Giordano Bruno (Nola, 1548Rome, February 17, 1600) was an Italian philosopher, priest, cosmologist, and occultist. Bruno is known for his system of mnemonics based upon organized knowledge and as an early proponent of the idea of an infinite and homogeneous universe. Burned at the stake as a heretic, Bruno is seen by some as a martyr to the cause of free thought.
One of his "sins" was that he said that the earth revolved around the sun, not the other way around. He was called a heretic and burned alive. We were in Rome in July and saw the statue in the Camp di Fiori. He committed other "sins" and some of them were pretty outrageous. But saying that the earth revolved around the sun, he was correct on that one. At the time the Catholic chrch called that heresy.
