Mount Damavand
In the "Avestā", Thraetaona is the son of Aθβiya, and so is called "Āθβiyāni", meaning "from the family of "Aθβiya"". Originally, he may have been recorded as the killer of the dragon Zahhak ("Aži Dahāk"), but in Middle Persian texts, Dahāka/Dahāg is instead imprisoned on Mount Damavand in Amol.
