One of a series of pictures from the Iron Age.

It's interesting to realize Nabonidus venerated this god. From WEikipedia: Sīn /ˈsiːn/ or Suen (Akkadian: 𒂗𒍪 EN.ZU, pronounced Su'en, Sîn)[1] or Nanna (Sumerian: 𒀭𒋀𒆠 DŠEŠ.KI, DNANNA) was the god of the moon in the Mesopotamian religions of Sumer, Akkad, Assyria and Babylonia. Nanna is a Sumerian deity, the son of Enlil and Ninlil, and became identified with the Semitic Sīn. The two chief seats of Nanna's/Sīn's worship were Ur in the south of Mesopotamia and Harran in the north.

This stele is in basalt, and indeed is from Harran.
