The master symbol for handling the cowboy is the symbol of the horseman. The gunman had his place in the mythology of the West, but the cowboy did not realize himself with a gun. Neither did he realize himself with a penis, nor with a bankroll. Movies fault the myth when they dramatize gunfighting, rather than horsemanship, as the dominant skill. The cowboy realized himself on a horse, and a man might be broke, impotent, and a poor shot and still hold up his head if he could ride.
