- Nicolaus Copernicus

We regard it as a certainty that the earth, enclosed between poles, is bounded by a spherical surface.

- Nicolaus Copernicus

So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

- Nicolaus Copernicus

Those things which I am saying now may be obscure, yet they will be made clearer in their proper place.

The earth together with its surrounding waters must in fact have such a shape as its shadow reveals, for it eclipses the moon with the arc of a perfect circle.

- Nicolaus Copernicus

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.

- Nicolaus Copernicus

First of all, we must note that the universe is spherical.

- Nicolaus Copernicus

In so many and such important ways, then, do the planets bear witness to the earth's mobility.

- Nicolaus Copernicus

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.

- Nicolaus Copernicus

The earth also is spherical, since it presses upon its center from every direction.

- Nicolaus Copernicus

So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.

- Nicolaus Copernicus

Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.

- Nicolaus Copernicus

Therefore, when I considered this carefully, the contempt which I had to fear because of the novelty and apparent absurdity of my view, nearly induced me to abandon utterly the work I had begun.

- Nicolaus Copernicus

The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.

- Nicolaus Copernicus

I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected.

- Nicolaus Copernicus

Yet if anyone believes that the earth rotates, surely he will hold that its motion is natural, not violent.

- Nicolaus Copernicus

Pouring forth its seas everywhere, then, the ocean envelops the earth and fills its deeper chasms.

- Nicolaus Copernicus
