Philosopher and cosmologist Giordano Bruno was born Filippo Bruno in 1548 in Nola (Campania, then part of the Kingdom of Naples), the son of a soldier. He was educated in Naples. He entered the Dominican Order at the age of seventeen, but quickly began to hold heretical opinions. He eventually left his monastery, fled the Inquisition, and travelled throughout Europe. He moved to London in 1583 as a guest of the French ambassador. There he became acquainted with the poet Philip Sydney (to whom he dedicated two books). During his stay, Bruno completed his most important works, the six so-called Italian Dialogues. They were published in London by John Charlewood at the Half-Eagle & Key in the Barbican. Bruno’s controversial views and tactless language lost him the support of friends. He left England for France in 1586. In 1589 he returned to Italy where he was denounced by the Inquisition. He spent eight years in prison and was burnt at the stake in 1600.
