Sin / Nanna

Nanna, Sīn /ˈsiːn/ or Suen (Akkadian: EN.ZU, pronounced Su'en, Sen, Sîn), and in Aramaic syn, syn’, or even shr 'moon', or Nannar (Sumerian: DŠEŠ.KI, DNANNAR) was the god of the moon in the Mesopotamian religions of Sumer, Akkad, Assyria, Babylonia and Aram. He was also associated with cattle, perhaps due to the perceived similarity between bull horns and the crescent moon. He was always described as a major deity, though only a few sources, mostly these from the reign of Nabonidus, consider him to be the head of the Mesopotamian pantheon.
