Giordano Bruno, orig. Filippo Bruno, (born 1548, Nola, near Naples—died Feb. 17, 1600, Rome), Italian philosopher, astronomer, mathematician, and occultist. He entered a Dominican convent in 1565 and was ordained a priest in 1572. He abandoned the order in 1576 after being accused of heresy. He moved to Geneva in 1578 and thereafter traveled Europe as a lecturer and teacher. Rejecting the traditional geocentric astronomy for a theory even more radical than that of Copernicus, he hypothesized an infinite universe and multiple worlds. His cosmological theories, which anticipated fundamental aspects of the modern conception of the universe, led to his excommunication by the Roman Catholic, Calvinist, and Lutheran churches. In 1592 he was arrested and tried by the Venetian Inquisition, which extradited him to the Roman Inquisition in the following year. After a seven-year trial, he was burned at the stake. His ethical ideas have appealed to modern humanists, and his ideal of religious and philosophical tolerance has influenced liberal thinkers. His most important works are On the Infinite Universe and Worlds (1584) and The Expulsion of the Triumphant Beast (1584).
