The Arzhang is the holy book of Manichaeism, written and illustrated by its prophet Mani. The book has been lost and its content is unknown. However, it is known that its illustrations were of appreciable quality, and copies were preserved in the Middle East as late as 1092 C.E., when it is recorded that the library of Ghazni held a copy. Manichaeism was one of the major ancient religions. ...
In 1904, expeditions to Iran from England brought back some fragments of Manichaean holy texts, which were published as The Book of the Giants.
