But Claudius was not an imbecile, although he appeared such to many. Instead, he was, so to speak, a man half-grown, in whom certain parts of the mind were highly developed, but whose character had remained that of a child, timid, capricious, impulsive, giddy, and incapable of self-mastery. In intellect he was learned, even cultivated; he was fond of studies, of history, literature, and archaeology, and spoke and wrote well. But Augustus had been forced to give up the attempt to have him enter upon a political career because he had been unable to make him acquire even that exterior bearing which confers the necessary dignity upon him who exercises great power, to say nothing of the firmness, precision, and force of will required in governing men. Credulous, timorous, impressionable, and at the same time obstinate, gluttonous, and sensual, this erudite, overgrown boy had become in the imperial palace a kind of plaything for everybody, especially for his slaves, who, knowing his defects and his weaknesses, did with him what they wished. He did not lack the intellectual qualities necessary for governing well, but of the moral qualities he had none. He was intelligent, and he looked stupid: he was able to consider the great questions of politics, war, and finance with breadth of view, with original and acute intelligence, but he never succeeded in having himself taken seriously by the persons who surrounded him. He dared undertake great projects, like the conquest of Britain, and he lost his head at the wildest fable about conspiracy which one of his intimates told him; he had mind sufficient to govern the empire as well as Augustus and Tiberius had done, but he could not succeed in getting obedience from four or five slaves or from his own wife. Such a man was destined to turn out a rather odd emperor, at once great and ridiculous. He made important laws, undertook gigantic public works and conquests of great moment; but in his own house he was a weak husband, incapable of exercising any sort of authority over his wife. With these conjugal weaknesses he seriously compromised the imperial authority, while at the same time he was consolidating it and rendering it illustrious with beautiful and wise achievements, especially in the first seven years of his rule, while he lived with Valeria Messalina.
