The Manichaean version is similar to the one found in Qumran, only adapted to Mani’s story of the cosmos. The fallen angels are here archontic demons escaped from their prisons in the sky, where they were placed when the world was constructed. They would have caused a brief revolt, and in the process, two hundred of them escaped to the Earth.21 While most given names are simply transliterated into Iranian language, Ohyah and Hahyah are renamed Sam and Nariman.
