Alderano Cybo (sometimes Alderano Cibo or Alderano Cybo-Malaspina) (16 July 1613 – 22 July 1700) was an Italian Catholic Cardinal. He served as the Secretary of State of Pope Innocent XI. Early life Cybo was born 16 July 1613 in Genoa, the fifth of fourteen children of Carlo I Cybo-Malaspina, sovereign Prince of Massa and Carrara, and of Brigida Spinola (1587–1660), the daughter of the Marchese di Calice, Giannettino Spinola. As was the custom in his family (he was descended from Pope Innocent VIII and, through his grandmother Marfisa d'Este, from Pope Alexander VI, and was probably Cardinal Innocenzo Cybo's adulterous great-great-grandson), Alderano and several of his siblings were destined for ecclesiastical careers. His elder sister , on the other hand, was married to the Florentine nobleman Jacopo Salviati, but was involved in an obscure episode in 1633, when she was alleged to be behind the savage murder of Caterina Brogi, Jacopo's mistress, whose head was delivered to him in a basket. Veronica was repudiated by her family, but their pressures on Medici government managed to prevent her being prosecuted for the murder. She was forced to leave Florence and to retire to the countryside, near Figline, in the Salviati's . Later she moved to Rome, where she took up residence in the Palazzo Salviati. Ecclesiastical career To pursue his ecclesiastical career, Cybo went to Rome in 1641, as Domestic Prelate and as a referendary of the Tribunal of the Two Signatures to Pope Urban VIII. In 1644 he was appointed master of the Papal Chamber and prefect of the Holy Apostolic Palace. On 6 March 1645, Cybo was elevated to the rank of cardinal by Pope Innocent X, and named Cardinal-Priest of Santa Pudenziana. In 1646 he was given the office of papal legate (i.e. governor) in Urbino, and in 1648 of papal legate in the Romandiola. In 1651 he became legate in Ferrara. On 24 April 1656 he was appointed Bishop of Jesi. The Cardinal held a diocesan synod in Jesi from 4 to 6 July 1658. He resigned the diocese on 10 December 1671, in favor of his brother Lorenzo Cybo. In 1677, Cardinal Cybo was appointed papal legate (governor) in Avignon, which was an exclave of the Papal States in France. He held the office until 1690, though he administered his office only through appointees, never visiting personally. On 6 February 1679 Cybo was appointed suburbicarian
