o quantity of labor would obtain
the real surface of a tress of Apollo's hair, and the full expression of
his mouth. So that we are compelled at once to call the imagination to
help us, and say to it, _You_ know what the Apollo Chrysocomes must be
like; finish all this for yourself. Now, the law under which imagination
works, is just that of other good workers. "You must give me clear
orders; show me what I have to do, and where I am to begin, and let me
alone." And the orders can be given, quite clearly, up to a certain
point, in form; but they cannot be given clearly in color, now that the
subject is subtle. All beauty of this high kind depends on harmony; let
but the slightest discord come into it, and the finer the thing is, the
more fatal will be the flaw. Now, on a flat surface, I can command my
color to be precisely what and where I mean it to be; on a round one I
cannot. For all harmony depends, first, on the fixed proportion of the
color of the light to that of the relative shadow; and therefore if I
fasten my color, I must fasten my shade. But on a round surface the
shadow changes at every hour of the day; and therefore all coloring
which is expressive of form, is impossible; and if the form is fine,
(and here there is nothing but what is fine,) you may bid farewell to
color.

141. Farewell to color; that is to say, if the thing is to be seen
distinctly, and you have only wise people to show it to; but if it is to
be seen indistinctly, at a distance, color may become explanatory; and
if you have simple people to show it to, color may be necessary to
excite _their_ imaginations, though not to excite yours. And the art is
great always by meeting its conditions in the straightest way; and if it
is to please a multitude of innocent and bluntly-minded persons, must
express itself in the terms that will touch them; else it is not good.
And I have to trace for you through the history of the past, and
possibilities of the future, the expedients used by great sculptors to
obtain clearness, impressiveness, or splendor; and the manner of their
appeal to the people, under various light and shadow, and with reference
to different degrees of public intelligence: such investigation
resolving itself again and again, as we proceed, into questions
absolutely ethical; as, for instance, whether color is to be bright or
dull,--that is to say, for a populace cheerful or heartless;--whether it
is to be delicate or strong,--that is t
