Inzak (Akkadian Inzak; Sumerian Enshag; older scholarship Enshag, also Enzag, Enzak, Anzak) was the principal god of Bronze Age Dilmun, the civilisation centred on Bahrain and the Eastern Arabian coast including the island of Failaka, anciently called Agarum. He is first named in a late third-millennium inscription of Gudea of Lagash, where, under the form Ninzaga, he ships copper to Lagash, reflecting Dilmun's role as the entrepot of the Gulf copper trade. The Dilmunite kings, attested on the Durand Stone of Bahrain and on stone vessels from royal tumuli (the dynasty of Rimum and his son Yagli-El, c. 1780 BCE), styled themselves 'servant of Inzak of Agarum', a theocratic royal ideology comparable to that of Assur and Eshnunna. In the Sumerian paradise myth 'Enki and Ninhursaga', set in Dilmun, Enshag is the eighth of the deities the mother-goddess Ninhursaga creates to cure Enki, and is rewarded with the lordship of Dilmun. His cult, shared with the goddess Meskilak, was housed in the Failaka temples (Ekarra, 'house of the quay', and Egal-Inzak, 'palace of Inzak'). His worship reached beyond Dilmun: Enzak stood in a divine triad on the Susa acropolis in the eighteenth century BCE, and in the late god-list An = Anu sha ameli he was equated with the Babylonian scribal god Nabu.
