One other cistern at least is worth a visit. It is that which is approached from the outside of the Church of the Studium at its east end. It was originally the cistern of the monastery. It is now dry and filled with hay. It has a splendid vaulted roof and twenty-five columns with beautifully carved Corinthian capitals.

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.

THE PALACE OF THE PORPHYROGENITUS

The other palace is one about which the most extraordinary mistakes have been made. It is that which the Greeks call the house of Belisarius and the Turks Tekfûr Serai. It is an oblong building of three stories, facing north and south, and placed between the two walls which descend from the Xylokerkon Gate (Kerko-Porta), at which the Theodosian walls end, towards the Golden Horn. Gyllius believed this to be the famous palace of the Hebdomon, and nearly all the antiquaries have followed him. Professor Bury, among historians, had shown the impossibility of this identification; but it has remained for Professor van Millingen conclusively to show it to be the palace of the Porphyrogenitus. It was here that Andronicus III. resided in 1326 when Andronicus II. was at Blachernae. It was here that John Cantacuzene was in 1347 when he negotiated with the Empress. Architectural authorities differ as to its date. Some have placed it as early as Theodosius II., but it much more probably belongs to the tenth century and to the work of Constantine Porphyrogenitus. It is clearly later than the sixth century work of the palace of Hormisdas, being much more elaborate both in design and in decoration. The evidence for the identification is thus given by Professor van Millingen.[72]

"The evidence for the proper Byzantine name of Tekfûr Serai, occurs in the passage in which Critobolus describes the positions occupied by the various divisions of the Turkish army during the siege of 1453. According to that authority, the Turkish left wing extended from the Xylo-Porta (beside the Golden Horn) to the Palace of the Porphyrogenitus, which was situated upon a slope, and thence to the Gate of Charisius (Edirnè Kapoussi). The site thus assigned to the Palace of the Porphyrogenitus corresponds exactly to that of Tekfûr Serai, which stands on the steep ascent leading from Egri Kapou to the Gate of Adrianople."

Of the other palaces practically no remains exist. A few stones of Blachernae may be built into houses or walls on its site. Two lions from the Boukoleon, of which Anna Comnena speaks, stand in the gardens of the old Seraglio not far from Chinili Kiosk.[73] I know nothing else which belongs to any house of the Christian Emperors.

All these treasures of antiquity are still exposed to the sky; but those preserved in the Museum make it one of the finest in the world. The Turks have awoke to the fact that the lands most fruitful in archæological remains are now in their hands, and Hamdy Bey, the director of the imperial museum, has with indefatigable industry and admirable judgment made a magnificent collection of antiquities in the two buildings under his charge.
