1568 – 1644
Pope Urban VIII (1568–1644), born Maffeo Barberini, served as pope from 1623 to 1644 and was a significant figure in Counter-Reformation Catholicism. He is best known philosophically and historically for his role in the trial of Galileo Galilei in 1633, which became a landmark case in the conflict between religious authority and emerging scientific methodology. His theological interests included the nature of prophecy and martyrdom within the Catholic tradition.
