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.
