Oh, hey, I found the full Lafayette quote! "To Potsdam I went to make my bow to the king, and notwithstanding what I had heard of him, could not help being struck with the dress and appearance of an old, broken, dirty corporal, covered all over with Spanish snuff, with his head almost leaning on one shoulder, and fingers almost distorted by the gout; but what surprises me much more is the fire, and sometimes the softness, of the most beautiful eyes I ever saw, which give as charming an expression to his physiognomy, as he can take a rough and threatening one at the head of his troops."

This is 1785, just a year before Fritz died--possibly from all that snuff-taking. I would love to see a portrait of Old Fritz that depicts the state of his clothes, but I guess that's too much realism even for him. :P I just keep running across it in like every description of a foreign visitor. Nobody can pass by him in their memoirs without mentioning that he's covered in snuff. (I guess it's memorable when you start sneezing as you approach him, which at least one visitor accused him of.)
