proportion as the eye is more natural and nearer to the plane, and
as the part of the plane on which it is figured is farther from the
eye.
And let this plane be d e on which are seen 3 equal circles which
are beyond this plane d e, that is the circles a b c. Now you
see that the eye h sees on the vertical plane the sections of the
images, largest of those that are farthest and smallest of the
nearest.

Here follows what is wanting in the margin at the foot on the other
side of this page.
Natural perspective acts in a contrary way; for, at greater
distances the object seen appears smaller, and at a smaller distance
the object appears larger. But this said invention requires the
spectator to stand with his eye at a small hole and then, at that
small hole, it will be very plain. But since many (men's) eyes
endeavour at the same time to see one and the same picture produced
by this artifice only one can see clearly the effect of this
perspective and all the others will see confusion. It is well
therefore to avoid such complex perspective and hold to simple
perspective which does not regard planes as foreshortened, but as
much as possible in their proper form. This simple perspective, in
