Gian Matteo Giberti  Gian Matteo Giberti (20 September 1495 – 30 December 1543) was an Italian diplomat, Bishop of Verona. Born at Palermo, he was the natural son of Francesco Giberti, a Genoese naval captain. In 1513 he was admitted to the household of Cardinal Giulio de' Medici, and advanced so rapidly in Latin and Greek that he soon became an eminent member of the Academia Romana. Later he was appointed the cardinal's secretary, and Pope Leo X, with whom he had political dealings, valued his opinions and advice. In 1521 he was chief intermediary with the envoy of Emperor Charles V. He used his influence over the pope to protect and help struggling men of letters. He led a severely religious life, and was a member of the Oratory of Divine Love (Sodalitium Divini Amoris) of St. Cajetan and Cardinal Carafa (future pope Paul IV). After his ordination to the priesthood, and the death of Leo X, he was sent by Cardinal Giulio, his patron, on a mission to Charles V, and returned to Rome with the new pope, Adrian VI. Pope Clement VII, immediately after his election, made him Datario (1523), and in 1524, at the request of the Doge of Venice, he was appointed Bishop of Verona. Being obliged, against his will, to remain in Rome, he had himself represented at Verona by a vicar-general. Giberti was chosen a member of the Consilium de Emendanda Ecclesia, the reform committee decreed by Paul III, but political events soon put an end to these labours. At Pavia (1525) he tried to make peace between Francis I of France and Charles V. It was at his prompting that Clement VII espoused the cause of France; the League of Cognac (22 May 1526) was also his work. After the Sack of Rome (1527) he was put in prison and barely escaped death. He succeeded in making his escape, and went to Verona (1528) intending to devote himself to his diocese. He was done with politics, all the more because the pope had gone over to the imperial cause. However, he appeared from time to time in the Curia. Pope Paul III recalled him to Rome for the work of the Reform Committee; among other missions he was sent to Trent to make preparations for the council.
