In the middle of all is the seat of the Sun. For who in this most beautiful of temples would put this lamp in any other or better place than the one from which it can illuminate everything at the same time. . . . Thus indeed the Sun as if seated on a royal throne governs his household of stars as they circle round him.

Nicholas Copernicus
