Upon reading Shapur’s reply, Baranush's heart was filled with relief and joy. He commanded a delegation of a hundred Roman nobles to assemble, bearing sixty loads of silver coins, precious jewels, and magnificent royal garments, along with thirty thousand gold dinars as an offering. The Roman dignitaries approached Shapur barefoot and bareheaded, scattering gold before his feet. Shapur received them with royal grace, bestowing honors according to their rank. He reminded Baranush of the vast destruction wrought upon Iranian lands by Roman invasions—how thriving cities had been turned into wilderness and lairs for beasts—and demanded full restitution.
Shapur stipulated that Rome must pay a heavy tribute three times a year, consisting of millions in gold, and permanently cede the strategic city of Nisibis to Iran. Baranush agreed to all terms, and a solemn treaty was ratified, ensuring peace provided Rome honored the pact. Shapur then offered prayers of praise to Almighty God and traveled in triumph toward Istakhr of Fars.
However, when news reached Nisibis, its Christian inhabitants rebelled, refusing to accept Sasanian governance or Zoroastrian customs. Indignant, Shapur dispatched a formidable army. After a week of fierce fighting and siege, the defenders were overwhelmed; their leaders were slain or bound in chains, and the city surrendered. Shapur magnanimously granted them pardon and recalled his legions.
Thereafter, Shapur honored the brave Roman slave girl who had engineered his escape, naming her Dilfruz Farrokh-Pesh ("Heart-Delighter of Auspicious Countenance") and elevating her among his court, while also bestowing rich rewards upon the generous gardener who had aided him. Meanwhile, the captive Roman Caesar died in his dungeon after a period of misery and imprisonment. Shapur treated the dead emperor with solemn dignity, placing his body in a casket with a musk-scented crown and sending him back to Rome, reflecting deeply upon the fleeting nature of earthly glory and human fate.
