A titular see of Macedonia, suffragan of Thessalonica
Paroecopolis, a titular see of Macedonia, suffragan of Thessalonica. It is mentioned by Ptolemy (III, 13, 30) as being in Sintice, a part of Macedonia, and by Phlegon "Fragm. histor. gr." ed. Didot, III, 609). Hierocles (Synecdemus, 639, 8) and Constantine Porphyrogenitus (De thematibus, 2) call it Parthicopolis, but the second locates it in Thrace. Stephanus Byzantius calls it Parthenopolis and relates according to Theagenes the legend of its foundation by Geraestus, son of Mygdon, said to have named the city in honor of his two daughters. Pliny (IV, xi) has the same name, but places it in Thrace. Its bishop, Jonas or John, assisted at the Council of Sardica (342 or 343); at the Council of Chalcedon (451) there was present John "Parthicopolis prima Macedonia" (Le Quien, "Oriens christianus", II, 75). This see is not mentioned in any of the Greek "Notitiae episcopatuum"
