Allatu is the chief goddess of the subterranean cave in which the dead dwell, and seems sometimes, like Nergal, to have been depicted as a lion. As mistress of the underworld, she is regarded sometimes as the authoress of evil, though as a personification of the "earth" she seems also to have been considered a goddess of fertility. The El-Amarna tablets seek to explain Nergal's position in the world of the dead by the legend of a conflict between Nergal and Allatu. In the end she offers to marry him, and he spares her life. The legend seems to have been framed in imitation of the Marduk-Tiamat story. (An Encyclopedia of Religions, Canney, 1921)
The Goddesses Al-Uzza, Al-Lat and Menat formed a triad in pre-Islamic Arabia.
