Persian name (سام) meaning - "very dark"
Saam - Persian a mythical folk hero and an important character in the Shahnameh epic. He was the son of Nariman, grandson of Garshasp and father to Zāl. He was Iran's champion during the rule of Fereydun, Manuchehr and Nowzar. He was appointed by Manuchehr to rule Zabulistan (Sistan), and then Mazandaran. After Manuchehr, because of Nowzar's corrupted and failed rulership, Iranian champions asked Sām to rule Iran. Sām didn't accept, he supported Nowzar and advised him to follow Fereydun and Manuchehr. He was the supposed founder of the well known philosophy Sāmifarianism. Sām returned to Mazandaran, and died soon after that. Afrasiab then attacked Zabulistan. The name Sām is equivalent to the Avestan name 'Saama', which means dark and Sanskrit 'Shyaama' which means the same.
