An = Anum, also known as the Great God List,[1][2] is the longest preserved Mesopotamian god list, a type of lexical list cataloging the deities worshiped in the Ancient Near East, chiefly in modern Iraq. While god lists are already known from the Early Dynastic period, An = Anum most likely was composed in the later Kassite period.
While often mistakenly described as a list of Sumerian deities and their Akkadian equivalents, An = Anum is focused on presenting the familial relationships between deities, as well as their courts and spheres of influence. The first four tablets list the major gods and goddesses (Anu, Enlil, Ninhursag, Enki, Sin, Shamash, Adad and Ishtar) and their courts, arranged according to theological principles, but tablets V and VI do not appear to follow a clear system, and tablet VII is a late appendix listing the names of Marduk and one of his courtiers.
Many other works of ancient scholarship were influenced by An = Anum, including a similar list of temples and various theological commentaries. It has also been proposed that it was the basis for the remodeling of the pantheon of Uruk in the Seleucid period.
