Another source of Mani's scriptures was original Aramaic writings relating to the "Book of Enoch" literature (see the Book of Enoch and the Second Book of Enoch), as well as an otherwise unknown section of the Book of Enoch called "The Book of Giants". This book was quoted directly, and expanded on by Mani, becoming one of the original six Syriac writings of the Manichaean Church. Besides brief references by non-Manichaean authors through the centuries, no original sources of "The Book of Giants" (which is actually part six of the Book of Enoch) were available until the 20th century.
