9 BC, Rome:
"This same year Vedius Pollio died, a man who in general had done nothing deserving of remembrance, as he was sprung from freedmen, belonged to the knights, and had performed no brilliant deeds; but he had become very famous for his wealth and for his cruelty, so that he has even gained a place in history. He kept in reservoirs huge lampreys that had been trained to eat men, and he was accustomed to throw to them such of his slaves as he desired to put to death. Once, when he was entertaining the Emperor Augustus, his cup-bearer broke a crystal goblet, and without regard for his guest, Pollio ordered the fellow to be thrown to the lampreys. Hereupon the slave fell on his knees before Augustus and supplicated him, and Augustus at first tried to persuade Pollio not to commit so monstrous a deed. Then, when Pollio paid no heed to him, the emperor said, 'Bring all the rest of the drinking vessels which are of like sort or any others of value that you possess, in order that I may use them,' and when they were brought, he ordered them to be broken. When Pollio saw this, he was vexed, of course; but since he was no longer angry over the one goblet, considering the great number of the others that were ruined, and, on the other hand, could not punish his servant for what Augustus also had done, he held his peace, though much against his will."

2008 AD, southern Italy:
"Police rescued two teenage Bulgarian sisters from a circus in southern Italy which forced one of them to swim with flesh-eating piranhas for the amusement of guests, police said.
While the 19-year-old sister swam in a transparent tank, the younger, 16-year-old was forced into a container where the circus staff tossed snakes at her. She was injured by one of the snakes, police said. Police arrested three Italians who ran the circus south of Naples, in Salerno province, accusing them of forcing the sisters to live in virtual slavery. The women were paid 100 euros ($155.8) per week and lived in a trailer that had previously been used to transport animals, they said.
