One early inscription for an "Elulu (or Elili), king of Ur" was found at nearby Eridu, stating that this king had built up the abzu ziggurat for Enki.<ref>Sollberger, Edmond, and Jean-Robert Kupper, "Inscriptions royales sumeriennese akkadiennes", Littératures Anciennes du Proche-Orient 3, Paris: Les Éditions du Cerf, 1971</ref>
Some scholars have further connected Elulu with the "Elilina" who was said to be the father of the later king Enshakushanna of Uruk, but this theory is uncertain, owing to chronological difficulties. The inscription states that Enshakushanna's father was "Elilina", possibly King Elulu of Ur:<ref>Template:Cite book</ref>
