The Nasnas (Arabic: نسناس nasnās) is a weak form of jinn, hybrids of human-like and animal-like forms, and may account for some of our encounters with mysterious creatures. According to Edward Lane, the 19th century translator of The Book of 1001 Nights, a nesnas is "half a human being; having half a head, half a body, one arm, one leg, with which it hops with much agility".
The nasnas was said to be the offspring of a jinni called a Shiqq 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 which says:
- "The Nisnas (have only one eye, one cheek, one hand, one leg, half a body, half a heart. They say): "We live quiet in our halves of houses, with our halves of wives and our halves of children!""
