in popular legend, demonic being believed to inhabit burial grounds and other deserted places. In ancient Arabic folklore, ghūls belonged to a diabolic class of jinn (spirits) and were said to be the offspring of Iblīs, the Muslim prince of darkness. They were capable of constantly changing form, but their presence was always recognizable by their unalterable sign: ass's hooves.

Considered female by the ancients, the ghūl was often confused with the sílā, also female; the sílā, however, was a witchlike species of jinn, immutable in shape. A ghūl stalked the desert, often in the guise of an attractive woman, trying to distract travelers, and, when successful, killed and ate them. The sole defense that one had against a ghūl was to strike it dead in one blow; a second blow would only bring it back to life again.

The ghūl, as a vivid figure in the Bedouin imagination, appeared in pre-Islāmic Arabic poetry, notably that of Taʿabbata Sharran. In North Africa, it was easily assimilated into an ancient Berber folklore already rich in demons and fantastic creatures. Modern Arabs use ghūl to designate a human or demonic cannibal and frequently employ the word to frighten disobedient children.

Anglicized as “ghoul,” the word entered English tradition and was further identified as a grave-robbing creature that feeds on dead bodies and on children. In the West ghouls have no specific image and have been described (by Edgar Allan Poe) as “neither man nor woman . . . neither brute nor human.” They are thought to assume disguises, to ride on dogs and hares, and to set fires at night to lure travelers away from the main roads.
