Epic heroes are noble individual of prodigious martial strength but they too mostly pass through several trials to prove their legitimate position. These endeavors include battles with evils while the heroes rarely overcome mental evils. The trials are challenging for heroes’ power to defeat the evil. The seven trials of Rostam and Isfandiyār as well as the twelve trials of Heracles fall in this category. Twelve thousand years of the Zoroastrian world includes an eternal battle between good and evil and the good will win this battle at last in the Armageddon. Zoroaster is the highest level of Ahura Mazda’s forces against Angra Mainyu. He too passed the seven trials in his childhood and adulthood which is not though the pure history but mixed with the myths and epics. Therefore, he acts as a hero to prove his legitimacy and triumph over dēws, Karaps and evil thoughts was his utmost aim and established Zoroastrianism through converting Goštāsp and his court. All of the trials he passed proved his legitimacy for being the prophet.
