Baucis and Philemon

Do you remember Ovid's story of the old couple Baucis and Philemon? Zeus and Hermes had disguised themselves as peasants and had come to B and P's town, looking for accommodation. Everybody refused them hospitality but Baucis and Philemon welcomed them and Baucis realised they were gods when the pitcher of wine remained full in spite of her frequently filling their glasses. Philemon suggested killing their goose in honour of the gods but the goose leapt onto Zeus' lap and Zeus said that they shouldn't worry about the goose but instead all leave as he was so furious with the ungenerous town that he was going to destroy it. The town was completely destroyed by a flood except for Baucis and Philemon's cottage which was transformed into a temple. Zeus granted the couple a wish. They chose to stay together as guardians of the temple and to die at the same time. When they died, Baucis became a linden tree and Philemon an oak and they remained guarding the temple.
