According to Zosimus, Vaballathus died on the way to Rome, but this theory has been neither confirmed nor disproved. Other sources have implied that after shipping the defeated Zenobia and Vaballathus to Rome, Aurelian allowed both of the rebels to live, but only after they had been marched through the streets of the imperial city in accordance with Roman traditions of celebrating military victories with a triumphal procession. This would have been humiliating, but better than death. This theory is supported by Aurelian's similar treatment of the Tetrici, Tetricus I and Tetricus II of the Gallic Empire, long-time enemies of Rome whom the emperor allowed to retire following their defeat at the Battle of Châlons in 274.
