Zahhak, The Ancient Iranian Dragon

By Juliano Zasso (1833-1889) - Armenian History in Italian Art.

Zahhāk or Zohhāk is an evil figure in Iranian mythology, evident in ancient Iranian folklore as Aži Dahāka (Azh dahak), the name by which he also appears in the texts of the Avesta. In Middle Persian he is called Dahāg or Bēvar-Asp, the latter meaning "[he who has] 10,000 horses".

Within Zoroastrianism, Zahak (going under the name Aži Dahāka) is considered the son of Angra Mainyu, the foe of Ahura Mazda.
