intervals in the history of the city. Many mistakes in the topography of Constantinople are due to this false method of identification. As a matter of fact, the monastery of Manuel near the cistern of Aspar was not the only House of that name in the capital of the East. Another monastery of Manuel stood beside the Golden Horn, in the Genoese quarter, between the gate of the Neorion (Bagtché Kapoussi) and the gate of Eugenius (Yali Kiosk Kapoussi). It had a pier, known as the pier of the venerable monastery of Manuel, [Greek: skala tês sebasmias monês tou Manouêl].[438] Paspates is consequently wrong in associating that pier with Kefelé Mesjedi.[439] [Illustration: PLATE LXXIV. S. THEODORE. THE OUTER NARTHEX, LOOKING NORTH.] [Illustration: S. THEODORE. CAPITAL TO THE NORTH OF THE DOOR LEADING FROM THE OUTER TO THE INNER NARTHEX. _To face page 254._] Mordtmann[440] accepts the identification of Kefelé Mesjedi with the monastery of Manuel as correct, but he identifies it also with the church and monastery which Gerlach found in this neighbourhood, and describes under the name of Aetius ([Greek: tou Aetiou]).[441] When visited by Gerlach in 1573, the church had been converted into a mosque, and was a beautiful building in excellent preservation. If all that remains of it is the bare structure of Kefelé Mesjedi, the city has to mourn a great loss.[442] (Plate LXXVII.) Manuel, the founder of the monastery, was the uncle of the Empress Theodora, wife of the Emperor Theophilus, and proved a loyal and devoted servant of the imperial family. Twice at the peril of his own life he saved the emperor from capture, if not from death, during the wars with the Saracens. Nevertheless, being accused of treason he fled to the court of Baghdad and took service under the Caliph Mutasim, until assured that Constantinople would welcome him back.
