Book of the Giants of Mani should include not only the story of defeat and imprisonment of 200 demons by /4 angels, but also the story of the creation of human by demons saqlun and Pesus. The story of 200 demons and /4 angels may originate from the Jewish Book of Enoch. And the story of demon saqlun may come from The Apocalypse of Adam, The Gospel of the Egyptians, The Apocryphon of John and The Hypostasis of the Archons in The Coptic gnostic library.
