MANNUCCHI, Ubaldo. — Patrologist and canonist, born at Montagano (Campobasso) on 8 Nov. 1883, died at Rome on 20 May 1935. He studied at the Roman Seminary, obtaining the degree in theology and in utroque iure at the Apollinare. He was professor of patrology at the Augustinian College of S. Monica in Rome.
He published: Irenaei Lugdunensis adv. Haereses libri 5, in Bibliotheca sanctorum Patrum, by G. Vizzini, Rome 1907: text left incomplete. Following the prohibition of Rauschen’s manual of patrology, he composed, with the help of his favourite pupil, Fr Antonio Casamassa O.S.A., Istituzioni di patrologia ad uso delle scuole teologiche (2 vols., Rome 1914–15): after the author’s death Casamassa kept the two volumes updated, reaching a 6th ed. (21st thousand). He translated various works from German, including L. Fonck, Il metodo del lavoro scientifico (Rome 1909), and composed many others; he also compiled the patrology bulletin for the Rivista storico-critica delle scienze teologiche.
Appointed Auditor of the Sacred Roman Rota, he supervised the edition of several volumes of the Decisiones S. R. Rotae and for many years directed the Acta Apostolicae Sedis, leaving unpublished the index for its first 25 years, which is preserved, though only in part, among his heirs.
