The Book of Enoch is an ancient Hebrew religious text attributed to the great-grandfather of Noah. It describes the life of Noah, his family, and the events that led to his death. In a nutshell, it's a story of the origin of the world. The story of Enoch's descent, which is told in the biblical account of the Flood, is based on the story of his death.
The first thing you should know about O Livro de Enoque is that it was written by a man named Enoque, who lived about six generations before Adao and Diluvio. While the writings of Epimenides have a lot of scholarly value, they are not authoritative. While Paul cites Epimenides in Titus 1:2, it doesn't necessarily mean that we should add authority to the works of Enoque. Judas' citation of the O. Livro de Eloque in verses 14-15, for example, is a possible example of a possible connection.
In a nutshell, O Livro de Enoque is a book of apocalyptic prophecies. It details the end of the world, a giant caniba, and the rebirth of the world after the diluvio. O Livro deEnoque was translated into Greek by Jorge Sincelo, who argues that it contains a number of ambiguities.
