The Third Military Gate is but a short distance from the Gate of the Pegè, being situated between the fourth and fifth towers to the north. To the rear of the entrance was the quarter called the Triton (τὸ Τρίτον),[322] and, more commonly, the Sigma (Σίγμα);[323] the latter designation being derived, probably, from the curve in the line of the walls immediately beyond the gate. What precisely was the object of the curve is not apparent. One authority explains it as intended for the accommodation of the courtiers and troops that assembled here on the occasion of an Imperial visit to the Pegè.[324] But the Theodosian Walls were built before the Pegè came into repute;[325] and the visits of the emperors to the Holy Spring were not so frequent or so important as to affect the construction of the walls in such a manner. In the quarter of the Sigma stood a column, bearing the statue of Theodosius II., erected by Chrysaphius.[326] And there, in the riot of 1042, the Emperor Michael Calaphates and his uncle Constantine were blinded, having been dragged thither from the Monastery of Studius, where they had sought sanctuary.[327] The most noted churches in the quarter were dedicated respectively to the Theotokos,[328] St. Stephen, and St. Isaacius.[329] The site of the first is, in the opinion of Dr. Paspates, marked by the remains of an old Byzantine cistern off the street leading from the Guard-house of Alti Mermer to the Mosque of Yol Getchen.[330] [Illustration: The Gate of Rhegium.] The next public gate, Yeni Mevlevi Haneh Kapoussi, situated between the tenth and eleventh towers north of the Third Military Gate, was known by two names, Porta Rhegiou (Ῥηγίου),[331] the Gate of Rhegium, and Porta Rhousiou (τοῦ Ῥουσίου),[332] the Gate of the Red Faction. That it bore the former name is established by the fact that the inscription in honour of Theodosius II. and the Prefect Constantine, which was placed, according to the Anthology, on the Gate of Rhegium, is actually found on the lintel of this entrance.[333] The name alluded to Rhegium (Kutchuk Tchekmedjè), a town twelve miles distant, upon the Sea of Marmora, whither the road leading westward conducted. The title of the gate to the second name rests partly upon the consideration that the name cannot be claimed for any other entrance in the walls, and partly upon the fact that two circumstances connected with the gate can thus be satisfactorily explained. In the first place, the seven shafts employed to form the lintel, posts, and sill of the gateway are covered with red wash, as though to mark the entrance with the colour of the Red Faction. Secondly, on the northern face of the southern gateway-tower is an inscription, unfortunately mutilated, such as the Factions placed upon a structure in the erection of which they were concerned. The legend as preserved reads thus: “The Fortune of Constantine, our God-protected Emperor triumphs....”
