FROM WHENCE TO DEPICT A LANDSCAPE

Landscapes should be represented so that the trees may be half in
light and half in shadow; but it is better to do them when the sun
is covered with clouds, for then the trees are lighted by the
general light of the sky, and the general darkness of the earth. And
then they are darkest in certain parts in proportion as those parts
are nearest to the middle of the tree and to the earth.

444.

OF TREES TO THE SOUTH.

When the sun is in the east the trees to the South and to the North
have almost as much light as shadow. But a greater share of light in
proportion as they lie to the West and a greater share of shadow in
proportion as they lie to the East.

OF MEADOWS.

If the sun is in the East the verdure of the meadows and of other
small plants is of a most beautiful green from being transparent to
the sun; this does not occur in the meadows to the West, and in
those to the South and North the grass is of a moderately brilliant
green.

445.

OF THE 4 POINTS OF THE COMPASS [IN LANDSCAPES].

When the sun is in the East all the portions of plants lighted by it
are of a most lively verdure, and this happens because the leaves
lighted by the sun within the half of the horizon that is the
Eastern half, are transparent; and within the Western semicircle the
verdure is of a dull hue and the moist air is turbid and of the
colour of grey ashes, not being transparent like that in the East,
which is quite clear and all the more so in proportion as it is
moister.

The shadows of the trees to the East cover a large portion of them
and are darker in proportion as the foliage of the trees is thicker.

446.

OF TREES IN THE EAST.

When the sun is in the East the trees seen towards the East will
have the light which surrounds them all round their shadows,
excepting on the side towards the earth; unless the tree has been
pruned [below] in the past year. And the trees to the South and
North will be half in shade and half in light, and more or less in
shade or in light in proportion as they are more or less to the East
or to the West.

The [position of] the eye above or below varies the shadows and
lights in trees, inasmuch as the eye placed above sees the tree with
the little shadow, and the eye placed below with a great deal of
shadow.

The colour of the green in plants varies as much as their species.

447.

OF THE SHADOWS IN TREES.

The sun being in the East [to the right], the trees to the West [or
left] of the eye will show in small relief and almost imperceptible
gradations, because the atmosphere which lies between the eye and
those trees is very dense [Footnote 7: _per la 7a di questo_. This
possibly referred to something written on the seventh page of this
note book marked _G_. Unfortunately it has been cut out and lost.],
see the 7th of this--and they have no shade; for though a shadow
exists in every detail of the ramification, it results that the
images of the shade and light that reach the eye are confused and
mingled together and cannot be perceived on account of their
minuteness. And the principal lights are in the middle of the trees,
and the shadows to wards the edges; and their separation is shown by
the shadows of the intervals between the trees; but when the forests
are thick with trees the thin edges are but little seen.

448.

OF TREES TO THE EAST.

When the sun is in the East the trees are darker towards the middle
while their edges are light.

The effects of midday light.

449.

OBJECTS IN HIGH LIGHT SHOW BUT LITTLE, BUT BETWEEN LIGHT AND SHADOW
THEY STAND OUT WELL.
