Ottavio Accoramboni was born in
Rome in the first months of 1549, into a family of
Gubbio. He studied at the
Roman College by the
Jesuits and at the
University of Padua. His younger sister,
Vittoria, married in 1573 Francesco Peretti, a nephew of
Cardinal Montalto, who supported the ecclesiastic career of Ottavio. On 15 May 1579 he was appointed bishop of
Fossombrone in the
Duchy of Urbino. His
episcopal consecration followed on 8 June in the
Sistine Chapel by the hands of cardinal
Benedetto Lomellini. He remained unrelated to the bloody events which involved his sister Vittoria. Ottavio resigned from his bishopric in 1610 and returned to live in Rome. On 4 June 1614, he was appointed
Apostolic Nuncio to Portugal. In Portugal Ottavio supported the action of the Jesuits in the
Far East, and introduced the cult of
Charles Borromeo and
Frances of Rome: in particular on 27 June 1616 he organized a procession by boats from Aldeia Galega to
Lisbon in honor of Saint Charles. The other main effort of Ottavio was to defend the interests of the Church and in particular he opposed the law that required a permit of the king for the ecclesiastics to buy real estates. To sanction violations of the Church's jurisdiction, on 27 June 1617 he imposed a general
interdict in Portugal, which was left only on 30 May of the following year after the intervention of Rome. On 4 June 1620
Vincenzo Landinelli was appointed as Nuncio in his place, but Ottavio remained in Portugal until the end of 1622. On 17 May 1621, he had been appointed
Archbishop of Urbino, however he resigned in 1623 for health problems. He died in Rome on 23 May 1625, and he was buried in the church of
San Gregorio al Celio. On about 1672 his relatives moved his tomb to the new erected family chapel in
Sant'Andrea delle Fratte. ==Episcopal succession==
