Laodicea was famous for tapestries, Hierapolis for its iron wares, Cybara for its dyes, Sardis for its wines, Smyrna for its beautiful monuments, Delos for its slave-trade, Cyrene for its horses, Paphos for its temple of Venus, in which were a hundred altars. Seleucia, on the Tigris, had a population of four hundred thousand. Caesarea in Palestine, founded by Herod the Great, and the principal seat of government to the Roman prefects, had a harbor equal in size to the renowned Piraeus, and was secured against the southwest winds by a mole of such massive construction that the blocks of stone, sunk under the water, were fifty feet in length, eighteen in width, and nine in thickness. The city itself was constructed of polished stone, with an agora, a theatre, a circus, a praetorium, and a temple to Caesar. Tyre, which had resisted for seven months the armies of Alexander, remained to the fall of the empire a great emporium of trade; it monopolized the manufacture of imperial purple. Sidon was equally celebrated for its glass and embroidered robes. The Sidonians cast glass mirrors, and imitated precious stones. But the glory of both Tyre and Sidon was in ships, which visited all the coasts of the Mediterranean, and even penetrated to Britain and India. But greater than Tyre or Antioch, or any eastern city, was Alexandria, the capital of Egypt. Egypt even in its decline was still a great monarchy; and when the sceptre of three hundred kings passed from Cleopatra the last of the Ptolemies, to Augustus Caesar the conqueror at Actium, the military force of Egypt is said to have amounted to seven hundred thousand men. The annual revenues of this State under the Ptolemies amounted to about seventeen million dollars in gold and silver, besides the produce of the earth. A single feast cost Philadelphus more than half a million of pounds sterling, and he had accumulated treasures to the amount of seven hundred and forty thousand talents, or about eight hundred and sixty million dollars. What European monarch ever possessed such a sum? The kings of Egypt, even when tributary to Rome, were richer in gold and silver than was Louis XIV. in the proudest hour of his life.
