After Dara was laid to rest with full monarchical rites, Alexander summoned a swift scribe, ordering him to prepare a Chinese reed pen and Roman silk paper. The scribe dipped his pen and set down a royal decree from Alexander to the mother of Roshanak. In this epistle, the conqueror praised Yazdan and reflected on the fickle wheel of fate, recounting how Dara had fallen by the hand of a traitorous servant despite Alexander’s prior entreaties for peace. He mused that death strikes like an autumn wind, sweeping mortals away like dry leaves. He reminded her that the realm now stood beneath his rule, yet he was bound by Dara’s dying request: the fallen king had betrothed his daughter Roshanak to Alexander so she might reign at his side. Alexander requested that Roshanak be dispatched to his court with regal pomp, accompanied by her nurses, attendants, Persian nobles, and led by the high Mobad of Isfahan. He reassured her that the governance of Isfahan and the officers appointed by Dara would remain unchanged and governed by justice.
Thereafter, Alexander dictated a second letter directly to Roshanak. Opening with praises for the wise Creator, he wrote that only noble, pious, and soft-spoken souls spring from the seed of royalty. He informed her that her father had entrusted her hand to him before his passing. He called upon her to take her rightful place as the supreme lady of his royal house, to adorn the ivory throne, and wear the crown of queenship. He bade her travel with a serene spirit and modesty, assuring her of her elevated stature. Once the missives were sealed, a philosopher swift as the wind departed to carry the king's decrees.
