Sumerian texts (3rd millennium BCE) describe the moon-god Nanna/Sin leading migrants with a bright night light and a daytime cloud.
It housed shrines dedicated to Enlil, his wife Ninlil, their sons Nanna and Ninurta, and other deities like Nuska and Suzianna.
Enlil was the father of several other important deities in the Sumerian pantheon, including Ninlil (goddess of grain and fertility) and Nanna/Sin (god of the moon).
