Of the native magistrates in the cities, the first is the expounder of the law, who is dressed in scarlet; he receives the customary honours of the country, and has the care of providing what is necessary for the city. The second is the writer of records, the third is the chief judge. The fourth is the commander of the night guard. These magistrates existed in the time of the kings, but in consequence of the bad administration of affairs by the latter, the prosperity of the city was ruined by [CAS. 797] licentiousness. Polybius expresses his indignation at the state of things when he was there: he describes the inhabitants of the city to be composed of three classes; the (first) Egyptians and natives, acute but indifferent citizens, and meddling with civil affairs. The second, the mercenaries, a numerous and undisciplined body; for it was an ancient custom to maintain foreign soldiers, who, from the worthlessness of their sovereigns, knew better how to govern than to obey. The third were the Alexandrines, who, for the same reason, were not orderly citizens;[817] but still they were better than the mercenaries, for although they were a mixed race, yet being of Greek origin, they retained the customs common to the Greeks. But this class was extinct nearly about the time of Euergetes Physcon, in whose reign Polybius came to Alexandreia. For Physcon, being distressed by factions, frequently exposed the multitude to the attacks of the soldiery, and thus destroyed them. By such a state of things in the city the words of the poet (says Polybius) were verified: “The way to Egypt is long and vexatious.”[818] 13. Such then, if not worse, was the condition of the city under the last kings. The Romans, as far as they were able, corrected, as I have said, many abuses, and established an orderly government, by appointing vice-governors, nomarchs, and ethnarchs, whose business it was to superintend affairs of minor importance. The greatest advantage which the city possesses arises from its being the only place in all Egypt well situated by nature for communication with the sea by its excellent harbour, and with the land by the river, by means of which everything is easily transported and collected together into this city, which is the greatest mart in the habitable world.
