Geshtu-E

Ilawela (formerly variously transcribed as Geshtu-(E), Geshtu, Gestu, or We-ila) is, in Sumerian and Akkadian mythology, a minor god of intelligence. In the Atra-Hasis Epic he was sacrificed by the great gods and his blood was used in the creation of mankind:

"Ilawela who had intelligence, They slaughtered in their assembly. Nintu mixed clay With his flesh and blood. They heard the drumbeat forever after. A ghost came into existence from the god’s flesh, And she (Nintu) proclaimed it as his living sign. The ghost existed so as not to forget (the slain god). […] You have slaughtered a god together with his intelligence. I have relieved you of your hard work. I have imposed your load on man."
