Landscape is a big thing, and should be viewed from a distance in order
to grasp the scheme of hill and stream. The figures of men and women are
small matters, and may be spread out on the hand or on a table for
examination, when they will be taken in at a glance. Those who study
flower-painting take a single stalk and put it into a deep hole, and
then examine it from above, thus seeing it from all points of view.
Those who study bamboo-painting take a stalk of bamboo, and on a
moonlight night project its shadow on to a piece of white silk on a
wall; the true form of the bamboo is thus brought out. It is the same
with landscape painting. The artist must place himself in communion with
his hills and streams, and the secret of the scenery will be solved....
Hills without clouds look bare; without water they are wanting in
fascination; without paths they are wanting in life; without trees they
are dead; without depth-distance they are shallow; without
level-distance they are near; and without height-distance they are low.
_Kuo Hsi_ (Chinese, eleventh century A.D.).
