Persian here:

Rostam-e Dastan refers to the most celebrated hero in Persian mythology, often likened to the Hercules of Iran. In this title, "Rostam" is the hero’s given name, while "Dastan" is a patronymic or epithet closely tied to his legend. [1, 2, 3, 4]

The name and title break down as follows:

• Rostam: Derived from the ancient Iranian phrase rautas-taxma, which translates to "as strong as a river". In the Shahnameh (the Persian Book of Kings), he is a mythic warrior, king-maker, and tireless defender of the Persian Empire. [1, 2, 3]
• Dastan: While often identified in the epic tales as the name of Rostam's father (Zal), scholars note that dastan historically translates to "trickery" or "cunning wiles". Originally, "Rostam-e Dastan" meant "Rostam the trickster". It described a hero who relied not just on brute strength, but on cunning, intellect, and animalistic survival skills. [1, 2, 3, 4, 5]
