The foundation of the See of Corinth is attributed to the Apostle Paul, who is held to have preached in the city and addressed multiple epistles to the Corinthian Church, two of which became canon.
[2] In the Roman and early Byzantine periods, Corinth was the capital and metropolitan see of the province of Achaea (southern Greece).
[3] Based on the various Notitiae Episcopatuum from the 10th–12th centuries, Corinth counted seven suffragan sees: Cephalonia, Zakynthos, Damala, Lacedaemon/Monemvasia, Argos, Helos and Zemena.
[4] In 1203/4, the city fell to the ambitious lord of the Argolid, Leo Sgouros, who secured possession of Corinth by inviting its Metropolitan, Nicholas, to Acronauplia for dinner, and then had him thrown from its heights.
[1] Although Corinth was the oldest and most prestigious see in southern Greece, during the period of Frankish rule it was eclipsed by the Latin Archbishopric of Patras.
