AN
ESSAY
ON
PERSPECTIVE.

CHAP. I.
Definitions.

1. PERSPECTIVE teaches us
the Manner of Delineating by
Mathematical Rules; that is, it
ſhews us how to draw geometri-
cally upon a Plane, the Repre-
ſentations of Objects according
to their Dimenſions and different Situations; in
ſuch manner, that the ſaid Repreſentations pro-
duce the ſame Effects upon our Eyes, as the Ob-
jects whereof they are the Pictures.
