“He was a very tall man,” wrote Saint-Simon,
well proportioned, rather thin with a roundish face, a broad forehead and handsome, sharply defined eyebrows, a short, but not-too-short nose, large at the end. His lips were rather thick, his complexion a ruddy brown, fine black eyes, large, lively and piercing, and well apart. When he wished, his look was majestic and gracious, at other times it was fierce and severe. He had a nervous, twitching smile which did not come often, but which contorted his face and his whole expression and inspired fear. That lasted but a moment, accompanied by a wild and terrible look, and passed away as quickly. His whole air showed his intellect, his reflection and his greatness, and did not lack a certain grace. He wore only a linen collar, a round brown wig without powder which did not touch his shoulders, a brown tight-fitting coat, plain with gold buttons, a waistcoat, breeches, stockings, and no gloves or cuffs. He wore the star of his order on his coat and the ribbon underneath; his coat was often quite unbuttoned, his hat was always on a table and never on his head even out of doors. With all this simplicity, and in whatever bad carriage or company he might be, one could not fail to perceive the air of greatness that was natural to him.
