In ancient Iran’s mythic frame of mind, power rotation in kings’ hands was rationalized with concepts based on racial and blood bonds such as the Light of God. However, in Shahnameh, a character like Zahhak became a king without possessing the privilege of the Light of God. Also, in the same epic, some characters became popular at least for a limited period without the grace of the Light of God. As an important character in Ferdowsi’s epic, Kaveh the Blacksmith is known as a charismatic person in Iranians’ collective memory without enjoying the Light of God. Employing an analytic-descriptive approach and benefitting from the library and electronic resources, the current essay seeks to scrutinize Kaveh the Blacksmith’s deeds in Shahnameh and match these deeds in other Iranian epic and historical works to detect the mythic and historical identity of Kaveh the Blacksmith. Specifically, it deals with the roles and functions of charisma and anti-charisma in Kaveh the Blacksmith and other characters related to him. By reading Kaveh’s character based on Marx Weber’s charismatic authority, the essay concluded that although Kaveh had a charismatic character, he did not have charismatic authority. Kaveh was not solely a fighter against Zahhak’s government, he could oppose Fereidon and Jamshid because he rebelled against the authorities to establish justice, thus, Kaveh had an anti-charismatic character in a clash with any type of charismatic power
