Zahhak

Zahhāk or Zahāk (pronounced [zæhɒːk]) (Dari: ضحّاک), also known as Zahhak the Snake Shoulder (Persian: ضحاک ماردوش, romanized: Zahhāk-e Mārdoush), is an evil figure in Persian mythology, evident in ancient Persian folklore as Azhi Dahāka (Persian: اژی دهاک), the name by which he also appears in the texts of the Avesta. In Middle Persian he is called Dahāg (Persian: دهاگ) or Bēvar Asp (Persian: بیور اسپ) the latter meaning "he who has 10,000 horses". In Zoroastrianism, Zahhak (going under the name Aži Dahāka) is considered the son of Ahriman, the foe of Ahura Mazda. In the Shāhnāmeh of Ferdowsi, Zahhāk is the son of a ruler named Merdās.
