 The first Bishop of Muro Lucano of whom there is mention was Leo (1049).Its bishop Antonio (1376) became a partisan of the antipope Clement VII; he was therefore driven by Carlo of Durazzo to seek refuge at Polsino, whereupon Clement VII suppressed the Diocese of Muro.In 1418, however, Guiduccio de Porta was appointed to this see; he was learned in civil and canon law; among his successors were Flavio Orsini (1560), who became a Cardinal; the poet Gian Carlo Coppola (1643), who later became Bishop of Gallipoli, his native town; Alfonso Pacello (1674), founder of a congregation of priests for the care of the sick of the diocese.
