Kahrieh Jami, popularly known as the mosaic mosque, is in every way one of the most interesting monuments of Constantinople. Like Imrahor Jamisi it was originally the church of a monastery, and its history goes back as far. Like the Studion, also, it suffered from the quarrels of iconoclasm, it gave hospitality at a historic moment—namely during the last siege—to the miraculous icon of the Shower of the Way, and it fell into Turkish hands during the reign of Baïezid II. Kahrieh Jami means the Mosque of Woe, from the scenes that were enacted there when the Turks stormed the walls. The church seems always to have had a particular connection with Syria. The abbot Theodore, an uncle of Justinian’s empress, came to it from Antioch in 530. Again in the ninth century, when the iconoclasts were finally beaten, the celebrated Syrian monk Michael was made abbot, while pilgrims from Syria always made the monastery their headquarters. The church we know was not the church built outside the walls of Constantine as early, it may be, as the fourth century. The original church was successively rebuilt in the sixth century—by Justinian—in the seventh, in the ninth, and in the eleventh or at the beginning of the twelfth. To this latter restoration by Mary Ducas, a princess with Bulgarian blood in her veins, the church owes its present lines and perhaps a part of its interior decoration.
