Ahrimanes

Ahrimanes: The name given to the Chief of the Cacodaemons, or fallen angels by the Persians and Chaldeans.  These Cacodaemons were believed to have been expelled from Heaven for their sins; they endeavoured to settle down in various parts of the earth, but were always rejected, and out of revenge they find their pleasure in injuring the inhabitants.  Xenocritus thought that penance and self-mortification, though not agreeable to the gods, pacified the malice of the Cacodaemons.  Ahrimanes and his followers finally took up their abode in all the space between the earth and the fixed starts, and there established their domain, which is called Arhiman-abad.  As Ahrimanes was the spirit of evil his courterpart in Persian dualism was Ormuzd, the creative and benevolent being.
