Davāzdah Rokh[1] (Persian: دَوازدَه رُخ) (Twelve combats) is a story in Shahnameh. This relatively long story (almost 2,500 verses) is described as one of the finest stories of Shahnameh in terms of "plot, dramatic description, and insight into human nature".[1]
It takes place on the border between Iran and Turan, where a number of Iranian heroes fight with a number of Turanian heroes. In all cases, Iranian heroes defeat their Turanian competitors. Goudarz is the chief of Iranian heroes and Piran Viseh is the chief of Turanian heroes. The battle begins when Piran's brother, Houman, challenges the Iranians and is killed by Bizhan in a single combat. The two armies then join battle, without either side prevailing. Finally they agree to abide by the outcomes of a series of single combats (mard o mard) between the greatest heroes of the two armies:
In all battles, the winner is the Iranian hero. At the end, Goudarz kills Piran and the war ends. However, Gostaham, who has not been chosen by Kay Khosrow to fight with Turanians, chases Lahhāk and Faršēd, brothers of Piran, and kills them, although he himself is severely injured in the process, whereupon Bizhan takes him to Kay Khosrow, who saves his life by the expedient of binding a healing amulet to his arm. The war ends with the death of Afrasiab, Turan's king. In some manuscripts of Shahnameh the story is entitled az Yazdah Rokh (Eleven combats), not counting the last fight between Gostaham and Piran's brothers.
The campaign ends with the victory of Iran and the implementation of a festival in honour of the empire’s noble ruler Kai Khosrow and Goudarz the valiant commander of his sovereign’s army.
