[Picture: Pandora] The gods undertook also to accept sacrifices, claiming a share in whatever animal man slew.  Prometheus guarded his people here by putting the flesh of a bullock on one side, and the bones and inward parts covered with the fat on the other, and bidding Jupiter choose which should be his.  The fat looked as if the heap it covered were the best, and Jupiter chose that, and was forced to abide by his choice; so that, whenever a beast was killed for food, the bones and fat were burnt on the altar, and man had the flesh.  All this made Jupiter so angry, that, as Prometheus was immortal and could not be killed, he chained the great, good Titan to a rock on Mount Caucasus, and sent an eagle continually to rend his side and tear out his liver as fast as it grew again; but Prometheus, in all his agony, kept hope, for he knew that deliverance would come to him; and, in the meantime, he was still the comforter and counsellor of all who found their way to him.
