Jushur

Jushur (also transliterated Jucur, Gushur, Ngushur, Gishur, etc.; earlier read as Gaur), according to the Sumerian king list, was the first king of the first dynasty of Kish. It claims he reigned in Sumer for 1,200 years as the first post-diluvian king.
"After the flood had swept over, and the kingship had descended from heaven, the kingship was in Kish."
No archaeological evidence corroborating his existence or identity has been found. If a historical figure, he may thus mark the beginning of the Early Dynastic Period of Sumer, corresponding very roughly to the Early Bronze Age II.
