Neil deGrasse Tyson Quotes
Let's find a new way to think about the entire taxonomy of solar system objects, and not clutch to this concept of 'planet,' which, of course, only ever meant, 'Do you move against the background stars, regardless of what you're made of?'

Note that Da Vinci predated Galileo. One big difference was that Da Vinci did not publish his heretical views, but wrote them in his private notebook. The church authorities likely did not know about his heresy.
The Roman Catholic Church had stultified scientific thinking for over a thousand years where differing with accepted church doctrine was not only discouraged but was dangerous. Hicletas—see {590328}—realized that the earth rotated around its own axis three centuries before Christ, and his view was in the literature to which learned people had access. Copernicus later communicated this idea to the Pope but in much more delicate terms—see {590327}. He did not have the problems that Galileo endured with the Church for several reasons. There were different men controlling the church, the printing press had been invented and Galileo published a book that many could read, the Protestant Reformation had really frightened the Church fathers who felt more vulnerable and less tolerant.
