4. In Libya Pentapolis is Cyrene, a city of great antiquity, but now deserted, founded by Battus the Spartan, and Ptolemais, and Arsinoë, known also as Teuchira, and Darnis, and Berenice, called also Hesperides. 5. And in the dry Libya, besides a few other insignificant towns, there are Parætonium, Chærecla, and Neapolis. 6. Egypt proper, which ever since it has been united to the Roman empire has been under the government of a prefect, besides some other towns of smaller importance, is distinguished by Athribis, and Oxyrynchus, and Thmuis, and Memphis. 7. But the greatest of all the cities is Alexandria, ennobled by many circumstances, and especially by the grandeur of its great founder, and the skill of its architect Dinocrates, who, when he was laying the foundation of its extensive and beautiful walls, for want of mortar, which could not be procured at the moment, is said to have marked out its outline with flour; an incident which foreshowed that the city should hereafter abound in supplies of provisions. 8. At Inibis the air is wholesome, the sky pure and undisturbed; and, as the experience of a long series of ages proves, there is scarcely ever a day on which the inhabitants of this city do not see the sun. 9. The shore is shifty and dangerous; and as in former times it exposed sailors to many dangers, Cleopatra erected a lofty tower in the harbour, which was named Pharos, from the spot on which it was built, and which afforded light to vessels by night when coming from the Levant or the Libyan sea along the plain and level coast, without any signs of mountains or towns or eminences to direct them, they were previously often wrecked by striking into the soft and adhesive sand. 10. The same queen, for a well-known and necessary reason, made a causeway seven furlongs in extent, admirable for its size and for the almost incredible rapidity with which it was made. The island of Pharos, where Homer in sublime language relates that Proteus used to amuse himself with his herds of seals, is almost a thousand yards from the shore on which the city stands, and was liable to pay tribute to the Rhodians. 11. And when on one occasion the farmers of this revenue came to make exorbitant demands, she, being a wily woman, on a pretext of it being the season of solemn holidays, led them into the suburbs, and ordered the work to be carried on without ceasing. And so seven furlongs were completed in seven days, being raised with the soil of the adjacent shore. Then the queen, driving over it in her chariot, said that the Rhodians were making a blunder in demanding port dues for what was not an island but part of the mainland.
