painter are usually those which have been done quickly, and in the heat
of the first thought, on a large scale, for places where there was
little likelihood of their being well seen, or for patrons from whom
there was little prospect of rich remuneration. In general, the best
things are done in this way, or else in the enthusiasm and pride of
accomplishing some great purpose, such as painting a cathedral or a
camposanto from one end to the other, especially when the time has been
short, and circumstances disadvantageous.
