At the dawn of the next day, Khosrow Parviz ascended the Kayanid throne and placed the imperial crown upon his head. By his royal command, a magnificent feast was prepared in the banquet garden, and Niyatus, alongside Roman nobles and philosophers, took his seat at the King's table. Khosrow, arrayed in jewel-embroidered Roman robes, approached the board with a welcoming smile while Bandoy stood in attendance holding the sacred Barsam twigs. However, as the King of Kings recited the ancient Zoroastrian table grace—the silent Vaj—under his breath according to the rites of his ancestors, Niyatus grew incensed. Offended by this departure from Christian practice, the Roman commander threw down his bread and retreated from the table, exclaiming that merging secret Zoroastrian whispers with the reverence of the Cross was an insult by Caesar against Christ.
Witnessing such insolence at the royal table, Bandoy struck the back of his hand sharply across the face of the cross-worshipper. Khosrow was deeply grieved by this rash display, his countenance turning as pale as a yellow wild-rose. He chastised Gostahm, lamenting that Bandoy's folly had brought dishonor upon them before their foreign allies. Half-intoxicated and consumed by rage, Niyatus rode back to his camp, donned his battle armor, and readied his Roman cavalry to assault Khosrow's royal court. He dispatched a swift courier demanding that Bandoy be delivered into his hands immediately, threatening a full-scale riot if his request were denied.
Upon hearing this ultimatum, Khosrow flared with imperial pride, declaring that he would never abandon the ancient faith of his exalted ancestors—from Keyumars and Jamshid down to Kay Qobad—nor renounce his holy heritage to adopt the creed of Christ merely to appease Rome. Seeing the impending disaster, Queen Maryam, the sagacious Roman princess and wife of Khosrow, stepped forward. She offered to quell the violent uprising herself, taking Bandoy under her protection alongside ten horsemen and riding directly to Niyatus's camp.
With eloquent diplomacy and profound wisdom, Maryam confronted Niyatus. She reminded him of the solemn alliance forged by Caesar, the blood ties between their houses, and the emptiness of provoking a war over table customs. She reasoned that Iranian nobles never forsake their ancestral faith, and that Khosrow’s heart was already heavy with grief and vengeance for his slain father. Her words dissolved Niyatus's wrath and moved him to deep shame. Repentant, Niyatus returned swiftly to Khosrow's presence, offering apologies and acknowledging that a wise monarch must remain faithful to the religion of his forefathers. Thus, through Maryam's brilliant intervention, peace was restored between the empires.
