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.

For It Is The Duty Of An Astronomer To Compose The History Of The Celestial Motions Through Careful And Expert Study.

Therefore I Would Not Have It Unknown To Your Holiness, The The Only Thing Which Induced Me To Look For Another Way Of Reckoning The Movements Of The Heavenly Bodies Was That I Knew That Mathematicians By No Means Agree In Their Investigation Thereof.

In The Center Of All Rests The Sun. For Who Would Place This Lamp Of A Very Beautiful Temple In Another Or Better Place That This Wherefrom It Can Illuminate Everything At The Same Time? As A Matter Of Fact, Not Unhappily Do Some Call It The Lantern; Others, The Mind And Still Others, The Pilot Of The World.

For The Fact That It Is Not The Centre Of All Revolutions Is Made Clear By The Apparent Irregular Motion Of The Wandering Stars, And Their Variable Distances From The Earth, Which Cannot Be Understood In A Circle Having The Same Centre As The Earth.
