In Sumerian and Akkadian (Babylonian and Assyrian) mythology, Gallu[1] (also called gallu demon or galla [Akkadian: gallû[2]]) is a great underworld demon or devil.
Gallu demons hauled unfortunate victims off to the underworld. The gallas are one of seven devils (or "the offspring of hell") of Babylonian theology who can be appeased by the sacrifice of a lamb at their altars.[3] Inana (or Ishtar) is accompanied by galla(s) as she is on a journey to the underworld.[3]
The word gallu may also refer to a human enemy.[4]
