The axis of this garden in
Siena exploits single-point
perspective. The garden walk
is terminated at one end by
a gateway and at the other
by a formal flowerbed.

An understanding of perspective
allows complex subjects such
as this double bow-fronted

drawn with confidence. Notice
how windows in the distance
are rendered as mere vertical
lines, and the use of hatching
focuses the eye on the critical
parts of the design.
