The Lost One
outhouse said:In Sumerian and Babylonian mythology, Adamu was the first man. The gods tricked Adamu and his descendants out of immortality - not wanting man to be immortal like the gods - by telling him that the magic food of eternal life was poisonous to him, and as such Adamu didn't eat it and so didn't become immortal.
Ok, I think I know who you are talking about. I have not read everything, and I still trying to piece together all the myths (and literature).
I know of the Akkadian/Babylonian Adapa, one of the 7 sages. Adapa was a favorite of Ea (Enki), but this god tricked him from eating the food of Anu, that would have made him immortal.
Perhaps this Adapa is the same as your Sumerian Adamu.
