OF THE UP-HILL VIEW.
drawn a faint horizontal line, at its proper height, to
ascertain, by holding up his pencil horizontally on a level
with his eye, what object, or part of an object, appears
on that point of the horizontal line immediately before
him ; the island, for instance, in the above sketch. He
may begin his drawing by representing such object at
that point, and proceeding right and left, on the same
level, to the extremities of his picture. This will greatly
assist in guiding the delineation of the remainder.
OF THE UP-HILL VIEW.
All horizontal planes,—appearing to ascend if they
lie below the horizontal line, and to descend if they lie
above it,—vanish or merge in the horizontal line. So
also all parallel sets of horizontal straight lines, not
parallel to the horizontal line H H, appear to descend, if
they lie above it, or ascend, if they lie below it, to some
point in the horizontal line; in which point they converge
or vanish. Thus in painting, the sea and sky are
considered horizontal planes, and we have already in-
stanced their apparent meeting in the horizontal line.
So again, in representing the interior of a room—the floor
and ceiling (if flat and parallel to one another) appear
to approach each other, and would, if indefinitely pro-
duced, meet or vanish in the horizontal line of the
spectator, as their common vanishing line.
But suppose the ground before the position at E (Fig. 1)
