Giordano Bruno, the Renaissance mystic who was burned alive as a heretic in Rome’s Campo de’ Fiori during the Inquisition. Bruno was a provocative subject for historians, undoubtedly from a Catholic perspective. Bruno believed the universe was infinite and populated by many worlds. He thought the sun was just one of an endless number of independently moving heavenly bodies, and he was the first man to state stars seen at night were identical to the Sun. Bruno also agreed with Copernicus that the Earth moved.
