EFFECTS OF PERSPECTIVE. 57

Everything, apparently, diminishes, and also
becomes more faint and indistinct, as it recedes
or is placed at a greater distance from the eye;
and the horizon is always on a level with the
eye, consequently, the point of sight is on the
horizon.

Those objects only, which are of regular form,
can be put into perspective by rule; but heights
and widths may be obtained by the same rule.

You see over everything below your eye, as
the ground, which will appear to rise as it
recedes to the horizon, already stated to be
on a level with the height of the eye of the
spectator; therefore, everything growing out of,
or standing upon, the ground, must commence
below the horizon; and in proportion as they



approac h the horizon will they be more distant,
and will require to be made smaller and more
