The apocryphal Book of Enoch claims to be revelations of Enoch, transcribed by him and entrusted to be preserved for future generations by his son, Methuselah. In this book, Enoch recounts two visions he has had to Methuselah. The first is about the Genesis flood narrative, and the second chronicles the history of the world from Adam to the Last Judgment. In the latter vision, men are represented as animals - the righteous are white cattle and sheep, the sinners and enemies of Israel are black cattle and wild animals. Following his father's death in the Book of Enoch, Methuselah is designated by God as a priest, while Methuselah's grandson, Noah's brother Nir, is designated by God as his successor.
