Gainsborough was a fashionable portrait-painter. He never painted
anything or anybody that any Englishman of the day could not have
seen and in his turn observed "from the life." And yet he was as
much a fantastic as William Blake in his way. He did not see his
sitters, or only saw them in a trance: a very mild, superficial
trance, but nevertheless a palpable one. The fancies that hung
round them, the flavour of their lives, their illusions about
themselves, or about each other, all went to his head as they
floated into his studio to be painted, like some enervating
bergamot. He was doped with the graceful existence of all these
pretty people, and that is how he worked. He saw nothing but pale
blue cliches, and never a man or woman. Blake's Jehovah is a far
realler person, or at least you can imagine him in the Tottenham
Court Road more readily.
