(1548-February 17, 1600)
Italian philosopher, priest, astronomer/astrologer, and occultist.
Bruno is perhaps best known for his system of mnemonics and as an early proponent of the idea of extra-solar planets and extraterrestrial life.
Burned at the stake as a heretic for his theological ideas, Bruno is seen as a martyr to the cause of free thought.
