(A 12th century Latin version of a book, which survived hidden in libraries in Italy and France after the Inquisition. It talks about Satan (Sathanas) gaining control over a number of lower heavens (but not the seventh, ruled over by Rex Caelorum), and then creating Adam and Eve out of matter (earth), and forcing two angels to be inside of their material bodies in order to provide the physical bodies of clay with living souls. Then Sathanas, in the form of a Serpent, causes lust to fall over Adam and Eve, and Sathanas penetrates Eve with the Serpent's tail, and causes Adam and Eve to produce serpents and Satanic offspring (human beings).
