Cato the Younger

We are told that from his very childhood Cato displayed, in speech, in countenance, and in his childish sports, a nature that was inflexible, imperturbable, and altogether steadfast. He set out to accomplish his purposes with a vigour beyond his years, and while he was harsh and repellent to those who would flatter him, he was still more masterful towards those who tried to frighten him. It was altogether difficult to make him laugh, although once in a while he relaxed his features so far as to smile; and he was not quickly nor easily moved to anger, though once angered he was inexorable.
