The story of Baucis and Philemon: Example of Kharis and Xenia in ancient Hellas
"Zeus and His son Hermes descended to earth to test the hospitality of the little town that is home to the elderly couple of Baucis and Philemon, who live in a run down hut a little ways away from the small, rural village. The Gods are dressed as simple travellers, weary from their long journey on foot. They knock on the doors of all of the houses in the village but find no one willing to open the door and take them in. With every house the Gods pass, the anger of the Gods rises, but before They punish this town for their despicable ways, They decide to test the last house in the village as well; the house of Baucis and Philemon.
It is Philemon who opens the door after the first knock and begs the travellers to enter. The hut is tiny and the two, who have been together for almost all of their long years, have not much to give. Still, the two bustle around the hut to repair enough stools for all to sit, to find enough food for all to eat and, as the night progresses, enough places for all to sleep. Neither Baucis nor Philemon realizes the true nature of their guests until they realize the small jug of wine has not run out, betraying the divinity of their guests.
Both Baucis and Philemon throw themselves down in front of the Gods, begging for forgiveness for such a sorry welcome but the Gods, who have not been offended in the least, beg them to rise and walk out with Them, to the top of the hill. There, Zeus turns to the village and floods the valley completely, killing all residents. He spares the hut that belongs to Baucis and Philemon and even transforms it into a temple. He then asks what favour the pair would want from the Gods, as they have truly deserved one. The pair asks to honour the Gods for their remaining years in the temple created below and ask that, when their dying day comes, that they may go together so they will never be without the other. This, the Gods grant happily."
