colloseo

The Colosseum's original Latin name was Amphitheatrum Flavium, often anglicized as Flavian Amphitheater. The building was constructed by emperors of the Flavian dynasty, hence its original name. This name is still used frequently in modern English, but it is generally unknown. In antiquity, Romans may have referred to the Colosseum by the unofficial name Amphitheatrum Caesareum; this name could have been strictly poetic. This name was not exclusive to the Colosseum; Vespasian and Titus, builders of the Colosseum, also constructed an amphitheater of the same name in Puteoli (modern Pozzuoli).

The name Colosseum 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. 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).
