The story of
Memorial of Zarēr plays in the time of the mythological
Kayānid monarch Wištāsp (< Avestan
Vištāspa), the patron of
Zoroaster. The story opens with the arrival of messengers at the Wištāsp's court. The message is from the
Daēva-worshipping king of the
Un-Iranian Xyonites (< Av.
x́yaona-),
Arjāsp ( Middle Persian
Arzāsp < Avestan
Arəjaṱ.aspa), who demands that Wištāsp "abandon 'the pure Mazdā-worshipping religion which he had received from
Ohrmazd', and should become once more 'of the same religion'" as himself. Arjāsp threatens Wištāsp with a brutal battle if Wištāsp does not consent. Zarēr, who is Wištāsp's brother and the command-in-chief of Wištāsp's army, pens a reply in which Arjāsp's demands are rejected and a site for battle is selected. In preparation for battle, the army of the
Iranians grows so large that the "noise of the caravan of the country of Iran went up to heavens and their clamors went down to hell." Wištāsp's chief-minister, Jāmāsp (< Av.
Jāmāspa), whom the poem praises as infinitely wise and able to foretell the future, predicts that the Iranians will win the battle, but also that many will die in it, including many of Wištāsp's clan/family. As predicted, many of the king's clansmen are killed in the fight, among them Wištāsp's brother Zarēr, who is slain by Wīdrafsh / Bīdrafsh, the sorcerer (the
epithet is
jādūg, implying a practitioner of wicked magic) of Arjāsp's court. Zarēr's 7-year-old son, Bastwar / Bastūr (< Av. Basta.vairi) goes to the battlefield to recover his father's body. Enraged and grieving, Bastwar vows to take revenge. Although initially forbidden to engage in battle due to his youth, Bastwar engages with the
Xyonites, killing many of them, and revenging his father by shooting an arrow through Wīdrafsh's heart. Meanwhile, Bastwar's cousin
Spendyād (< Av.
Spǝṇtōδāta) has captured Arjāsp, who is then mutilated and humiliated by being sent away on a donkey without a tail. ==Legacy==
