1880  

"In every gallery in Europe there are hideous pictures of blood, carnage, oozing brains, putrefaction—pictures portraying intolerable suffering—pictures alive with every conceivable horror, wrought out in dreadful detail—and similar pictures are being put on the canvas every day and publicly exhibited—without a growl from anybody—for they are innocent, they are inoffensive, being works of art. But suppose a literary artist ventured to go into a painstaking and elaborate description of one of these grisly things—the critics would skin him alive. Well, let it go, it cannot be helped; Art retains her privileges, Literature has lost hers. Somebody else may cipher out the whys and the wherefores and the consistencies of it—I haven't got time."--1601 (1880) by Mark Twain
