ACQUAVIVA, OTTAVIO, junior. – Cardinal, born in Naples in 1608, died in Rome in 1674. He served as Governor of Jesi (1638), Orvieto (1642), and Ancona (1643), defending the latter two cities against attacks by the Farnese during the War of Castro.
Summoned to Rome by Innocent X, he was appointed Secretary of the Congregation of Waters before returning to administrative governance first of the Patrimony and then of Castro. Elevated to the purple in March 1654 with the title of S. Bartolomeo all'Isola, which he later changed to that of S. Cecilia, he was soon assigned to govern the legation of Bologna, where he remained until 1658. In that city, he received Christina of Sweden in 1655 during her journey to Rome.
