wonder how the draughtsman was able to make the drawing look
"so real."
The achievement, therefore, of Renaissance perspective was
to codify and systematize a method of bypassing artists' knowl-
edge about shapes and forms. The science of "formal" perspective
provided a means by which they could draw forms just as they
appeared to the eye—including distortions created optically by a
form's position in space relative to the viewer's eye.
The system worked beautifully and solved the problem
of how to create an illusion of deep space on a flat surface, of
re-creating the visible world. Dürer's simple device evolved into
a complicated mathematical system, enabling artists from the
Renaissance onward to overcome their mental resistance to
optical distortions of the true shapes of things and to draw
realistically.
Formal perspective versus "informal" perspective
But the system of formal perspective is not without problems.
Followed to the letter, strictly applied perspective rules can result
in rather dry and rigid drawings. Perhaps the most serious prob-
lem with the formal perspective system is that it is so "left-
brained." It employs the style of left-hemisphere processing:
analysis, sequential logical cogitation, and mental calculations
within a pre-prescribed system. There are vanishing points, hori-
zon lines, perspective of circles and ellipses, and so on. The sys-
tem is detailed and cumbersome, the antithesis of R-mode style
with its antic/serious, pleasurable quality. For example, in any-
thing but the simplest one-point perspective setup (Figure 8-10),
vanishing points may be several feet beyond the edge of the
drawing paper, requiring pins and strings to mark them.
Fortunately, once you understand "informal" perspective
(sighting), you don't really need to know formal perspective at all.
That's not to say the study of perspective is not useful and inter-
esting. In my view, knowledge never hurts! But sighting is suffi-
cient for basic drawing skills.
Graham Collier, professor of art,
states that in the early days of the
inception and development of
Renaissance perspective it was
used creatively and imaginatively
to impart what must have been a
thrilling sense of space to art.
"Effective as perspective is, how-
ever, it becomes a deadening
influence on an artist's natural way
of seeing things once it is accepted
as a system—as a mechanical
formula."

Fig. 8-10. The classic perspective
illustration. Note that vertical lines
remain vertical; horizontal edges
converge at a vanishing point (or
points) on the horizon line (which
is always at the artist's eye level).
That's one-point perspective in a
nutshell. Two-point and three-
point perspective are complex sys-
tems, involving multiple vanishing
points that often extend far beyond
the edges of the drawing paper and
requiring a large drawing table,
T-squares, straight-edges, etc., to
draw. Informal sighting is much
easier and is sufficiently accurate
for most drawing.
