate facades copied from the front of a Roman temple. But all traces of the indigenous style disappeared. The exact dates of the phases of this development can not be repaired. Strangely, some inscriptions have been found at any length Petra, perhaps lost because they are compatible with stucco or cement was used on many of the buildings. The simple pylon tombs, which belong to the pre-Hellenic Age serve as evidence for the earliest time. It is not known how far back at this stage of Nabataean settlement, but it goes no further back than the 6th Century BC.

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, (c.85–60 BC), 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, (9 BC–AD 40), the fine tombs of the el-I~ejr [?] type may be dated, and perhaps also the great High-place.
