To have carried forward the many important works which the great leader instituted, and which were advanced with a precision and rapidity remarkable for that or any other time, considering their size and importance, the skill and services of many architects were brought naturally into requisition. As a result we have the record of an unusually large number of such artists, and in respect to a few some little specific data relating to their lives. The architects, however, of many of the most important works are unknown. If we approach Athens, like the Attic mariner of old, through the Piræus, one of its sea gates, we are attracted at once to the beautiful architectural display which this seaport town, some five or six miles distant from the Grecian metropolis, presents. The entrance to the harbor was ornamented with two lions, and the harbor-basin was fringed with magnificent colonnades and porticos, which disguised the warehouses and bazaars. Within the town were numerous temples, two theatres and other buildings of artistic effect and merit. The road to Athens lay between massive fortified walls having a width of fifteen feet at the top, and built to a height of sixty feet. They were known as the “Long Walls,” and they enclosed a space about the Piræus, said by Thucydides to have been not less than one hundred and twenty-four stadia in circumference, or about fifteen miles. It is only just to state that the walls which led from Athens to Piræus, as well as those which connected it with the other sea gates of Munychia and Phalerus, were originally planned and partly executed under Themistocles and Cimon. Themistocles intended to construct these walls to a height of one hundred and twenty feet; but Pericles deemed this entirely unnecessary, and cut the height in two, as we have seen. He also added a third wall between that running to the north of the Piræan fortifications and that reaching to the Phalerum. Socrates speaks of having heard Pericles mention this wall to the people. The architects for much of this massive mural work were Hippodamus and Callicrates, and because Pericles did not hurry them to the same extent that he hurried others engaged in perhaps less important, if more decorative, undertakings, Cratinus, the satirist, ridiculed the slowness of the work, while aiming a sly shaft of irony at Pericles’s oratorical gifts: “Stones upon stones the orator has pil’d With swelling words, but words will build no walls.”
