The name Colosseum does not refer to the building itself, but to a colossal bronze statue of Emperor Nero that once stood nearby. This giant sculpture, known as the Colossus Solis, was moved to the amphitheater's entrance by Emperor Hadrian in the 2nd century AD, and the structure eventually inherited the name derived from the statue. By the year 1000, the Latin term Colosseum had been coined to describe the amphitheater, originating from the adjective colosseus, meaning gigantic. A medieval prophecy attributed to the Venerable Bede in the 8th century linked the fate of the statue to the fate of Rome, stating that as long as the Colossus stood, so would Rome, and when the Colossus fell, Rome would fall. This prophecy was often mistranslated to refer to the amphitheater rather than the statue, creating a lasting association between the ruin and the end of the world. The building itself was originally known simply as the Amphitheatrum, and the name Colosseum was not used in classical antiquity, emerging only centuries later as the statue was lost to history.
Blood and Empire
Construction of the amphitheater began in 72 AD under Emperor Vespasian, funded by the opulent spoils taken from the Jewish Temple after the First Jewish-Roman War in 70 AD. An inscription found on the site reveals that the emperor ordered the new amphitheater to be erected from his general's share of the booty, utilizing a massive workforce that included slaves and prisoners of war alongside professional Roman builders. The project was completed in 80 AD under Vespasian's successor, Titus, and inaugurated with games that lasted for 100 days, during which over 9,000 wild animals were killed. The site chosen for the construction was a flat area in a low valley between the Caelian, Esquiline, and Palatine Hills, which had previously been the location of Nero's Domus Aurea, or Golden House. Vespasian's decision to build the Colosseum on the site of Nero's artificial lake was a populist gesture intended to return the land to the people, placing the structure in the heart of Rome rather than on the outskirts. The Flavian dynasty, consisting of Vespasian, Titus, and Domitian, were the patrons of the work, and the amphitheater was later named the Flavian Amphitheater by classicists to honor their family name.Engineering the Crowd
The Colosseum is an elliptical structure measuring 189 meters in length and 156 meters in width, with an outer wall standing 48 meters high. It was built using travertine limestone, tuff, and brick-faced Roman concrete, held together by 300 tons of iron clamps that were later pried out by stone robbers, leaving the pockmarks visible today. The architects designed the building to handle massive crowds, incorporating 80 entrances at ground level, 76 of which were used by ordinary spectators. Each entrance and exit was numbered, and spectators were given tickets in the form of numbered pottery shards that directed them to specific sections. The venue utilized vomitoria, passageways that opened into tiers of seats from below, allowing the rapid discharge of people into their seats or their quick evacuation in an emergency. A retractable awning known as the velarium covered two-thirds of the arena, operated by sailors specially enlisted from the Roman naval headquarters at Misenum. The seating arrangement reflected the rigidly stratified nature of Roman society, with special boxes for the Emperor and Vestal Virgins, a podium for the senatorial class, and distinct tiers for knights, ordinary citizens, and the poor.
