Following the flight of Bahram Chubin, Khosrow Parviz entered the battlefield where the fate of Iran had been decided. He distributed the captured spoils—purses of gold and rich crowns—among his triumphant warriors. Mounting a swift steed, he rode until he reached a desolate, thorny field, where he dismounted and cast himself upon the dust before the Almighty. In deep humility, the Sasanian King praised God for purging the realm of his fierce adversary and granting victory to the rightful crown.
Returning to his royal pavilion, Khosrow summoned his scribe to draft a grand letter upon fine silk to Caesar of Rome. He recounted the divine favor shown at Adhar Gushnasp, the fierce clashes, the sudden collapse of Bahram's host, and the burning of the enemy camp. Sealed with the imperial emblem, the message was dispatched across the borders to Rome.
Upon receiving the letter, Caesar stepped down from his throne in reverence, giving thanks to the Creator who guides all mortals and bestows victory. He distributed vast wealth and food to the poor, and penned a noble response filled with cosmological wisdom, exalting the Sovereign of the sun, moon, elephant, and ant. Along with his letter, Caesar sent unmatched imperial treasures: an ancient Roman crown, regal collars and earrings, one hundred and sixty gold-inlaid robes, thirty camel-loads of dinars and precious gems, a jewel-encrusted cross, a magnificent throne, and a green tunic woven with golden threads, accompanied by four esteemed Roman philosophers.
Khosrow welcomed the Roman embassy with an escort of one thousand noble horsemen. Yet, upon examining the gifts, he hesitated before the Christian robe adorned with the sign of the cross. Weary of geopolitical fallout, he pondered whether rejecting the garment would alienate Caesar, while wearing it might cause his Zoroastrian nobles to accuse him of apostasy for the sake of wealth. His trusted advisor assured him that true faith lies within the soul, not in outward vestments, and that wearing the robe would honor the alliance without breaching his devotion to Zoroaster. Thus, Khosrow donned the cross-adorned garment and set the crown upon his head, leading the wise to recognize a masterstroke of diplomacy, even as the ignorant rumored that the King of Kings had secretly embraced the Christian faith.
