“It is said that he was tall, of a fair complexion, round limbed, rather full faced, with eyes black and piercing; and that he enjoyed excellent health, except towards the close of his life, when he was subject to sudden fainting-fits, and disturbance in his sleep. He was likewise twice seized with the falling sickness while engaged in active service." -Gaius Suetonius Tranquillus: The Lives Of The Twelve Caesars, section XLV
