reverse the laws of Nero, especially those relating to treason. While in Egypt, he visited the Temple of Serapis where he reportedly experienced a vision. Later, he was confronted by two labourers, who were convinced that he possessed a divine power that could work miracles. The praefectus Aegypti was Tiberius Julius Alexander, who had been governor since Nero's reign. He proclaimed Vespasian emperor at Alexandria on 1 July 69 AD. The prefect was himself of Hellenized Jewish descent and related to Philo of Alexandria. The importance of the Egyptian grain harvest () to Rome helped Vespasian assert control over the whole empire. Vespasian was the first emperor (and pharaoh) since Augustus to appear in Egypt. At the hippodrome of Alexandria he was hailed as pharaoh; recalling the welcome of Alexander the Great at the Oracle of Zeus-Ammon of the Siwa Oasis, Vespasian was proclaimed the son of the creator-deity Amun (Zeus-Ammon), in the style of the ancient pharaohs, and an incarnation of Serapis in the manner of the Ptolemies. As Pharaonic precedent demanded, Vespasian demonstrated his divine election by the traditional methods of spitting on and trampling a blind and crippled man, thereby miraculously healing him. (This Egyptian tradition of healing is related to the healing the man blind from birth, one of the miracles of Jesus of Nazareth.) Emperor (69–79) Aftermath of the civil war Vespasian was declared emperor by the Senate while he was in Egypt on 21 December 69; the Egyptians had declared him emperor in the summer. In the short-term, administration of the empire was given to Mucianus who was aided by Vespasian's son, Domitian. Mucianus started off Vespasian's rule with tax reform that was to restore the empire's finances. After Vespasian arrived in Rome in mid-70, Mucianus continued to press Vespasian to collect as many taxes as possible. Vespasian and Mucianus renewed old taxes and instituted new ones, increased the tribute of the provinces, and kept a watchful eye upon the treasury officials. The Latin proverb Pecunia non olet ("Money does not stink") may have been created when he had introduced a urine tax on public toilets. Before Vespasian, this tax was imposed by Emperor Nero under the name of vectigal urinae in the 1st century AD. However, the tax was removed after a while; it was re-enacted by Vespasian around 70 AD in order to fill the treasury. Vespasian's policy was not well received
