Here, accordingly, we have traces of all that constitutes a harbour: its mole, its entrance, its basin and enclosure, indicating where the Neorion at the Heptascalon, which the language of Cantacuzene and Nicephorus Gregoras obliges us to distinguish from the Kontoscalion, was probably situated. At this point, it seems reasonable to think, stood also the Harbour of Kaisarius, if we may judge from the circumstance that a fire which originated at that harbour extended up the valley from Vlanga to Ak Serai.[1177] In the opinion of the Patriarch Constantius,[1178] indeed, the harbour discovered in 1819 was the Kontoscalion. The statement of Pachymeres[1179] and Bondelmontius,[1180] that the Kontoscalion was near Vlanga, cannot, perhaps, be held to lend much countenance to this supposition, for in view of the short distance between Vlanga and Koum Kapoussi, the Kontoscalion might be thus described, although situated in front of the latter. But what presents a most serious consideration in favour of the patriarch’s opinion is the fact that the wall which he examined answered exactly to the description of the wall with which Michael Palæologus enclosed the Kontoscalion. That emperor, according to Pachymeres,[1181] surrounded the Kontoscalion with very large stones; and closed the entrance in the stones with iron gates (Ὥστε γυρῶσαι μὲν μεγίσταις πέτραις τὸν κύκλῳ τόπον, ... πύλας δ᾽ ἐπιθεῖναι ἀραρυίας ἐκ σιδήρου τῇ ἐν ταῖς πέτραις εἰσίθμη ἔξωθεν). No language could describe better the enclosure of large blocks discovered in 1819; while the expression “the entrance in the stones” applies admirably to the gap in the mole which protected the harbour. Nothing of the kind is found at the harbour before Koum Kapoussi, which lay within a mole and a great curve of the ordinary city walls. This, it must be admitted, is an exceedingly strong argument in support of the patriarch’s contention. On the other hand, we have seen how strong also are the arguments in favour of the view that the Kontoscalion stood at Koum Kapoussi.[1182] Perhaps the solution of the difficulty is found in the supposition that while the name Kontoscalion strictly belonged to the harbour at Koum Kapoussi, it was sometimes applied also to other harbours in the vicinity, because the name of the most important member of the group.
