These arguments are, however, open to criticism. So far as the statement of Leonard of Scio is concerned, it should be noted that he does not speak of the Turris Phani absolutely. Had he done so, the presumption would certainly be in favour of the view which understands him to refer to the district of the Phanar, half-way up the Golden Horn.[854] But his complete statement on the subject is that the Turris Phani of which he was speaking stood, with the Imperial Gate beside it, “ante sinum,” at the entrance of the bay of the Golden Horn, thus making it manifest that he had in mind another beacon-tower than the one in the district commonly known as the Phanar. That the shore of the Golden Horn was lighted at more than one point during the night, and especially at the entrance of the harbour, is only what might be expected. Nor is there in the assertion of Ducas, that the Venetians and Greeks united their forces to defend the fortifications from the Imperial Gate to the Kynegon, anything to determine the distance between the two points. They might be very near, or they might be as far apart as the extremities of the Harbour Walls; for there is no reason to think that the Venetians defended only the small portion of the walls between Balat Kapoussi and the three archways to the west of that gate. The remaining arguments under consideration have more force, but are by no means decisive. The appropriateness of the epithet “Imperial” to an entrance in the situation of Balat Kapoussi affords, certainly, a presumption in favour of the view that the entrance was so named, although it cannot, alone, prove that such was the fact. The name Balat Kapoussi appears only after the Turkish Conquest, and may or may not be borrowed from the Byzantine designation of the gate. The strongest argument on this side of the question is, undoubtedly, that drawn from the presence of the Church of St. John the Baptist on the shore to the north-east of Balat Kapoussi,[855] the possible representative of the ancient church of that dedication “on the shore outside the Basilikè Pylè.”[856] But, in any case, these arguments do not refute the proof adduced for the existence of a Basilikè Pylè near the Seraglio Point. They leave that fact undisturbed; and can only claim to give countenance to the idea that another Basilikè Pylè stood at Balat Kapoussi. Two questions, accordingly, are involved in the problem before us. Which of the gates near the Seraglio Point was styled the Basilikè Pylè? Was that gate the only Imperial Gate in the line of the Harbour Walls, or do some statements of Byzantine historians on the subject imply the existence of a second Basilikè Pylè?
