Meteorology By Aristotle

But this too is impossible. For if the eye and the mirror and the
whole of the object were severally at rest, then the same part of
the image would appear at the same point in the mirror. But if the
mirror and the object move, keeping the same distance from the eye
which is at rest, but at different rates of speed and so not always
at the same interval from one another, then it is impossible for the
same image always to appear in the same part of the mirror. Now the
constellations included in the circle of the milky way move; and so
does the sun, the object to which our sight is reflected; but we stand
still. And the distance of those two from us is constant and uniform,
but their distance from one another varies. For the Dolphin sometimes
rises at midnight, sometimes in the morning. But in each case the
same parts of the milky way are found near it. But if it were a reflection
and not a genuine affection of these this ought not to be the case.

Again, we can see the milky way reflected at night in water and similar
mirrors. But under these circumstances it is impossible for our sight
to be reflected to the sun.

These considerations show that the milky way is not the path of one
of the planets, nor the light of imperceptible stars, nor a reflection.
And those are the chief theories handed down by others hitherto.
