I am curious as to whether Post-Seleucid Persian civilisation forgot about their Achaemenid forebears. I wonder this due to the lack of clear references pertaining to Cyrus' dynasty dated after the fall of his empire. The Sassanids did not trace their empire back to that of the Achaemenids but rather the mythical Kayanids and, despite the attempts of later scholars, the attribution of the Kayanids as a "mythologised" version of the House of Achaemenes is a rather hard pill to swallow. The names, the dates, and the feats of the Kayanid heroes do not square at all well with what we know of the Achaemenids, and I feel it is safe to say that there is no connection between the two houses.
So why was Sassanian historiography so poor as to ensure the Achaemenids were all but erased in the cultural memory of the Persian people? The Sassanids managed to piece back together other aspects of their past—such as the destruction wrought by Alexander the Great (or "the Accursed" as the Persians would know him), and the religion of Zoroastrianism. It's thought that the Sassanids relied upon Babylonian records for much of this historical reconstruction (the Magus class having been defanged and rendered ignorant under Macedonian rule). If the memory of Alexander survived so strongly as to affect the Persian national consciousness for centuries to come (I believe the Sassanids believed the Macedonian king was a Roman, casting the rivalry between the two powers as an existential struggle that had been waged since the beginning of time), then why can the same not be said of Cyrus or of Darius? How could the Sasanians remember only half of their history?
Indeed, Ferdowsi's Shahnameh uses the conquest of Alexander as the liminal threshold between the mythical period of the Kayanians and the historical rule of the Sasanians. Where are the Achaemenids? Where are the Seleucids? Why are the Parthians barely mentioned?
