A. Sutherland – AncientPages.com – According to surviving clay tablet, dated by the scribe who wrote around 2125 BC during the reign of King Utukhegal of Erech (Uruk), we read that:
After the Flood, a dramatic and devastating event, the kingship had descended from heaven, and Kish became the seat of kingship. In Kish, twenty-three kings reigned 24,510 years, three months, 3 1/2 days. When Kish was defeated, its kingship was carried off to Eanna.
In Eanna (the name of the temple of Inanna in Uruk) we meet, Meskiaggasher, the son of the sun god Utu, who reigned as En (Priest) and Lugal (King) for 324 years.
We do not know precisely what his role was in Uruk, but he would have been the master and guardian of the fortress around which his son would have built the city of Uruk, and the temple became the main shrine of the goddess.
