Astronomy Is Written For Astronomers

Moreover, Since The Sun Remains Stationary, Whatever Appears As A Motion Of The Sun Is Really Due Rather To The Motion Of The Earth.

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.

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. Trismegistus Calls It A "visible God"; Sophocles' Electra, "that Which Gazes Upon All Things." And So The Sun, As If Resting On A Kingly Throne, Governs The Family Of Stars Which Wheel Around.

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

We Are Taught All This [the Motion Of The Earth On Its Axis And Around The Sun] By The Order Of Succession, In Which Those Phenomena (various Planetary Happenings) Follow Each Other, And By The Harmony Of The World, If We Will Only, As The Saying Goes, Look At The Matter With Both Eyes.
