Sertorius (14.1-14.2)

In consequence of these successes Sertorius was admired and loved by the Barbarians, and especially because by introducing Roman arms and formations and signals he did away with their frenzied and furious displays of courage, and converted their forces into an army, instead of a huge band of robbers.

Still further, he used gold and silver without stint for the decoration of their helmets and the ornamentation of their shields, and by teaching them to wear flowered cloaks and tunics, and furnishing them with the means to do this, and sharing their love of beautiful array, he won the hearts of all. But most of all were they captivated by what he did with their boys. Those of the highest birth, namely, he collected together from the various peoples, at Osca, a large city, and set over them teachers of Greek and Roman learning; thus in reality he made hostages of them, while ostensibly he was educating them, with the assurance that when they became men he would give them a share in administration and authority.
