A nasnas is a monstrous creature in Arab mythology. According to Edward Lane, the 19th century translator of The Arabian Nights, a nasnas is "half a human being; having half a head, half a body, one arm, one leg, with which it hops with much agility". It was believed to be the offspring of a demon called a Shikk and a human being. A character in "The Story of the Sage and the Scholar", a tale from the collection, is turned into a nasnas after a magician applies kohl to one of his eyes. The nasnas is mentioned in Gustave Flaubert's The Temptation of Saint Anthony.
