teeth, which are generally shown although so seldom seen, but always
apparent if the mouth is felt (see diagram A). This is, I think, a fair
type of the first drawing the ordinary child makes--and judging by some
ancient scribbling of the same order I remember noticing scratched on a
wall at Pompeii, and by savage drawing generally, it appears to be a
fairly universal type. It is a very remarkable thing which, as far as I
know, has not yet been pointed out, that in these first attempts at
drawing the vision should not be consulted. A blind man would not draw
differently, could he but see to draw. Were vision the first sense
consulted, and were the simplest visual appearance sought after, one
might expect something like diagram B, the shadows under eyes, nose,
mouth, and chin, with the darker mass of the hair being the simplest
thing the visual appearance can be reduced to. But despite this being
quite as easy to do, it does not appeal to the ordinary child as the
other type does, because it does not satisfy the sense of touch that
forms so large a part of the idea of an object in the mind. All
architectural elevations and geometrical projections generally appeal to
this mental idea of form. They consist of views of a building or object
that could never possibly be seen by anybody, assuming as they do that
the eye of the spectator is exactly in front of every part of the
building at the same time, a physical impossibility. And yet so removed
from the actual visual appearance is our mental idea of objects that
such drawings do convey a very accurate idea of a building or object.
And of course they have great advantage as working drawings in that they
can be scaled.
