hands; and many columns, too, from tombs, and sculptured stones were put in with the rest. For the bounds of the city were extended at every point of the circumference; and so they laid hands on everything without exception in their haste. Themistocles also persuaded them to finish the walls of Piraeus, which had been begun before, in his year of office as archon; being influenced alike by the fineness of a locality that has three natural harbours, and by the great start which the Athenians would gain in the acquisition of power by becoming a naval people. For he first ventured to tell them to stick to the sea and forthwith began to lay the foundations of the empire. It was by his advice, too, that they built the walls of that thickness which can still be discerned round Piraeus, the stones being brought up by two wagons meeting each other. Between the walls thus formed there was neither rubble nor mortar, but great stones hewn square and fitted together, cramped to each other on the outside with iron and lead. About half the height that he intended was finished. His idea was by their size and thickness to keep off the attacks of an enemy; he thought that they might be adequately defended by a small garrison of invalids, and the rest be freed for service in the fleet. For the fleet claimed most of his attention. He saw, as I think, that the approach by sea was easier for the king’s army than that by land: he also thought Piraeus more valuable than the upper city; indeed, he was always advising the Athenians, if a day should come when they were hard pressed by land, to go down into Piraeus, and defy the world with their fleet. Thus, therefore, the Athenians completed their wall, and commenced their other buildings immediately after the retreat of the Mede.
Meanwhile Pausanias, son of Cleombrotus, was sent out from Lacedaemon as commander-in-chief of the Hellenes, with twenty ships from Peloponnese. With him sailed the Athenians with thirty ships, and a number of the other allies. They made an expedition against Cyprus and subdued most of the island, and afterwards against Byzantium, which was in the hands of the Medes, and compelled it to surrender.
