Ninazu, whose name signifies "Lord Physician," was a son of the underworld queen Ereshkigal (and, by some accounts, of Enlil and Ninlil). His city was Eshnunna, and a second seat at Enegi; he was a chthonic god, with serpent associations, and a healer like his attendant Ningishzida. The medical and the underworld offices commingled in him: he could send the sickness, and he could withhold it.

Curator’s note
What the sources say, and what later tradition added. The sources for this bay
Ninazu is attested from at least the Early Dynastic period (mid-third millennium BCE). His cult at Eshnunna was important in the Old Babylonian period. By the second millennium, much of his medical office was transferred to Gula. The conjunction of underworld and healing in a single deity is paralleled in the later Greek Asclepius, whose chthonic associations and serpent emblem also derive from a long Aegean tradition of subterranean healing-cults; the Mesopotamian and Greek traditions are very probably independent expressions of a widespread ancient pattern.
