The investigation of name and title of Farayin/Shahrbaraz in Shahnameh and other historical sources

In Sassanid section of Shahnameh Ferdowsi names of many historical characters are mentioned, yet they are otherwise recorded and at times appear somewhat altered in other sources, or rather their epithets and formal titles sit in place of their names.  Sometimes this difference is so large that could mislead a researcher in arriving at the true etymology, meaning of the name and genealogy of the character and hence lead to greater scientific fallacies.  Certain names or epithets employed in Shahnameh are unique and are not seen in other sources.  Farayin, name or epithet of Shahrbaraz is mentioned in none of the historical sources but Shahnameh.  This research deals with the etymology and examination of this name or epithet in different ancient sources such as Pahlavi, Farsi, Arabic, Aramaic, Syriac and Greek ones. The reason why Ferdowsi had selected and recorded Farayin and whether or not this name is true, also Ferdowsi’s role, his source, his scribers and editors and their possible role in alteration of the name are further discussed.  Goraz and Farayin, being one person exist in Shahnameh and Ferdowsi had used the two with slight modification.
