Image of an Emperor: Claudius

"He was most personable, with a graceful and majestic aspect whether he sat or stood, but especially when he lay in repose; for he was tall, but not thin. His countenance was lively, his grey hair becoming, and he had a round full neck. But his knees were feeble and failed him in walking, so that his gait was unsteady, both when he assumed state and when he was taking diversion. He was indecent and unseemly in his mirth, and especially so in his anger, under the influence of which he foamed at the mouth and discharged from his nostrils. He also stammered in his speech, and had a tremulous motion of the head at all times, but particularly when he engaged in any business, however trifling."

[Suetonius, Claudius, 29]
