Book of the Secrets of Enoch

The Book of the Secrets of Enoch was preserved only in the Slavonic tongue and was thought lost until 1892. Even when rediscovered it was thought that this text was just another version of the Ethiopic Book of Enoch; but the Secrets of Enoch is an entirely new pseudepigraph and not a version of the well-known Book of Enoch. It seems to have been translated from a lost Greek original and was written by a Coptic Jew in Alexandria during the earliest period of the Christian era.
