The male Lilû and the two females Lilītu and the Artdat-lilî are a sort of family group of demons. They are not gods. The Lilû haunts the desert and open country and is especially dangerous to pregnant women and infants. The Lilītu seems to be a female equivalent, while the Artdat-lilî (whose name means 'maiden Lilû') seems to have the character of a frustrated bride, incapable of normal sexual activity. As such, she compensates by aggressive behavior especially towards young men. The Artdat-lilî, who is often mentioned in magical texts, seems to have some affinities with the Jewish Lilith (e.g. Isaiah 34:14). 'She is not a wife, a mother; she has not known happiness, has not undressed in front of her husband, has no milk in her breasts.' She was believed to cause impotence in men and sterility in women.
