Sidyma, a titular see in Lycia, suffragan of Myra; mentioned by Ptolemy, V, 3, 5; Pliny, V, 28; Hierocles, 684, 15; Stephanus Byzantinus, s.v., Cedrenus (ed. Bonn) 344. Near the sea and to the west of Patara it was built on the southern slope of Cragus, to the northwest of the estuary of the Xanthus. Its history is unknown; its ruins, which prove it to have been an unimportant place, are near the village of Doodoorgar, in the vilayet of Koniah, and consist of a theatre, agora, temples, tombs, and some inscriptions. Le Quien, “Oriens christianus”, I, 973, mentions three of its bishops: Hypatius, who signed the letter of the bishops of Lycia to the Emperor Leo, 458; Zemarchus, at the councils of Constantinople in 680 and 692; Nicodemus, at Nicea, 787; Eustathius, present at the Council of Seleucia, 359, was bishop both of Pinara and of Sidyma (see Le Quien, ibid., 975). The see is mentioned by the Greek “Notitiae epiacopatuum” until the thirteenth century.
