Numerous acts of the most odious barbarity were committed. The well-known anecdotes of Flaminius ordering a slave to be killed to gratify, by the spectacle, the curiosity of a guest; of Vedius Pollio feeding his fish on the flesh of slaves; and of Augustus sentencing a slave, who had killed and eaten a favourite quail, to crucifixion, are the extreme examples that are recorded; for we need not regard as an historical fact the famous picture in Juvenal of a Roman lady, in a moment of caprice, ordering her unoffending servant to be crucified. We have, however, many other very horrible glimpses of slave life at the close of the Republic and in the early days of the Empire. The marriage of slaves was entirely unrecognised by law, and in their case the words adultery, incest, or polygamy had no legal meaning. Their testimony was in general only received in the law-courts when they were under torture. When executed for a crime, their deaths were of a most hideous kind. The ergastula, or private prisons, of the masters were frequently their only sleeping-places. Old and infirm slaves were constantly exposed to perish on an island of the Tiber. We read of slaves chained as porters to the doors, and cultivating the fields in chains. Ovid and Juvenal describe the fierce Roman ladies tearing their servants’ faces, and thrusting the long pins of their brooches into their flesh. The master, at the close of the Republic, had full power to sell his slave as a gladiator, or as a combatant with wild beasts.(570)
