artist feels to speak distinctly. That necessity must never receive
impulse from a desire to produce an effect on the walls of a gallery:
there is much danger of this working _un_consciously in the accomplished
artist, _consciously_ in the student.

_Watts._

Real effect is making out the parts. Why are we to be told that masters,
who could think, had not the judgment to perform the inferior parts of
art? (as Reynolds artfully calls them); that we are to learn to _think_
from great masters, and to perform from underlings--to learn to design
from Raphael, and to execute from Rubens?

_Blake._


XCVIII

If I knew that my portrait was still at Antwerp, I would have it kept
back for the case to be opened, so that one could see that it had not
been hurt by so long a time spent in a case without being exposed to the
air, and that, as often happens to colours freshly put on, it has not
turned rather yellow, thereby losing all its first effect. The remedy,
if this has happened, is to expose it repeatedly to the sun, the rays of
which absorb the superfluity of oil which causes this change; and if at
any time it still turns brown, it must be exposed afresh to the sun.
Warmth is the only remedy for this serious mischief.
