(NHC VII, 1)

A Gnostic apocalypse in which ascends to heaven and is given extensive revelations by a divine being called Derdekeas. Its title is given at the beginning of the tractate. The revelations consist of a cosmogony, an anthropology, and a history of salvation. The cosmogonic myth reflects a system of three principles: Light, Darkness, and Spirit.

There are no obvious Christian features in the text. A somewhat similar system, though in a Christian dress, is found in a treatise called The of Seth, discussed by Hippolytus in his account of the doctrine of certain Sethians. Extant only in Coptic, was originally composed in Greek, probably in late third-century Syria.
