Thus, also, the site of the Church of St. Lazarus can be approximately determined. From the order in which the churches visited by the Deacon Zosimus[931] between St. Sophia and St. George Mangana are mentioned, it is clear that the Church of St. Lazarus lay to the south of the Church of St. Saviour, and consequently somewhere between Indjili Kiosk and the Seraglio Lighthouse. The identification is important; for near the Church of St. Lazarus was found the tier of seats, known as the Topi, which marked the southern extremity of the walls of old Byzantium on the side of the Sea of Marmora.[932] Thus, also, the eastern limit of the grounds of the palace erected by Constantine the Great is determined. “The Triclinia erected by Constantine the Great,” says Codinus,[933] “reached to that point,” _i.e._ the Topi. Furthermore, the Tzycanisterion, or polo-ground, attached to the Great Palace, extended, we are told, as far as the neighbourhood of the Church of St. Lazarus and the Topi.[934] Dr. Paspates is therefore mistaken in making the palace grounds reach to within a short distance of the Seraglio Point. Near the Topi likewise stood the Thermæ Arcadianæ,[935] constructed by the Emperor Arcadius, and one of the finest ornaments of the capital. There, also, was a church dedicated to the Archangel Michael, ἐν Ἀρκαδιαναῖς.[936] In this neighbourhood, moreover, must have stood the Atrium of Justinian the Great,[937] a favourite public resort towards sunset, when the eastern side of the city was in shade, to admire the magnificent display of colour then reflected on the Sea of Marmora and the Asiatic coast and mountains. It was built of white marble and adorned with statuary, among which the statue of the Empress Theodora, upon a pillar of porphyry, was specially remarkable.[938] Still further south of the Church of St. Saviour rose one of the most venerated shrines in Constantinople, the Church of the Theotokos Hodegetria (τῶν Ὁδηγῶν) founded by the Empress Pulcheria, and reconstructed by Michael III.[939] It boasted of a Holy Well famed for marvellous cures,[940] and of an Icon of the Virgin, attributed to St. Luke, which was regarded as the palladium of the city and the leader (Ὁδηγητρία) of the hosts of the Empire to victory. Generals on leaving the city to engage in war paid their devotions at this shrine, and the sacred picture had the first place of honour in a triumphal procession, taking precedence of the emperor himself.[941] In view of the siege of the city by Branas, in the reign of Isaac Angelus, the Icon was carried round the fortifications;[942] while in 1453 it was placed in the Church of the Chora, not far from the Gate of Charisius, to support the defence. There, upon the capture of the city, it was found by the Turks, and cut to pieces.[943]
