Bishop Stefano (1295) is the first prelate of whom there is mention. The Chapter of the Cathedral already existed in the 13th century. The Chapter maintained its right to elect a new bishop until 1338.[4] The Chapter was composed of six dignities (the Archdeacon, the Dean, the Cantor, the Treasurer, the Archpriest, and the Ecclesiarch-Theologian) and fourteen Canons.[5]
In 1472 the see was united to that of Gerace, under Bishop Athanasius Calceofilo, by whom the Greek Rite was abolished, although it remained in use in a few towns.
In 1536 Oppido became again an independent see, under Bishop Pietro Andrea Ripanti; among other bishops were Antonio Cesconi (1609) and Giovanni Battista Montani (1632), who restored the cathedral and the episcopal palace; Bisanzio Fili (1696), who founded the seminary; Michele Caputo (1852), who was transferred to the See of Ariano, where it is suspected that he poisoned King Ferdinand II; eventually, he apostatized.
In 1748 the town of Oppido is estimated to have had 2,000 inhabitants.[6] The town was heavily damaged by the earthquakes of 1783, in the first of which Oppido was at the epicenter,[7] and the population decimated by the plague that followed.[8]
