First Of All, We Must Note That

If There Should Chance To Be Any Mathematicians Who, Ignorant In Mathematics Yet Pretending To Skill In That Science, Should Dare, Upon The Authority Of Some Passage Of Scripture Wrested To Their Purpose, To Condemn And Censure My Hypothesis, I Value Them Not, And Scorn Their Inconsiderate Judgement. De Revolutionibus Coelestibus

The Universe, Wrought For Us By A Supremely Good And Orderly Creator.

Accordingly, Since Nothing Prevents The Earth From Moving, I Suggest That We Should Now Consider Also Whether Several Motions Suit It, So That It Can Be Regarded As One Of The Planets. For, It Is Not The Center Of All The Revolutions.

Those Who Know That The Consensus Of Many Centuries Has Sanctioned The Conception That The Earth Remains At Rest In The Middle Of The Heavens As Its Center, Would, I Reflected, Regard It As An Insane Pronouncement If I Made The Opposite Assertion That The Earth Moves.

The Two Revolutions, I Mean The Annual Revolutions Of The Declination And Of The Centre Of The Earth, Are Not Completely Equal; That Is The Return Of The Declination To Its Original Value Is Slightly Ahead Of The Period Of The Centre. Hence It Necessarily Follows That The Equinoxes And Solstices Seem To Anticipate Their Timing, Not Because The Sphere Of The Fixed Stars Moves To The East, But Rather The Equatorial Circle Moves To The West, Being At An Angle To The Plane Of The Ecliptic In Proportion To The Declination Of The Axis Of The Terrestrial Globe.
