As one wanders through the streets many remains of Byzantine building, even in the parts that have been almost entirely rebuilt by the Turks, are to be seen. There is one especially notable in the long street that leads to Top Kapoussi (the gate of S. Romanus). The great Imperial Palace about which antiquaries have waged so fierce a fight, has left not one stone upon another; so I will not rashly utter my own opinion of the evidence as to its site. Remains of only two of the Byzantine palaces are now to be found. The first is the surely falling wall which arrests attention as the traveller by the sea of Marmora follows the course of the sea walls before rounding the point. It is close to the Church of S. Sergius and S. Bacchus, and the identification of it with the house of Hormisdas purchased by Justinian, and afterwards enlarged by him, may be regarded as certain. It is the "palace of the King, which was formerly called by the name of Hormisdas," of which Procopius says that it was once Justinian's private house, "and when he became Emperor he made it look worthy of a palace by the magnificence of its buildings, and joined it to the other imperial apartments."[71] It was here that Justinian was living when he had determined to fly, crossing the sea to Chalcedon, and that Theodora made her heroic and historic speech (see p. 33). Now but a single wall remains. Some capitals are strewn in the sea near it. A water gate, with an inscription evidently referring to the Nika sedition, was still standing a few years ago. Canon Curtis told me of its interest in 1896: I searched for it, but it had absolutely disappeared. The solitary wall will probably soon follow it. [Illustration: THE PALACE OF THE PORPHYROGENITUS]
