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

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

This is the excellent foppery of the world: that when we are sick in fortune -- often the surfeits of our own behavior -- we make guilty of our disasters the sun, the moon, and stars, as if we were villains on necessity, fools by heavenly compulsion, knaves, thieves, and treachers by spherical predominance, drunkards, liars, and adulterers by an enforced obedience of planetary influence. An admirable evasion of whoremaster man, to lay his goatish disposition on the charge of a star!
— William Shakespeare

...for until that God who rules all the region of the sky...has freed you from the fetters of your body, you cannot gain admission here. Men were created with the understanding that they were to look after that sphere called Earth, which you see in the middle of the temple. Minds have been given to them out of the eternal fires you call fixed stars and planets, those spherical solids which, quickened with divine minds, journey through their circuits and orbits with amazing speed...
— Marcus Tullius Cicero

The young specialist in English Lit, ... lectured me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong. ... My answer to him was, ... when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.
— spherical quotation by Isaac Asimov
