Zahaak

Aži Dahāka is the most significant and long-lasting of the ažis of the Avesta, the earliest religious texts of Zoroastrianism. He is described as a monster with three mouths, six eyes, and three heads (presumably meaning three heads with one mouth and two eyes each), cunning, strong and demonic. But in other respects Aži Dahāka has human qualities, and is never a mere animal. Dahāg is said to have ruled for a thousand years, starting from 100 years after Jam lost his Khvarenah, his royal glory (see Jamshid). He is described as a sorcerer who ruled with the aid of demons, the daevas (divs).
