Today is the day Giordano Bruno was burned at the stake for his pantheist beliefs.

Bruno (1548-1600) insisted that the earth revolved around the sun, that there are infinite worlds inhabited by intelligent beings, and that the sun is essentially a star. For these and other beliefs, he was burned as a heretic.

Paul Harrison, in his book Elements of Pantheism, suggests taking the day to remember the importance of religious freedom and tolerance.
