Giordano Bruno

Giordano Bruno (/dʒɔːrˈdɑːnoʊ ˈbruːnoʊ/ jor-DAH-noh BROO-noh; Italian: [dʒorˈdaːno ˈbruːno]; Latin: Iordanus Brunus Nolanus; born Filippo Bruno; February 1548 – 17 February 1600) was a Neopolitan philosopher, Dominican friar and priest, poet, alchemist, astronomer, cosmological theorist, and esotericist. He is known for his cosmological theories, which conceptually extended to include the then-novel Copernican model. He practised Hermeticism and took a mystical approach to exploring the universe. He proposed that the stars were distant suns surrounded by their own planets (exoplanets), and he raised the possibility that these planets might foster life of their own, a cosmological position known as cosmic pluralism. He also insisted that the universe is infinite and can have no centre.

Bruno was tried for heresy by the Roman Inquisition on charges of denial of several core Catholic doctrines, including eternal damnation, the Trinity, the deity of Christ, the virginity of Mary, and transubstantiation. Bruno's pantheism was not taken lightly by the church, nor was his teaching of metempsychosis regarding the reincarnation of the soul. The Inquisition found him guilty, and he was burned at the stake in Rome's Campo de' Fiori in 1600. After his death, he gained considerable fame, being particularly celebrated by 19th- and early 20th-century commentators who regarded him as a martyr for science. Some historians are of the opinion that his heresy trial was not a response to his cosmological views but rather a response to his views on religion and the afterlife, while others largely reject this view. Bruno's case is still considered a landmark in the history of free thought and the emerging sciences.
