Chapter XXI.

Of the Magnitude of the Sun.

Anaximander says, that the sun itself in greatness is equal to the earth, but that the circle from whence it receives its respiration and in which it is moved is seven and twenty times larger than the earth. Anaxagoras, that it is far greater than Peloponnesus. Heraclitus, that it is no broader than a man's foot. Epicurus, that he equally embraceth all the foresaid opinions - that the sun may be of magnitude as it appears, or it may be somewhat greater or somewhat less.
