Letters 94.66

Do you think that Gaius Marius, who was once consul (he received this office on one occasion, and stole it on all the others) courted all his perils by the inspiration of virtue when he was slaughtering the Teutons and the Cimbri, and pursuing Jugurtha through the wilds of Africa? Marius commanded armies, ambition Marius.
