Before Vespasian returned to Rome to take up the reins of imperial government, he reportedly had a vision in the Serapeum of Alexandria and, as the New Serapis, healed two men. These wonders came to define Vespasian's time in Egypt and yet, for modern readers, their prominence in the story of the emperor's rise to power creates an apparent inconsistency. The same man who on his deathbed joked about his impending divinization also apparently played the part of a god at the beginning of his reign. Such contradictions are to be expected in the colourful accounts of emperors' lives, but this particular one invites further investigation because of its significance to the historical development of the conception of the emperor's divinity. Through detailed consideration of the prospects for reception of these wonders both during and after the Flavian dynasty, this article seeks to demonstrate the predominance of Domitianic influence on the story of Vespasian's wonders. Domitian's reign saw a new emphasis on the living emperor's divinity, which diminished again under Trajan. Nevertheless, wonders were a means through which the charisma of the emperor was manifested in Flavian Rome and later.
