In view of its proximity to the landward walls, the Chora acquired great importance during the fatal siege of 1453. For the inhabitants of the beleagured capital placed their hope for deliverance more upon the saints they worshipped than upon their own prowess; the spiritual host enshrined in their churches was deemed mightier than the warriors who manned the towers of the fortifications. The sanctuaries beside the walls constituted the strongest bulwarks from which the 'God protected city' was to be defended, not with earthly, but with heavenly weapons. The eikon of the Theotokos Hodegetria was, therefore, taken to the Chora to guard the post of danger. It represented the Theotokos as the Leader of God's people in war, and around it gathered memories of wonderful deliverances and glorious triumphs, making it seem the banner of wingless victory. When the Saracens besieged the city the eikon was carried round the fortifications, and the enemy had fled. It led Zimisces in his victorious campaign against the Russians; it was borne round the fortifications when Branas assailed the capital in the reign of Isaac Angelus, and the foe disappeared; and when Constantinople was recovered from the Latins, Michael Palaeologus only expressed the general sentiment in placing the eikon on a triumphal car, and causing it to enter the city before him, while he humbly followed on foot as far as the Studion. But the glory of the days of old had departed, and no sooner did the troops of Sultan Mehemed force the Gate of Charisius (Edirné Kapoussi) than they made for the Chora, and cut the image to pieces. The church of S. Saviour in the Chora was the first Christian sanctuary to fall into the hands of the Moslem masters of Constantinople. The building was converted into a mosque by Ali Atik Pasha, Grand Vizier, between 1495 and 1511, in the reign of Bajazet II. Gyllius visited the church in 1580, and expatiates upon the beauty of its marble revetment, but makes no reference to its mosaics and frescoes.[536] This, some authorities think, proves that these decorations were then concealed from view, because objectionable in a place consecrated to Moslem worship. But the silence of the traveller may be due to the brevity of his description of the church. There is evidence that the building has suffered much since the Turkish conquest from earthquake and from fire, but the precise dates of these disasters cannot be accurately determined. The mosque disappeared from general view until 1860, when it was discovered by a Greek architect, the late Pelopidas D. Kouppas. Mr. Carlton Cumberbatch, then the British Consul at Constantinople, was informed of the fact and spread the news of the fortunate find.
