The shadow or object mirrored in water in motion, that is to say in
small wavelets, will always be larger than the external object
producing it.

It is impossible that an object mirrored on water should correspond
in form to the object mirrored, since the centre of the eye is above
the surface of the water.
This is made plain in the figure here given, which demonstrates that
the eye sees the surface a b, and cannot see it at l f, and at
r t; it sees the surface of the image at r t, and does not see
it in the real object c d. Hence it is impossible to see it, as
has been said above unless the eye itself is situated on the surface
of the water as is shown below [13].
[Footnote: A stands for ochio [eye], B for aria [air], C
for acqua [water], D for cateto [cathetus].--In the original
MS. the second diagram is placed below line 13.]
