Pietro Castelli

Born at Rome, he was graduated in 1617 and studied under the botanist Andrea Cesalpino (1519–1603).

He maintained the necessity for all physicians of studying anatomy, and declared in 1648 that he had dissected more than one hundred corpses.

The Dane Thomas Bartolinus (1616–1680) was led by Castelli's fame to visit him in Messina, in 1644, and speaks of his activity as a publicist.

Among these there is one written in 1653 in answer to inquiries by Hieronymus Bardi of Genoa, wherein Castelli speaks of the cinchona plant and its curative properties in cases of malaria.

Paolo Boccone's pupil Charles Plumier (1646–1704) later perished on his way to South America to learn more of the cinchona.
