Zahhak return (ضحاک ماردوش)

Ahriman kissed King’s (Zahhak) shoulders and disappeared. Two black
snakes appeared where Ahriman’s lips had touched. The snakes could not be removed, as
new ones would replace them as soon as they were cut off. All physicians and healers in
the realm proved powerless to deal with the snakes. Ahriman appeared in court as a
skilled physician and prescribed a young human brain to be fed daily to each snake to
keep Zahhak safe from them. Ahriman, hateful of human happiness, had prescribed
murdering all mankind.
He was bound and taken to a cave under Mount Damavand, where he was imprisoned in chains. Fareydun thereafter proceeded to erase all traces of Zahhak’s tyranny.
