In Greek mythology , a pious old couple in Phrygia.
When Zeus and Hermes , disguised as wayfarers, had been turned away by the couple's richer neighbors, Philemon and Baucis extended them hospitality. As a reward they were spared when a flood swept the countryside. Their cottage was turned into a temple, and they became priest and priestess of it. Years later they were granted their wish to die at the same moment, and they were turned into trees.
