The Patriarch Constantius, our sole informant on the subject, refers to this discovery twice; first, in his work on _Ancient and Modern Constantinople_ (Κωνσταντινιὰς Παλαιὰ τε καὶ Νεωτέρα), published in 1844; secondly, in a letter, dated April 12, 1852, which is found in the collection of his minor works (Συγγραφαὶ αἱ Ἐλάσσωνες), and which was addressed to Mr. Scarlatus Byzantius, upon the publication of that gentleman’s work on the history and antiquities of the city. In that letter the patriarch corrects several mistakes made in his own work on the same subject, and gives additional information on other points. The earlier reference to the discovery is brief, and when viewed in the light of the later statements, altogether misleading. It occurs in the paragraph upon Koum Kapoussi, the ancient Gate of Kontoscalion (English translation, p. 21; Greek original, p. 30). After expressing the opinion that the Neorion of the Kontoscalion stood at that gate, and quoting the description which Pachymeres gives of the wall around the harbour, the reverend author adds: “A portion of this circular enclosure appeared in 1819, consisting of three layers of very large stones placed one upon the other” (Ἕν μέρος δὲ τούτου τοῦ κυκλικοῦ περιφράγματος τοῦ λιμένος ἀνεφάνη τῷ 1819 ἔτει, συνιστάμενον ἐκ τριῶν θέσεων παμμεγίστων ἀλλεπαλλήλων πετρῶν). There can be but one meaning to this language, namely, that the enclosure referred to stood beside the harbour at Koum Kapoussi. But the difficulty with this language has always been how to make it coincide with the facts in the case. For, as already intimated, the enclosure around the harbour at Koum Kapoussi is almost intact, and consists of the ordinary walls of the city at their usual elevation. There has never been room at that point for another enclosure such as the patriarch describes. But his later, and, fortunately, fuller statements (Συγγραφαὶ αἱ Ἐλάσσωνες, pp. 443, 444) make the matter clear, although, at the same time, they convict the patriarch of inaccuracy in his first statement, so far as the locality of the discovery is concerned. According to the patriarch’s letter, the locality in question was not at Koum Kapoussi, but between that gate and the gate Yeni Kapou of Vlanga, and nearer to the latter entrance than to the former. This fact is confirmed by the additional indication that the discovery was made in a Turkish quarter; for the only Turkish quarter near the shore between Kadriga Limani, on the east of Koum Kapoussi, and Daoud Pasha Kapoussi, on the west of Vlanga, is the quarter of Tulbenkdji Djamissi near Yeni Kapou. But to render all doubt as to the situation of the locality impossible, the route taken to reach it is minutely described; the patriarch and
