In several respects, for instance in Goshtasb's/Goshtasf's (etc) mythological genealogy, the Sistan cycle texts continue the Zoroastrian tradition. So, for example, Goshtasp is identified as a member of the Kayanian dynasty, is the son of Lohrasp/Lohrasb (etc), is the brother of Zareh/Zarer (etc), is the father of Esfandiar/Isfandiar (etc) and Bashutan/Beshotan (etc), and so on. However, in the Sistan legends, Goshtasb/Goshtasf (etc.) is an abominable figure, altogether unlike the hero of Zoroastrian tradition. The reason for this discrepancy is unknown. According to the Sistan tradition, Goshtasb demands the throne from his father Lohrasp, but storms off to India ("Hind") when the king declines. Goshtasb's brother Zareh (Zareh/Zarer etc., Avestan Zairivairi) is sent to fetch him, but Goshtasb flees to "Rome" where he marries Katayoun (Katayun/Katayoun etc), the daughter of the 'qaysar'. Goshtasb subsequently becomes a military commander for the Roman emperor, and encourages the emperor to demand tribute from Iran. Again Zareh is sent to fetch Goshtasb, who is then promised the throne, and is thus persuaded to return.
