Beneath the Official Pantheon Was a Layer of Demons

Beneath the official pantheon, including the likes of Enlil, the Assyrian sky god, and Ea, the god of wisdom, was a layer of demons, such as Lamashtu, who threatened pregnant women, and Namtaru, the plague-demon, who needed to be mollified. Natural phenomena such as floods and lightning, or epidemic diseases, were not scientifically understood despite Mesopotamian advances, and so people at all levels of society preferred supernatural explanations. Disasters were believed to be caused by mamitu (curses) laid by witches, by victims committing offenses (sometimes unknowingly) against the gods, or through unintentionally ignoring divine signs. Kings guarded against these occurrences by consulting temple priests, in particular ashipu (exorcists), who performed magical rituals, and baru, who interpreted omens. Palace archives were stocked with collections of clay cuneiform tablets containing spells, incantations, and omens. Huge numbers have been recovered from the palace library of the Assyrian king Ashurbanipal. Ordinary people also called on the services of ashipu to cast protective spells, and used amulets and enchanted figurines to dispel evil spirits.
