Anaximander thinks that she gives light to herself, but it is very
slender and faint. Antiphon, that the moon shines by its own proper
light; but when it absconds itself, the solar beams darting on it
obscure it. Thus it naturally happens, that a more vehement light puts
out a weaker; the same is seen in other stars. Thales and his followers,
that the moon borrows all her light of the sun. Heraclitus, that the
sun and moon are after the same manner affected; in their configurations
both are shaped like boats, and are made conspicuous to us by receiving
their light from moist exhalations. The sun appears to us more
refulgent, by reason it is moved in a clearer and purer air; the moon
appears more duskish, it being carried in an air more troubled and
gross.
