Italian Philosopher Giordano Bruno Is Burnt at the Stake

Giordano Bruno was a controversial Renaissance figure. An uncompromising freethinker who ventured far beyond the bounds of religious doctrine, he was never long out of trouble, and he was finally burned at the stake by the Inquisition on February 17, 1600. Today many regard Bruno as a martyr, and in some respects he was: he defended the Copernican theory and even proposed a universe that might contain an infinitude of worlds, and these propositions contributed to his demise. But Renaissance science was hardly distinct from magic, and Bruno was also involved in a quest for secret, occult knowledge that would allow a master magician to control all nature. Ultimately, Bruno most resembles a hero of science in his stubborn refusal to limit his own speculative thinking, however odd it sometimes was, to suit religious authority, and his contention that intellectual inquiry operated on a different plane from religious truth.

Bruno was born Filippo Bruno in Nola near Naples, Italy, sometime in January 1548. He became a Dominican monk as a youth and took the name Giordano when he entered the order. He questioned traditional Church doctrines and read banned books by Erasmus and other humanists. Bruno left the Dominicans in 1576 to avoid charges of heresy and left Naples to avoid prosecution. For the next several decades he would be constantly on the move. He had little trouble attracting patrons, but his controversial views and abrasive personality always got him into trouble, and he could never stay in one place for long. Bruno moved from France to England to Germany, writing various works on magic, human memory, science, and religion. He considered Jesus to have been a “master magician” and believed that the universe contained infinite worlds filled with infinite diversities of life, of which God was the universal soul. These views, as expressed in his book On the Infinite Universe and Worlds (1584), ran counter to traditional Christian teachings that the earth was the center of the universe. So did his defense of the Copernican Sun-centered, or heliocentric, model of the solar system in The Ash Wednesday Supper (1584).

Bruno returned to Italy in 1591 at the invitation of Giovanni Moncenigo, his latest prospective patron, a nobleman in Venice. Predictably, Bruno had a falling-out with him, and in 1592 Moncenigo denounced Bruno to the local church authorities in charge of the Inquisition in Venice. They held Bruno until February 1593, when he was turned over to the central authorities in Rome. There he was imprisoned for over six years until he was finally tried and convicted of heresy. Refusing to recant, Bruno was handed over to the secular authorities for his punishment, which consisted of being burnt at the stake at Campo de Fiori on February 17, 1600.

For many years Bruno's memory languished in obscurity, but his works never disappeared, and they had an influence on the intellectual development of later philosophers, including Spinoza. In 19th-century Italy, Bruno became the idol of self-professed freethinkers, who in 1889 dedicated a statue to him on the site of his execution. Annual festivities are held there every February 17 in his honor.
