Gordos, a titular see in the province of Lydia, suffragan of Sardis. The city is mentioned by Strabo, Hierocles, and Georgius Cyprius. Ptolemy locates it between the River Hermus, the modern Guediz Tchai, and Mt. Sipylus. Lequien (Or. Chris., I, 881) names five of its bishops: John, known to Socrates (Hist. Eccl., VII, xxxvi), and who assisted, at the Council of Ephesus in 431; Theodotus, 458; Theodore, 536; George, 787; and Leo, 878. Between the years 901 and 907, under Leo the Wise (Ecthesis pseudo-Epi-phanii, ed. Gelzer, p. 553), Gordos is always mentioned as a suffragan of Sardis. It is not known when it was suppressed, but it no longer existed in the fifteenth century. Gordos, now Guerdiz, is the chief town of a caza of the sanjak of Saroukhan in the vilayet of Aidin. The city numbers four thousand inhabitants, six hundred of whom are Greek schematics, the remainder being Mussulmans. It is the chief center of the manufacture of Smyrna carpets.
