He was a man who left many proofs of noble self-confidence worthy of imitation by sensible men, one who never deviated from the principles of a fearless nature, but was always firm andresembled the laws, which, as we know, in the manifold cases in court speak with one and the same voice; ¹ and he then remained truer to the side of justice which he had espoused, even when the emperor, becoming arbitrary, assailed him with threats when he gave him good advice.
