Thus I undertook to explain in it reasonably fully only
what I understood about light and, at the same time, to add something
about the sun and the fixed stars, because most light results from them;
about the skies, because they transmit the light; about the planets,
comets and the earth, because they reflect it; and in particular about
all the bodies that are on earth, because they are either coloured,
transparent or luminous; and, finally, about human beings, because
they are the perceivers of light.
