One of the oldest Sumerian myths concerning Enlil, generally known by the title Enlil and Ninlil, tells a story modern readers and many scholars have found genuinely troubling rather than simply exotic. In it, the young goddess Ninlil is warned by her mother to avoid bathing in a particular canal because Enlil will see her and desire her; she goes anyway, and Enlil takes her by force.
For this act the assembly of the great gods judges Enlil guilty and expels him from Nippur, banishing him to the underworld despite his standing as a senior deity, a rare instance in Mesopotamian myth of even a major god facing formal consequence for a specific wrong. Ninlil, pregnant, follows him down to the world of the dead, and there Enlil, disguising himself in turn as the gatekeeper and two other underworld figures, has intercourse with her three further times, each union producing a substitute underworld deity meant to stand in for the couple's first child, the moon god Suen (Nanna), so that Nanna can be released to rise into the sky rather than remain trapped below.
The text is direct about Enlil's initial act being unwanted, and Assyriologists have written extensively about how to read a divine narrative that opens with an assault and formal punishment for it, some treating the story chiefly as an origin myth for the moon god's freedom from the underworld, others noting that the myth, unusually for the genre, does not simply excuse what Enlil does, since the gods' own judgment against him is built into the story rather than absent from it. Contested and uncomfortable as it is, the myth remains one of the fullest surviving Sumerian narratives naming Enlil directly, and it shows the tradition sometimes held even its highest gods accountable within its own moral terms.
