AGUCCHI, GIROLAMO. - Cardinal, brother of the preceding, b. in 1554, d. in Rome on 17 Apr. 1605. In the service of his uncle, Card. Filippo Sega, he followed him to France and actively collaborated with him in the negotiations conducted by the latter, on behalf of Pope Clement VIII,
in order to uphold, together with the interests of the League, those of the Catholic religion. Having returned to Rome in 1594, he became there auditor and referendary to Card. Pietro Aldobrandini; he then received the preceptory of S. Spirito in Sassia and was finally, on 9 June 1604, raised to the purple, with the title of S. Pietro in Vincoli, where he is buried. He was an active collaborator, especially in French affairs, of Pope Leone XI, but he was not his Secretary of State, as some maintain.
