Small objects close at hand and large ones at a distance, being seen
within equal angles, will appear of the same size.

PERSPECTIVE.

There is no object so large but that at a great distance from the
eye it does not appear smaller than a smaller object near.

95.

Among objects of equal size that which is most remote from the eye
will look the smallest. [Footnote: This axiom, sufficiently clear in
itself, is in the original illustrated by a very large diagram,
constructed like that here reproduced under No. 108.

The same idea is repeated in C. A. I a; I a, stated as follows:
_Infra le cose d'equal grandeza quella si dimostra di minor figura
che sara piu distante dall' ochio_.--]

Why an object is less distinct when brought near to the eye, and why
with spectacles, or without the naked eye sees badly either close or
far off [as the case may be].
