What I like about this quote is the use of his mind in an analytical manner to explain what should be "the obvious"!
"The Bible shows the way to go to heaven, not the way the heavens go." [Having proposed the heliocentric world view] - Galileo Galilei
Make sure you run your mouse over the photo of Gallileo's manuscript for lots of info!
It was on this page that Galileo Galilei first noted an observation of the moons of Jupiter. This observation upset the notion that all celestial bodies must revolve around the Earth. Galileo published a full description in Sidereus Nuncius in March 1610.
In 1614, from the pulpit of Santa Maria Novella, Father Tommaso Caccini denounced Galileo's opinions on the motion of the Earth, judging them dangerous and close to heresy.
In 1616, Cardinal Roberto Bellarmino personally handed Galileo an admonition enjoining him neither to advocate nor teach Copernican astronomy.
In 1633 Galileo was ordered to stand trial on suspicion of heresy. He was ordered imprisoned; the sentence was later commuted to house arrest, where he remained until his death.
