In short: Long before the Manichaean tradition adopted it, the Book of Giants circulated among Second Temple Jewish sects. This apocryphal narrative expands on the Genesis account of the Watchers and their hybrid offspring, offering a dark, mythological justification for why God felt compelled to cleanse the earth with a flood.

The Book of Giants centers on the Watchers, divine beings who descended to earth to instruct humanity but instead violated creation's boundaries by mating with human women. Their offspring, the giants—variously termed nephilim, gibborim, or rephaim—wrought destruction through violence, sexual debauchery, and the revelation of forbidden heavenly secrets. The text portrays these giants as a corrupt, half-breed race that ultimately forced God to intervene.

The work's history is complex, spanning centuries and cultures. While once thought to be a Manichaean composition attributed to Mani, who lived from about AD 216 to 274, the 1948 and 1971 discoveries of Aramaic fragments among the Dead Sea Scrolls at Qumran proved the text existed much earlier. Scholars now date its composition to at least the 3rd century BC. The Qumran community clearly valued these Enochic traditions, as evidenced by the ten distinct manuscripts identified by Loren Stuckenbruck across four different caves.

The narrative follows the prophet Enoch as he intercedes for the giants, who seek mercy after receiving prophetic dreams of judgment. Enoch provides them with tablets detailing God's coming wrath, but many giants choose defiance over repentance. Later, the Manichaean version adapted these themes, renaming the giant brothers Ohyah and Hahyah as Sam and Nariman, and framing the conflict as a cosmic battle between the forces of Light and demonic archons.

Despite its early influence, the book eventually fell into obscurity. By the fourth century, influential figures like Hilary, Jerome, and Augustine banned the work, partly due to its association with the Manichaeans and its perceived strangeness by Hellenistic scholars. It remained largely lost to Western Christendom until the twentieth-century archaeological finds in Xinjiang Province and the Judean Desert finally brought these ancient, fragmented accounts back into the light of modern scholarship.
