Hursag (transcribed cuneiform: ḫur.saḡ(HUR.SAG)) is a Sumerian term variously translated as meaning "mountain", "hill", "foothills" or "piedmont". Thorkild Jacobsen extrapolated the translation in his later career to mean literally, "head of the valleys". Mountains play a certain role in Mesopotamian mythology and Assyro-Babylonian religion, associated with deities such as Anu, Enlil, Enki and Ninhursag.
