At last, being quite weary with himself, he acknowledged his extreme misery, in a letter to the senate, which begun thus: "What to write to you, Conscript Fathers, or how to write, or what not to write at this time, may all the gods and goddesses pour upon my head a more terrible vengeance than that under which I feel myself daily sinking, if I can tell." Some are of opinion that he had a foreknowledge of those things, from his skill in the science of divination, and perceived long before what misery and infamy would at last come upon him; and that for this reason, at the beginning of his reign, he had absolutely refused the title of the " Father of his Country," and the proposal of the senate to swear to his acts; lest he should afterwards, to his greater shame, be found unequal to such extraordinary honours. This, indeed, may be justly inferred from the speeches which he made upon both those occasions; as when he says, " I shall ever be the same, and shall never change my conduct, so long as I retain my senses; but to avoid giving a bad precedent to posterity, the senate ought to beware of binding themselves to the acts of any person whatever, who might by some accident or other be induced to alter them." And again: " If ye should at any time entertain a jealousy of my conduct, and my entire affection for you, which heaven prevent by putting a period to my days, rather than I should live to see such an alteration in your opinion of me, the title of Father will add no honour to me, but be a reproach to you, for your rashness in conferring it upon me, or inconsistency in altering your opinion of me."

In person he was large and robust; of a stature somewhat above the common size; broad in the shoulders and chest, and proportionable in the rest of his frame. He used his left hand more readily and with more force than his right; and his joints were so strong, that he could bore a fresh, sound apple through with his finger, and wound the head of a boy, or even a young man, with a fillip. He was of a fair complexion, and wore his hair so long behind, that it covered his neck, which was observed to be a mark of distinction affected by the family. He had a handsome face, but it was often full of pimples. His eyes, which were large, had a wonderful faculty of seeing in the night-time, and in the dark, for a short time only, and immediately after awaking from sleep; but they soon grew dim again. He walked with his neck stiff and upright; generally with a frowning countenance, being for the most part silent: when he spoke to those about him, it was very slowly, and usually accompanied with a slight gesticulation of his fingers. All which, being repulsive habits and signs of arrogance, were remarked by Augustus, who often endeavoured to excuse them to the senate and people, declaring that "they were natural defects, which proceeded from no viciousness of mind." He enjoyed a good state of health, without interruption, almost during the whole period of his rule; though, from the thirtieth year of his age, he treated himself according to his own discretion, without any medical assistance.
