This was in the time of Sylla; the site is not mentioned. Dio mentions[28] a great flood in the time of Julius Cæsar, A.U.C. 694 (B.C. 59), extending as far as the great wooden theatre. The _clivus Scauri_ descends from that part of the Cœlian Hill on which the Claudium was afterwards built, to the level of the road or street that leads from the Circus Maximus to the Colosseum. All this was under water at the time of the great flood in 1871. The name of _cavea_ is said by Lipsius[29] to be applied to the amphitheatre by several classical authors. He cites Ammianus Marcellinus[30], Prudentius[31], and others, as using that name for it; but they probably meant not only the hollow where the seats were placed, but also the hollow space under the arena, with the dens for the wild beasts, to which that name was also applied. Statius[32] uses the word _cavea_ for the cages for lions, with doors round them, the closing of which frightened the lions. Livy mentions iron cages (_caveas_), but Claudian says that the animals were shut into wooden houses[33]; probably the cages in which they were brought from the _vivaria_ were of iron, but wooden cages (_pegmata_) were sufficient to place upon the lifts, and send the animals up to the trap-doors[34]. Long before this time wild beasts had been brought into Rome for exhibition, in the year 502 of Rome[35] (B.C. 251). Lucius Cæcilius Metellus, the pro-consul, when he had conquered Sicily from the Carthaginians, brought into Rome 142 elephants taken from them, which he exhibited in the Circus Maximus. The custom of sending culprits to execution by being torn to pieces by wild beasts is very ancient in the East, as the well-known history of Daniel and the lions clearly shews. The invention of circuses and amphitheatres for the exhibition of hunts is attributed to the Athenians by Cassiodorus[36]; but it is generally thought to be a Roman invention, although the name is Greek. Livy[37] records that in the year 568 of Rome (B.C. 217), Marcus Fulvius Nobilior, after the war with the Ætolians, exhibited for the first time “the athletes, and the hunting of lions and panthers.”
