The First and Second Books of Adam and Eve, also known as The Conflict of Adam and Eve with Satan, are a late Christian work dating hundreds of years after the actual Biblical Scriptures. The First Book of Adam and Eve tells the story of what happened to Adam and Eve after they left Eden. It tells of the difficulties they encountered in their new home known as the Cave of Treasures, and of Satan's many appearances (often mistranslated as "apparitions") to them. The First Book of Adam and Eve also chronicles the birth of Cain and his twin sister Luluwa and of Abel and his twin sister Aklemia. It also details Cain's murder of Abel, as well as Adam's death. The first book focuses on Adam's sorrow at being outside the Garden of Eden. Adam and Eve are constantly plagued by visits from Satan, who appears to them in many forms and attempts to trick them over and over again. The Second Books of Adam and Eve is an account of the history of the patriarchs who lived before the Flood. It chronicles the lives of Seth's descendants on the Holy Mountain and tells how they broke God's commandment and left the mountain, being tricked by Cain's descendants. The First and Second Books of Adam and Eve are classed as pseudegraphica which means "false works." The books are thought to have their source in the fifth or sixth century CE, but they show evidence of extensive and much later Christian additions from after the time of Middle Ages.
