The Walls on the Side of the Continent have six Gates; one within the Palace of _Constantine_, another, which is call’d the _Adrianopolitan_ Gate, and a third on the Brow of the seventh Hill. Besides these, there is the _Porta Aurea_ or _Gilded Gate_, the Gate of _Selymbria_ or _Rhegium_, and the Gate of the seven Towers. On the Side of the Bay _Ceras_ is the Gate of the _Blachernæ_, at present call’d _Xyloporta_, seated near the third Angle of the City. There are also the Gates call’d _Cynigos_, or _Porta Palatina_, _Phanaria_, _Agia_, _Porta Jubalica_, _Farinaria_, _Lignaria_, _Seminaria_, _Piscaria_, the Gate of the _Neorium_, and the Gate of _Demetrius_, which stands on the Ridge of the first Hill. On the Side of the _Propontis_ there are about five; every one of which has _Stairs_, or a _Landing-place_, and a Haven for Ships, besides the Gates of the Imperial Palace. There is also the _Porta Stercoraria_, _Leonina_, _Condescala_, two of which stand at the Foot of the seventh Hill. Those which have been principally taken Notice of by Historians, are the Gates of _Cynigos_, _Rhegium_ and _Xylocerum_, also the Gate of _Eugenius_, the _Porta Aurea_, that call’d _Myriandros_, the _Porta Condescala_, and _Porta Carsiana_. In old _Byzantium_ there was the _Thracian Gate_. For we are told by _Dion_, that the seven Towers reach’d from the _Thracian_ Gate to the Sea, which _Cedrinus_ tells us was the Bay _Ceras_. If any one spoke any thing in the first of these Towers, it immediately flew to the second, and so through all the rest, so that you might hear the Voice distinctly repeated in every one of them. _Pliny_ tells the very same Story of _Cyzicus_. In that City, says he, near the _Thracian_ Gate there are seven Towers, which multiply the Voice by Repetition, or Reiteration, more than seven times. This, he adds, was look’d upon by the _Grecians_ as somewhat miraculous, and was call’d the _Echo_. I never found any Mention made of the _Thracian_ Gates in any Historian but in _Pliny_, though it is not altogether improbable, that there were such Gates there; for _Apollonius_, in the _first Book_ of his _Argonauticks_, mentions the _Thracian_ Haven in _Cyzicus_; and _Plutarch_ is very express, that near this City there was a Street call’d the _Thracian Street_. This is also attested not only by some more modern Writers of _Constantinople_, but also by _Dion_ and _Xenophon_; the latter of whom writes, That when _Alcibiades_ appear’d before the Town, the _Byzantians_ open’d the _Thracian_ Gates to him of their own Accord.
