Proteus (Roman)

According to Virgil in the fourth Georgic, at one time the bees of Aristaeus, son of Apollo, all died of a disease. Aristaeus went to his mother, Cyrene, for help; she told him that Proteus could tell him how to prevent another such disaster, but would do so only if compelled. Aristaeus had to seize Proteus and hold him, no matter what he would change into. Aristaeus did so, and Proteus eventually gave up and told him that the bees' death was a punishment for causing the death of Eurydice. To make amends, Aristaeus needed to sacrifice 12 animals to the gods, leave the carcasses in the place of sacrifice, and return three days later. He followed these instructions, and upon returning, he found in one of the carcasses a swarm of bees which he took to his apiary. The bees were never again troubled by disease.
