To draw closer to the Emperor, let us first examine his appearance. Picturing his facial features is not an easy proposition since none of the portraits can be trusted to show his true likeness. Dubbed "small puss in boots" by Josephine, Napoleon was not actually as short as legend has led us to believe. At 1.69m tall (roughly five and a half feet), he was the average height for his time. All of the known measurements agree to within a few millimeters, including post mortem measurements taken by the doctor on Saint Helena who recorded a height of 5 pieds, 2 pouces, 4 lignes (equivalent to 1.686m or five feet 5.5 inches).
Bonaparte was slim at the time of the Revolution but grew fatter with age and fortune. As Emperor, he got shorter and wider and hated it. He had a rather high and prominent forehead, with brown hair thinning around the temples--fine, soft hair, albeit in short supply. He often changed his hairstyle. From the Consulate onward he is depicted with short neck-length hair. In Italy he had long free-flowing hair, loosely gathered in a pigtail. When he cut his hair, Napoleon acquired the look that is now part of legend. His soldiers, always quick to notice what their leader did, immediately nicknamed him Petit Tondu ("little shaveling"). Napoleon being the only general of the time who eschewed the fashion for thick, flowing locks.
A "piercing gaze that went right through you" is how people described meeting Napoleon's steely blue-gray eyes. Being short-sighted, he sometimes needed opera glasses to see properly and always kept a pair about his person. In his desk he kept a pair of eyeglasses and pince-nez.
Napoleon had a finely drawn mouth, with evenly proportioned lips that shut tight when he was in a bad mood but opened in a broad smile when he was being charming. His teeth were not particularly straight but very white and in very good condition.
Napoleon had an aquiline profile with a nose worthy of an ancient Greek bust. An irreproachable nose in every way, so very sensitive that vinegar and Agarwood had to be burnt in the Emperor's bedchamber.
The head under the hat was on the large side, 22 pouces (inches) in circumference. It was long rather than wide with slightly flattened temples and very sensitive to the touch. His ears were "small and perfectly formed". His neck was short, his shoulders were rounded and his chest was broad and largely hairless. His legs were well turned and shapely thighs. His hands were also very beautiful and always protected by kid gloves or gloves made of reindeer leather, thicker gloves when he went horseback riding. Despite habitually biting his nails when impatient or preoccupied, Napoleon took great care of his hands like every other aspect of his appearance.
Napoleon had a strong voice, no doubt a product of army life, but he was incapable of singing in tune. He loved to sing just the same would often be heard humming or whistling to himself when he was in a good mood, particularly as he got dressed in the morning. Not content merely to murder popular ditties, Napoleon also murdered the French language. He often made mistakes when speaking, such as failing to make the liasion between a consonant and a vowel, or adding the letter "t" to the third person singular or the letter "s" to the first person singular in the future tense. Did he speak with a strong Corsican/Italian accent? History doesn't say. All we know for sure is that he spoke with an Italian-like intonation, placing the stress on the final syllable.
