Apollonius; I have paid these four gentlemen, and therefore I have paid you.” (C) ART. Unimportant. Alexandria had her special industries—_e.g._ glass, terra cotta, “Egyptian Queen” pottery, and woven stuffs, and her mint was famous; but for creative artists the Ptolemies looked over seas. Greek and Egyptian motives did not blend in Art as they did in Religion; attempts occur, but they are not notable and on the whole the city follows the general Hellenistic tendencies of the time. These tendencies led as we have seen away from the ideal and the abstract, and towards portraiture and the dainty and the picturesque. Men had lost for the time many illusions, both religious and political, and were trying to beautify their private lives, and the tombs of those whom they had loved. GLASS AND “EGYPTIAN QUEEN” POTTERY: Museum, Room 17. TERRA COTTAS: Museum, Room 18. PTOLEMAIC COINS: Museum, Room 3. BLEND OF GREEK AND EGYPTIAN MOTIVES: Museum Rooms 11 and 15; also Kom es Chogafa Catacombs, (p. 148). TOMB ORNAMENTS: Museum, Rooms 17-22. (D) PHILOSOPHY. Unimportant. The Ptolemies imported some second-rate disciples of Aristotle to give tone to the Mouseion, but took no interest in the subject, and were indeed averse to it, since it might lead to freedom of thought. It was not until their dynasty was extinct that the great school of Alexandrian Philosophy arose. (See p. 60, under heading “The Spiritual City.”) (E) SCIENCE. The Ptolemies were more successful over Science than over Literature. They preferred it, for it could not criticise their divine right. Its endowment was the greatest achievement of the dynasty and makes Alexandria famous until the end of time. Science had been studied in Ancient Greece, but sporadically: there had been no co-ordination, no laboratories, and though important truths might be discovered or surmised, they were in danger of oblivion because they could not be popularised. The foundation of the Mouseion changed all this. Working under royal patronage and with every facility, science leapt to new heights, and gave valuable gifts to mankind. The third century B.C. is (from this point of view) the greatest period that civilisation has ever known—greater even than the nineteenth century A.D. It did not bring happiness or wisdom: science never does. But it explored the physical universe and harnessed many powers for our use. Mathematics, Geography, Astronomy, Medicine, all grew to maturity in the little space of the land between the present Rue Rosette and the sea, and if we had any sense of the fitting, some memorial to them would arise on the spot to-day.
