Which philosopher was burned at the stake in 1600 partly for advocating heliocentrism?

Giordano Bruno was burned at the stake in 1600 after advocating ideas that included heliocentrism.

Bruno was an Italian philosopher, former Dominican friar, and cosmological thinker who supported an infinite universe containing many worlds. He accepted aspects of Copernican astronomy and argued that the stars could be distant suns with their own planets.

The Roman Inquisition condemned Bruno as a heretic, and he was executed in Rome’s Campo de’ Fiori on February 17, 1600. His trial involved many theological charges, including his views on the Trinity, Christ’s divinity, the soul, and transubstantiation. Historians therefore caution against describing his death as punishment for heliocentrism alone; cosmological ideas were one part of a much broader religious dispute.

Bruno is often incorrectly portrayed as a straightforward scientific martyr. Unlike Galileo, he was not primarily an observational astronomer, and his cosmology combined Copernican ideas with metaphysics, magic, and speculation about infinite worlds.
