"Caracalla, the fierce and aggressive Roman emperor, was indeed proud of his zebras. Named for the long cloak or caracallus he made popular, he lavished money on completing the vast public baths and on the circuses, of which there were several in Rome. On special occasions the zebras were harnessed to an elaborately decorated cart and led the procession of wild animals as they entered the arena before gladiatorial combats and chariot races."
