Poppæus Sabinus was continued in his government of the province of Moesia with the addition of Achaia and Macedonia. It was part of Tiberius' character to prolong indefinitely military commands and to keep many men to the end of their life with the same armies and in the same administrations. Various motives have been assigned for this. Some say that, out of aversion to any fresh anxiety, he retained what he had once approved as a permanent arrangement; others, that he grudged to see many enjoying promotion. Some, again, think that though he had an acute intellect, his judgment was irresolute, for he did not seek out eminent merit, and yet he detested vice. From the best men he apprehended danger to himself, from the worst, disgrace to the State. He went so far at last in this irresolution, that he appointed to provinces men whom he did not mean to allow to leave Rome.
