Rodolfo Pio da Carpi, Italian cardinal (died 1564)

Rodolfo Pio di Savoia, often referred to as Rodolfo Pio da Carpi, was an Italian cardinal, humanist and patron of the arts. The nephew of a diplomat, he himself became a diplomat by the age of thirty, and came to know both Emperor Charles V and King Francis of France, and he negotiated with both on behalf of the pope. His uncle, Alberto III Pio, was Pico della Mirandola's maternal nephew, had been educated by Aldus Manutius and had become a noted humanist scholar. These associations formed Rodolfo's background and education. He formed a notable library and participated in the humanist studies of 16th-century Rome; he also served on the Roman Inquisition. He helped to establish the Inquisition at Milan.
