1548 – 1600
Giordano Bruno (1548–1600) was an Italian Dominican friar, philosopher, and cosmological theorist whose radical ideas extended Copernican heliocentrism into a vision of an infinite universe populated by countless worlds. Drawing on Neoplatonism, Hermeticism, and early Renaissance naturalism, he challenged both Aristotelian cosmology and orthodox theology. He was tried by the Roman Inquisition for heresy and burned at the stake in Rome in 1600.
