A myth covering the reason why Inanna abandons the city to its fate. There is a book somewhere - The Curse Of Agade by j Cooper, Baltimore, the John Hopkins University Press, 1973.
Summary: Upon the fall of the kingdom of Akkad, the city of Akkad was destroyed and so thoroughly devastated that it was never rebuilt. Historical reality brought a serious question of theodicy: if Inanna so loved the kings of Akkad, how could she let this happen? This question is dealt with in this myth, a historio-graphic tale written during the Ur III dynasty. In this text Inanna, the patroness of Agade, provisions the city with riches, endows its elders with counsel, gives its maidens dancing grounds, its young men martial might, its children joy. Suddenly, Enlil, brings the matter of the Ekur (Enlil's temple in Nippur) on a peaceful Agade; no warning is given, no eplanation is offered. Inanna grows uneasy and abandons her temple. As she leaves, she, the spirit of battle and fight, takes these qualities out of the city. Later, after King Naramsin commits a sacrilege against Nippur and Ekur, Enlil brings barbarians to devestate the city, and all the great gods (including Inanna) curse the Akkad.
