In following the course of these walls to note the arrangements of the city, and to recall historical associations, only a very brief mention of what is most prominent and memorable is here possible. Beginning at the head of the promontory, we have first the eastern portion of the Seraglio Grounds, presenting to view the crags upon which stood the Acropolis of old Byzantium. To become the master of that hilltop, with its wonderful outlook and great strategic value was the ambition of Xenophon and “The Ten Thousand” on their famous retreat from Persia, of Philip of Macedon, of Severus Septimius, of Constantine the Great, not to mention other aspirants. After the foundation of Constantinople, until Turkish days, the site of the Acropolis formed an ordinary part of the city, the most conspicuous edifice on that position being the Church of S. Irene. There also was the hospital of Sampson, as well as that of Eubulus. Among the buildings on the level tract below the Acropolis were two theatres, inherited from Byzantium, one of which has left its stamp in the hollow ground now occupied by the vegetable gardens to the rear of Deïrmen Kapoussi. Scattered over the adjoining territory was a crowd of churches in which saints encamped to guard this exposed point of the city; a host led by S. Barbara, patroness of arms, S. George, the Slayer of the Dragon, S. Mary Hodegetria, with her icon ascribed to S. Luke, and regarded as a palladium. The Mangana or Arsenal, stored with military engines for the defence of the walls, also stood in this vicinity. The vaulted substructures near the ruins of Indjili Kiosk belonged to the Palace of the Mangana, to which the imperial household resorted to enjoy the cool breezes that winged their way down the Bosporus from the north. Here also was a public park, the Philopation, and an atrium built by Justinian the Great, crowded on summer afternoons, when this side of the city is in shade, by people who loved to look out upon the sparkling water, and the hills of the opposite Asiatic shore, resplendent in the mellow light of the setting sun. The fine building that formed the Thermæ of Arcadia was in this neighbourhood, and a portion of the polo grounds, Tzycanisterion, attached to the palace of the Byzantine emperors.
