Sulla (12.7-12.8)

But these were lawful commanders of men who were self-restrained and had learned to serve their leaders without a murmur, and they were themselves kingly in spirit and simple in their personal expenses, and indulged in moderate and specified public expenditures, deeming it more disgraceful to flatter their soldiers than to fear their enemies;

the generals of this later time, however, who won their primacy by force, not merit, and who needed their armies for service against one another, rather than against the public enemy, were compelled to merge the general in the demagogue, and then, by purchasing the services of their soldiers with lavish sums to be spent on luxurious living, they unwittingly made their whole country a thing for sale, and themselves slaves of the basest men for the sake of ruling over the better. This was what drove out Marius, and then brought him back again against Sulla; this made Cinna the assassin of Octavius, and Fimbria of Flaccus.[*]
