The Second book of Adam and Eve

Books 1 and 2 begin immediately after the expulsion from the Garden of Eden, and end with the testament and translation of Enoch. Great emphasis is placed in Book 1 on Adam's sorrow and helplessness in the world outside the garden.

In Book 2, the "sons of God" who appear in Genesis 6:2 are identified as the children of Seth, and the "daughters of men" as women descended from Cain, who successfully tempt most of the Sethites to come down from their mountain and join the Cainites in the valley below, under the instigation of Genun, son of Lamech. This Genun, as the inventor of musical instruments, seems to correspond to the Biblical Jubal; however he also invents weapons of war. The Cainites, descended from Cain the first murderer, are described as exceedingly wicked, being prone to commit murder and incest. After seducing the Sethites, their offspring become the Nephilim, the "mighty men" of Gen. 6 who are all destroyed in the deluge, as also detailed in other works such as I Enoch and Jubilees.

Books 3 and 4 continue with the lives of Noah, Shem, Melchizedek, etc. through to the destruction of Jerusalem by Titus in AD 70. The genealogy from Adam to Jesus is given, as in the Gospels, but including also the names of the wives of each of Jesus' ancestors, which is extremely rare.
