ON THE THREE BRANCHES OF PERSPECTIVE.
There are three branches of perspective; the first deals with the
reasons of the (apparent) diminution of objects as they recede from
the eye, and is known as Diminishing Perspective.--The second
contains the way in which colours vary as they recede from the eye.
The third and last is concerned with the explanation of how the
objects in a picture ought to be less finished in proportion as
they are remote (and the names are as follows):
Linear Perspective. The Perspective of Colour. The Perspective of
Disappearance.

this passage was written before the year 1490. .
