Aristæus was the son of Apollo, and the water-nymph, Cyrene. Beside tending his flocks and herds, he took care of the olive trees and vineyards, and was a famous keeper of bees. He was very proud of his hives, and the swarm of bees increased each year under the guidance of his skillful hands; but one day he found hundreds of the bees lying lifeless beside the hives, and on the morrow there were still more among the dead. Not knowing how to account for this disaster, Aristæus hurried to his mother to ask her help in saving the few bees that remained. Cyrene lived under a mountain stream; and, hearing that her son wished to speak to her, she commanded the river to divide and form a wall on either side, so that Aristæus might walk in dry places. When the youth told her of the tragedy befalling his hives, she could not help him, but bade him go to old Proteus, for he alone could tell what the trouble was and find a remedy. She warned Aristæus of the difficulty in holding the Ancient of the Deep when he tried to bewilder and terrify the stranger by rapidly assuming different forms; and she bade him remember that he must keep the sea-god fast bound if he would receive the wished-for answers. Then she led him to the cave of Proteus and hid him there, exhorting him to be bold and fearless. At noon the Wizard of the Deep came up out of the sea, followed by his herd of sea-calves; and while they lay stretched out on the warm sands, the god sought the retreat of his cave and soon was in a deep slumber. When Aristæus saw Proteus fast asleep, he stepped cautiously up to him and bound him with strong fetters. The god woke with a start, and tried to shake himself free of his chains; but on finding that he was a prisoner, he resorted to all the trickery that he could command. He became a fire, a flood, a wild beast, a horrible serpent, and many other forms calculated to terrify the beholder. But Aristæus was not afraid, and soon the old wizard realized that he must submit; so he assumed his own shape, and asked the youth what it was that he wished to know. The son of Cyrene told him of the death of his bees, and begged for some remedy. Then Proteus reminded him of how he had been the real cause of Eurydice's death, by making her flee from him in such haste that she did not see the snake at her feet.[52] The wood-nymphs, who were Eurydice's companions, had therefore wished to punish Aristæus, and had sent this destruction to his hives. It was necessary to appease the wrath of the nymphs; and to do this Proteus bade the youth build four altars, and sacrifice on them four bulls and four cows of perfect form and size. This burnt-offering was to placate the nymphs, and when it was made, he must pay funeral honors to Orpheus and Eurydice to pacify their anger against him. At the end of nine days he was to return to the grove where he had made the sacrifices.
