In fact Mavros is modelled exactly on the island of Lesbos, where Graham lived for a year early in his writing career. The house referred to was where he lived during that time, and the eponymous name of the house was not an invention. It is to be found near the village of Petra, "close enough to Turkey to hear the donkeys braying on the mainland". The mysterious bath referred to in the novel is the ancient hot spring at Eftalou; the church with the evil-eye mural is in the village of Molyvos; and the myth of the angel-militant in metal shoes is still widely believed on the island.
