Absu

“The Underworld in ancient Sumer was known by many names, among them ABSU or “Abyss”, sometimes as Nar Mattaru, the great Underworld Ocean, and also as Cutha or KUTU as it is called in the Enuma Elish (the Creation Epic of the Sumerians). The phonetic similarity between Cutha and KUTU and Chthonic, as well as Cthulhu, is striking. Judging by a Sumerian grammar at hand, the word KUTULU or Cuthalu (Lovecraft’s’s Cthulhu Sumerianised) would mean “The Man of KUTU (Cutha); the Man of the Underworld; Satan or Shaitan, as he is known to the Yezidis (whom Crowley considered to be the remnants of the Sumerian Tradition). The list of similarities, both between Lovecraft’s creations and the Sumerian gods, as well as between Lovecraft’s mythos and Crowley’s magick, can go on nearly indefinitely, and in depth, for which there is no space here at present.”
