The reasons which favour the identification of the mosque Eski Imaret Mesjedi, which is situated on the heights above Aya Kapou (Gate of S. Theodosia), with the church of S. Saviour Pantepoptes, the All-Seeing ([Greek: pantepoptês]), are the following: first, the tradition to that effect,[347] which in the case of a building so conspicuous can scarcely be mistaken; secondly, the correspondence of its position to that of the Pantepoptes, on a hill commanding an extensive view of the Golden Horn;[348] and finally, the architectural features which mark it to be what the church of the Pantepoptes was, a building of the Comnenian period. The church of the Pantepoptes was founded or restored by Anna Dalassena,[349] the mother of Alexius I. Comnenus (1081-1118), one of the most remarkable women in Byzantine history, combining to a rare degree domestic virtues with great political ambition and administrative ability. For twenty years she was associated with her son in the government of the Empire, and was the power behind the throne which he owed largely to her energy and devotion. About the year 1100 she laid aside the cares of state, and without renouncing altogether her royal style retired to rest in the monastery she had built, until her death, five years later, at an advanced age.[350] There is nothing of special importance to record in the annals of the House. Its inmates were occasionally disturbed by the confinement among them of some dignitary who had offended the Government, or by the theological disputes that agitated the ecclesiastical circles of the capital.[351] But for the most part life at Pantepoptes was quiet and peaceful. Only once does the monastery stand out conspicuous before the eyes of the world. When the Venetian ships under Henrico Dandolo, with the army of the Fourth Crusade on board, lined the shore of the Golden Horn from Ispigas and the church of S. Saviour the Benefactor to Blachernae (_i.e._ from Jubali Kapoussi to Aivan Serai) on Easter Monday, 12th April 1204, the Emperor Alexius Murtzuphlus established his headquarters beside the Pantepoptes. There he pitched his vermilion tent, marshalled his best troops, and watched the operations of the enemy. And thence he fled when he saw the walls on the shore below him carried by storm, and Flemish knights mounted on horses, which had been landed from the hostile fleet, advancing to assault his position. So hurried was his flight that he left his tent standing, and under its shelter Count Baldwin of Flanders and Hainault slept away the fatigue of that day's victory.[352] During the Latin occupation the church passed into the hands of the Venetians, and was robbed of many of its relics for the benefit of churches in the West.[353] Upon the Turkish conquest it served for some time as an imaret or refectory for the students and teachers of the _medressé_,[354] then in course of construction beside the great mosque of Sultan Mehemed. Hence its Turkish name.
