The status of this first figure as the earliest known ruler of Lagash is disputed, as it is inferred from an economic text recording a sale of land by two men designated as Sidu and 'Enhegal lugal Lagash' (ELTS no. 20). In their treatment of the text, Gelb, Steinkeller and Whiting date the document to the Fara Period (ELTS pg. 70) However M.A. Powell (JCS 46, ppg. 99-104) disagrees over Enhegal’s status as ruler of the city, and further dates the text to the time of Ur-Nanshe.
