In favour of the accuracy of Ducas, it must be admitted that his statements concerning the Horaia Pylè, in other passages of his work, convey the impression that under that name he refers to the entrance nearest the head of the promontory, the Gate of Eugenius (Yali Kiosk Kapoussi). Speaking of the arrangements made for the defence of the sea-board of the city, he describes them as extending, in the first place, from the Xylinè Porta, at the western extremity of the Harbour Walls, to the Horaia Pylè; and then from the Horaia Pylè to the Golden Gate, near the western extremity of the walls along the Sea of Marmora.[798] Again, when he describes the blockade of the shore of the city outside the chain by the Sultan’s fleet, he represents the blockade as commencing at the Horaia Pylè and proceeding thence past the point of the Acropolis, the Church of St. Demetrius, the Gate of the Hodegetria, the Great Palace, and the harbour (Kontoscalion), as far as Vlanga.[799] Now, the gate which would naturally form the pivot, so to speak, of these operations was the Gate of Eugenius. There the two shores of the city divide; and that was the farthest point to which the Turkish fleet outside the chain could advance into the Golden Horn. It would be strange if Ducas ascribed the strategical importance of the Gate of Eugenius to another gate. And yet, it must be also admitted that Ducas can be inaccurate. He is inaccurate, for example, in the matter of the gate before which the Sultan’s tent was pitched during the siege,[800] and at which the Emperor Constantine fell,[801] for he associates these incidents with the Gate of Charisius, instead of with the Gate of St. Romanus; he is inaccurate, as we have seen, in his account of the entry of the Turks through the Kerko Porta;[802] and he is inaccurate, again, in saying that the ships which the Sultan carried across the hills from the Bosporus to the Golden Horn were launched into the harbour at a point opposite the Cosmidion (Eyoub),[803] instead of at Cassim Pasha. Under these circumstances it is impossible to maintain his accuracy as to the connection of the chain with Horaia Pylè at all hazards, and in the face of all difficulties. His credit will depend upon the value attached to the evidence we have, that the Horaia Pylè was another name for the Gate of the Neorion during the last days of Byzantine Constantinople.
