Ningishzida was "Lord of the Steadfast Tree," a god of the underworld and of vegetation that springs from it; his emblem was a serpent, or rather two serpents intertwined upon a staff, an image preserved on Sumerian seals from at least the third millennium BCE. He was the throne-bearer of Ereshkigal, and a guardian of the gates of the great below. The kings of the city of Lagash, in particular Gudea, claimed him as their personal god, and Gudea's many statues regularly invoke his name.

Curator’s note
What the sources say, and what later tradition added. The sources for this bay
The image of two snakes entwined upon a staff associated with Ningishzida is, to all appearances, the most ancient ancestor of the caduceus that came centuries later to be associated with Hermes. Whether the iconography was transmitted continuously, or whether the resemblance is convergent, is debated; but the form is certainly attested in Mesopotamia far earlier than in Greece. Ningishzida's myth is preserved chiefly in the lament Ningishzida's Journey to the Netherworld (Sumerian, Old Babylonian copies), in which the young god is taken below, mourned by his sister, and received among the dead.
