Among various resident colonists who may have occupied distinct sections of the city, like a mediæval Ghetto or a modern Italian quarter, the worship of home divinities was kept alive. It is known, for example, that the Egyptian resident merchants, perhaps as early as the end of the fifth century, had received a special license to erect an Isis sanctuary and the Cyprians instituted a similar cult of Adonis and Aphrodite. Remains of the old gateway in the northern circuitwall, just where the north Long Wall joined on, are still extant. Within a century, the traces of the Long Walls themselves have been disappearing. Enough is left, however, to mark their course at various points, and the remains are particularly plain of the “South” Long Wall, where it nears the Munychia acropolis. Ascending Munychia, we may imagine the Long Walls still reaching up to Athens. We may picture them either in time of war, with defenders within and foes without, or in time of peace, with the stream of pedestrians bent upon pleasure or business. Outside the North Wall was one of the places of execution. Plato illustrates the contest between the brute in man and his higher reason by the story of a certain Leontius who one day was walking up from Piræus and saw some dead bodies fallen prostrate by the side of the executioner. He loathes the sight but is fain to look. Vulgar curiosity gains the mastery; he runs up to the dead bodies and, holding his eyelids wide open, exclaims: “There wretches! Take your fill of the fine spectacle!” Turning from the course of the Long Walls, the eye surveys the whole panorama of the harbours and the city. Just within the old wall, on the west slope of the Munychia hill, is the old Theatre in a ruined condition. But we can think of the harbour folk in days of peace enjoying on these same rising seats the plays of a Menander or Euripides or see convened there in the times of grim civil strife a hurried assembly of the patriotic party. Somewhere close by the north side of Zea was the famous arsenal which, though not built till near the end of the fourth century, has entirely disappeared. Luckily, however, in 1882 there was discovered near the Zea harbour a slab of Hymettus marble containing the directions given to the contractors for its construction. It was built to contain the rigging, tackle, sails, cables for undergirding the ships, etc., while the masts, spars, oars, rudders, and other wooden gear seem to have been kept in the ship-sheds themselves alongside of the ships. This arsenal of Philo replaced an older and less elaborate one. It was a large building, four hundred by five hundred feet within, and provided for a roomy arcade where the populace, screened from the burning heat without, could promenade and gaze at the suggestive evidences of their sea power.
