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.
