as ancestors in the legendary Sasanian family tree show the existence of an inclination toward the Achaemenids in the early Sasanian period. There are many proofs in Middle Persian and Arabic-Persian writings that show the Sasanians' aggressive confrontation with Rome in order to return to the magnificent past status in the west and it had been assumed that the glory was taken by the Romans. About that, Al-Tabari has mentioned that Ardashir claimed and announced that he had risen to take the revenge of Darius III, who had been defeated and killed by Alexander III of Macedon. Roman historians like Herodian and Cassius Dio have also mentioned reports about "the Sasanians' desire to return to the magnificence and kingdom of the Achaemenids"; these reports of Roman historians show that the Romans had understood the goals of the Sasanian foreign policy well; though they did not have a decent understanding of the change and transformation in the royal Iranian continuum. The place of Alexander, who was known as a nemesis of Iran, in the thought of the Sasanians' desire for return at the time was simultaneous and aligned with the idea of "following and honoring Alexander" in the Roman emperors; Caracalla called himself "the second Alexander" and "Severus Alexander" honored him. Kettenhofen, Robin and Heuse believe that the class of Greek-Roman sources that have reported the Sasanians' familiarity with the Achaemenids and their desire for return to and extension of the Achaemenid lands had propagative applications and should be interpreted in the frame of the Roman empire thoughts. But what is clear is Ardashir's and later his son Shapur's claim of Roman lands. Daryee believes that the cause of Ardashir and Shapur's wars with Rome was to accommodate their territorial ideals with traditions; he believes that the Sasanians' claim of Asian lands as their fathers' legacy had a mythical basis and originated from the mythical story of Fereydun dividing the world between his sons (Salm, Tur and Iraj); in that myth, Fereydun grants the reign of Turan to Tur and Rome to Salm and Iran, which is the best land in the world, to Iraj; the brothers become envious of the latter and the world goes under war. Thus, the Sasanians considered themselves Iraj's children and the Romans Salm's heirs by a mythical view. Daryee adds that only by that way the Sasanians' territorial claims, which are mentioned in Cassius Dio
