The “Book of Giants” is a significant work associated with Mani, the founder of Manichaeism, a gnostic religion that was once widespread but is now extinct. The book is part of the Manichaean literature and is mentioned as a canonical work in various sources, including the Coptic Kephalaia, Homilies, Psalms, and even in a Chinese compendium of Mani’s teachings.
 
The text relates to ancient Jewish traditions, specifically the giants mentioned in the Book of Enoch, and incorporates these narratives into Manichaean mythology. It details the primeval events of a great battle among giants and explores themes of cosmogony and epic battles.
 
The “Book of Giants” has been found in various languages, including Middle Persian, Sogdian, and Old Turkish, indicating its importance in the East Manichean tradition. Unfortunately, the original Aramaic text has not survived, but fragments have been discovered in several collections around the world.
 
For those interested in ancient texts and the intersection of different cultural mythologies, the “Book of Giants” offers a fascinating glimpse into the religious and mythological syncretism that characterized Manichaeism.
