The three Byzantine gates just named were situated in the quarter assigned to the Venetians in Constantinople by successive Imperial grants from the time of Alexius Comnenus to the close of the Empire. The Gate of the Drungarii marked the western extremity of the quarter;[748] the Gate of the Perama, its eastern extremity;[749] while the gate beside the Church of the Forerunner was between the two points. Where the Gate of the Perama stood admits of no doubt. All students of the topography of the city are agreed in the opinion that the entrance so named was at Balouk Bazaar Kapoussi. Consequently, the two other gates in the Venetian quarter lay to the west of Balouk Bazaar Kapoussi, in the portion of the fortifications between that entrance and the Gate of the Platea, all gates further west being out of the question. But as the only two gates in that portion of the walls are Zindan Kapoussi and Oun Kapan Kapoussi, they must represent, respectively, the Gate of the Forerunner and the Gate of the Drungarii. The Gate of the Drungarii (τῶν Δρουγγαρίων) derived its name from the term “Drungarius,” a title given to various officials in the Byzantine service;[750] as, for example, to the admiral of the fleet (μέγας δρουγγάριος τοῦ θεοσώστου στόλου), and to the head of the city police, the Drungarius Vigiliæ. (ὁ τῆς Βίγλας δρουγγάριος). In this particular case the reference was to the latter officer, for in the neighbourhood of the gate stood an important Vigla, or police-station, which is sometimes mentioned instead of the Gate of the Drungarii, as the western limit of the Venetian quarter.[751] The street running eastwards, outside the city wall, was known as the Via Drungariou (De Longario),[752] and the pier in front of the next gate bore the name Scala de Drongario.[753] The practice of storing timber on the shore without the gate has come down from an early period in the history of the city. One of the questions put to Justinian the Great by the Greens, during the altercation between him and the Factions in the Hippodrome, on the eve of the Nika riot was, “Who murdered the timber-merchant at the Zeugma?”[754]—another name for this part of the shore. An inscription on the gate reminded the passing crowd that to remember death is profitable to life (Μνῆμη θανάτου χρησιμεύει τῷ βίῳ).[755] It is in favour of the identification of Zindan Kapoussi with the Gate near the Church of St. John (Porta juxta parvum templum Precursoris) to find only a few yards within the entrance a Holy Well, venerated alike by Christian and Moslem, beside which stood, until recently, the ruins of a Byzantine chapel answering to the small Church of the Forerunner mentioned in the Venetian charters.[756]
