Exquisite detail and colouring to this image of the elderly couple, Baucis and Philemon seated outside their house, with vines twined among the columns and the village in the background - exquisite colouring.

In Ovid's Metamorphoses, which stands on the periphery of Greek mythology and Roman mythology, Baucis and Philemon were an old married couple in the region of Tyana, who were the only ones in their town to welcome disguised gods Zeus and Hermes (in Roman mythology, Jupiter and Mercury)
Zeus and Hermes disguised themselves as ordinary peasants and asked the people of the town for a place to sleep. They were rejected by all before they came to Baucis and Philemon's rustic and simple cottage. Though the couple were poor, they showed more pity than their rich neighbors, where "all the doors bolted and no word of kindness given, so wicked were the people of that land." After serving the two guests food and wine, which Ovid depicts with pleasure in the details, Baucis noticed that although she had refilled her guest's beechwood cups many times, the wine pitcher was still full. Realizing that her guests were in fact gods, she and her husband "raised their hands in supplication and implored indulgence for their simple home and fare." (Wikipedia)
