Sin

Sin () or Suen (Akkadian: 𒀭𒂗𒍪, dEN.ZU) also known as Nanna (Sumerian: 𒀭𒋀𒆠 DŠEŠ.KI, DNANNA) is the Mesopotamian god representing the moon. While these two names originate in two different languages, respectively Akkadian and Sumerian, they were already used interchangeably to refer to one deity in the Early Dynastic period. They were sometimes combined into the double name Nanna-Suen. A third well attested name is Dilimbabbar (𒀭𒀸𒁽𒌓). Additionally, the name of the moon god could be represented by logograms reflecting his lunar character, such as d30 (𒀭𒌍), referring to days in the lunar month or dU4.SAKAR (𒀭𒌓𒊬), derived from a term referring to the crescent. In addition to his astral role, Sin was also closely associated with cattle herding. Furthermore, there is some evidence that he could serve as a judge of the dead in the underworld. A distinct tradition in which he was regarded either as a god of equal status as the usual heads of the Mesopotamian pantheon, Enlil and Anu, or as a king of the gods in his own right, is also attested, though it only had limited recognition. In Mesopotamian art, his symbol was the crescent. When depicted anthropomorphically, he typically either wore headwear decorated with it or held a staff topped with it, though on kudurru the crescent alone serves as a representation of him. He was also associated with boats.

The goddess Ningal was regarded as Sin's wife. Their best attested children are Inanna (Ishtar) and Utu (Shamash), though other deities, for example Ningublaga or Numushda, could be regarded as members of their family too. Sin was also believed to have an attendant deity (sukkal), Alammuš, and various courtiers, such as Nineigara, Ninurima and Nimintabba. He was also associated with other lunar gods, such as Hurrian Kušuḫ or Ugaritic Yarikh.

The main cult center of Sin was Ur. He was already associated with this city in the Early Dynastic period, and was recognized as its tutelary deity and divine ruler. His temple located there was known under the ceremonial name Ekišnugal, and through its history it was rebuilt by multiple Mesopotamian rulers. Ur was also the residence of the en priestesses of Nanna, the most famous of whom was Enheduanna. Furthermore, from the Old Babylonian period onward he was also closely associated with Harran. The importance of this city as his cult center grew in the first millennium BCE, as reflected in Neo-Hittite, Neo-Assyrian and Neo-Babylonian sources. Sin's temple survived in later periods as well, under Achaemenid, Seleucid and Roman rule. Sin was also worshiped in many other cities in Mesopotamia. Temples dedicated to him existed for example in Tutub, which early on was considered another of his major cult centers, as well as in Urum, Babylon, Uruk, Nippur and Assur. The extent to which beliefs pertaining to him influenced the Harranian Sabians, a religious community who lived in Harran after the Muslim conquest of the Levant, is disputed.
