at the storming, nor would the punishment of the citizens have there ended, but for Diocletian's humane interpretation of an accident. The horse on which he sat stumbled as he entered the city with his troops, and he had the humanity to understand it as a command from heaven that he should stop the pillage of the city; and the citizens in gratitude erected near the spot a bronze statue of the horse to which they owed so much. This statue has long since been lost, but we cannot be mistaken in the place where it stood. The lofty column in the centre of the temple of Serapis, now well known by the name of Pompey's Pillar,* once held a statue on the top, and on the base it still bears the inscription of the grateful citizens, "To the most honoured emperor, the saviour of Alexandria, the unconquerable Diocletian." * See Volume X., page 317. This rebellion had lasted more than nine years, and the Egyptians seemed never in want of money for the purposes of the war. Diocletian was struck with their riches, and he ordered a careful search to be made through Egypt for all writings on alchemy, an art which the Egyptians studied together with magic and astrology. These books he ordered to be burnt, under a belief that they were the great sources of the riches by which his own power had been resisted. Want and misery no doubt caused this rebellion, but the rebellion certainly caused more want and misery. The navigation of the Nile was stopped, the canals were no longer kept cleared, the fields were badly tilled, trade and manufactures were ruined. Since the rebellions against the Persians, Egypt had never suffered so much. It had been sadly changed by the troubles of the last sixty years, during which it had been six times in arms against Rome; and when the rebellion was put down by Diocletian, it was no longer the same country that it had been under the Antonines. The framework of society had been shaken, the Greeks had lessened in numbers, and still more in weight. The fall of the Ptolemies, and the conquest by Rome, did not make so great a change. The bright days of Egypt as a Greek kingdom began with the building of Alexandria, and they ended with the rebellions against Gallienus, Aurelian and Diocletian. The native Egyptians, both Kopts and Arabs, now rise into more notice, as the Greek civilisation sinks around them. And soon the upper classes among the Kopts, to avoid the duty of maintaining a family of children in such troubled times, rush by thousands into monasteries and convents, and further lessen the population by their religious vows of celibacy. In the twelfth year of the reign, that in which Alexandria rebelled and the siege was begun, the Egyptian coinage for the most part ceased. Henceforth, though money was often coined in Alexandria as in every other great city of the empire, the inscriptions were usually in Latin, and the designs the same as those on the coins of Rome.
