Lamashtu was a malign and malevolent demon, monster, or goddess in Mesopotamian lore. She menaced women during childbirth and kidnapped children while breastfeeding, much like the Lilim of similar legends. Lamashtu's father was the Sky God Anu. Unlike many other usual demonic figures and depictions in Mesopotamian lore, Lamashtu was said to act in malevolence of her own accord, rather than at the gods' instructions.
She would gnaw on their bones and suck their blood, like a vampire, as well as being charged with a number of other evil deeds. Lamashtu is depicted as a mythological hybrid, with a hairy body, a lioness' head with donkey's teeth and ears, long fingers and fingernails, and the feet of a bird with sharp talons. She is often shown standing or kneeling on a donkey, nursing a pig and a dog, and holding snakes.
She bore seven names and was described as seven witches in incantations. Her evil deeds included (but were not limited to): slaying children, unborns, and neonates; causing harm to mothers and expectant mothers; eating men and drinking their blood; disturbing sleep; bringing nightmares; killing foliage; infesting rivers and lakes; and being a bringer of disease, sickness, and death.
