The stars
are wheel-shaped masses of air, full
of fire, breathing out flames from pores
in different partsÉ. The sun has the
highest position of all, the moon is
next in order, and under it are the fixed
stars and planetsÉ. The circle of
the sun is 28 times as large as the earth,
like a chariot wheel, having a hollow
center and this full of fire, shining in
every part, and sending out fire
through a narrow opening like the air from a
flute.
