Patmos is a small Greek island that is mentioned in the title of the the Sandro di Garagiola fresco, Pope Sporus Being Begged by the Curia Not to Abdicate and Go To Live on Patmos as a Hermit (Saint Fidgeta and Other Parodies, 57).
Patmos is a small Greek island in the Aegean Sea, most famous for being the location of both the vision of and the writing of the Christian Bible's Book of Revelation. The book's introduction states that its author, John, was on Patmos when he was given (and recorded) a vision from Jesus. Because of the Book of Revelation, Patmos has a long history as a destination for Christian pilgrimage. Visitors can see the cave where John is said to have received his Revelation, and several monasteries on the island are dedicated to Saint John.
