, that there are two suns; the one the prototype, which
is a fire placed in the other hemisphere, which it totally fills, and
is always ordered in a direct opposition to the reflection of its own
light; and the sun which is visible to us, formed by the reflection of
that splendor in the other hemisphere (which is filled with air mixed
with heat), the light reflected from the circular sun in the opposite
hemisphere falling upon the crystalline sun; and this reflection is
borne round with the motion of the fiery sun. To give briefly the full
sense, the sun is nothing else but the light and brightness of that fire
which encompasseth the earth. Epicurus, that it is an earthy bulk well
compacted, with ores like a pumice-stone or a sponge, kindled by fire.

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.

CHAPTER XXII. WHAT IS THE FIGURE OR SHAPE OF THE SUN.

Anaximenes affirms that in its dilatation it resembles a leaf.
Heraclitus, that it hath the shape of a boat, and is somewhat crooked.
The Stoics, that it is spherical, and it is of the same figure with the
world and the stars. Epicurus, that the recited dogmas may be defended.

CHAPTER XXIII. OF THE TURNING AND RETURNING OF THE STARS, OR THE SUMMER
AND WINTER SOLSTICE.

Anaximenes believes that the stars are forced by a condensed and
resisting air. Anaxagoras, by the repelling force of the northern
air, which is violently pushed on by the sun, and thus rendered more
condensed and powerful. Empedocles, that the sun is hindered from a
continual direct course by its spherical vehicle and by the two
circular tropics. Diogenes, that the sun, when it comes to its utmost
declination, is extinguished, a rigorous cold damping the heat. The
Stoics, that the sun maintains its course only through that space in
which its sustenance is seated, let it be the ocean or the earth; by the
exhalations proceeding from these it is nourished. Plato, Pythagoras,
and Aristotle, that the sun receives a transverse motion
