Bk VIII:679-724 The transformation of Philemon and Baucis.
"Meanwhile the old couple noticed that, as soon as the mixing bowl was empty, it refilled itself, unaided, and the wine appeared of its own accord. They were fearful at this strange and astonishing sight, and timidly Baucis and Philemon murmured a prayer, their palms upwards, and begged the gods' forgiveness for the meal, and their un-preparedness. They had a goose, the guard for their tiny cottage: as hosts they prepared to sacrifice it for their divine guests. But, quick-winged, it wore the old people out and, for a long time, escaped them, at last appearing to take refuge with the gods themselves. Then the heaven-born ones told them not to kill it. 'We are gods,' they said, 'and this neighbourhood will receive just punishment for its impiety, but to you we grant exemption from that evil. Just leave your house, and accompany our steps, as we climb that steep mountainside together.'
They both obeyed, and leaning on their sticks to ease their climb, they set foot on the long slope. When they were as far from the summit as a bowshot might carry, they looked back, and saw everywhere else vanished in the swamp: only their own roof was visible. And while they stood amazed at this, mourning their neighbours' fate, their old cottage, tiny even for the two of them, turned into a temple. Wooden poles became pillars, and the reed thatch grew yellow, until a golden roof appeared, richly carved doors, and a marble pavement covering the ground. Then the son of Saturn spoke, calmly, to them: 'Ask of us, virtuous old man, and you, wife, worthy of a virtuous husband, what you wish.'
When he had spoken briefly with Baucis, Philemon revealed their joint request to the gods. 'We ask to be priests and watch over your temple, and, since we have lived out harmonious years together, let the same hour take the two of us, so that I never have to see my wife's grave, nor she have to bury me.' The gods' assurance followed the prayer. They had charge of the temple while they lived: and when they were released by old age, and by the years, as they chanced to be standing by the sacred steps, discussing the subject of their deaths, Baucis saw Philemon put out leaves, and old Philemon saw Baucis put out leaves, and as the tops of the trees grew over their two faces, they exchanged words, while they still could, saying, in the same breath: 'Farewell, O dear companion,' as, in the same breath, the bark covered them, concealing their mouths.
The people of Bithynia still show the neighbouring trees, there, that sprang from their two bodies. Trustworthy old men related these things to me (there was no reason why they should wish to lie). For my part, I saw garlands hanging from the branches, and placing fresh ones there said: 'Let those who love the gods become gods: let those who have honoured them, be honoured.' "
