ARCUDIO, PIETRO. – Catholic theologian and controversialist, born in Corfù around 1562, died in Rome in 1633. He was one of the first students of the Greek College of S. Atanasio in Rome. He began his career in the Kingdom of Poland, defending, alongside Pociéj, bishop of Vladimir, the Union of the Ruthenian Church of Brest. On this occasion he published the Antirrhisis (Vilna 1600) against the Calvinist Bronski, Cardinal Bessarione’s pamphlet Sulla processione dello Spirito Santo (Cracovia 1602), and the Iscrizioni of Giovanni Bekkos (Cracovia 1603). Having returned to Rome, he spent his final years there at the Greek College, devoted to composing his works.
Among these, the following may be especially noted: Libri VII de concordia Ecclesiae occidentalis et orientalis in septem sacramentorum administratione, Parigi 1616, 1629; De purgatorio igne adversus Barlaam (published posthumously in a Greek-Latin edition), Roma 1637. He also printed numerous Greek treatises in his collection Opuscula aurea theologica... circa processionem Spiritus Sancti, Roma 1630. E. Legrand cites several other works by A. that remain unpublished, including a Storia dei primi tempi del Collegio greco di Roma and the Storia dell'Unione dei Ruteni.
