7.16

As he was holding the assizes at Nova Carthago, he learned of the rebellion of the Gallic provinces through an urgent appeal for help from the governor of Aquitania; then came letters from Vindex, calling upon him to make himself the liberator and leader of mankind. So without much hesitation he accepted the proposal, led by fear as well as by hope. For he had intercepted dispatches ordering his own death, which had been secretly sent by Nero to his agents. He was encouraged too, in addition to most favorable auspices and omens, by the prediction of a young girl of high birth, and the more so because the priest of Jupiter at Clunia, directed by a dream, had found in the inner shrine of his temple the very same prediction, likewise spoken by an inspired girl two hundred years before. And the purport of the verses was that one day there would come forth from Hispania the ruler and lord of the world. (Galba 9)

[H]e cut off the hands of a money-lender who carried on his business dishonestly and nailed them to his counter; crucified a man for poisoning his ward, whose property he was to inherit in case of his death; and when the man invoked the law and declared that he was a Roman citizen, Galba, pretending to lighten his punishment by some consolation and honor, ordered that a cross much higher than the rest and painted white be set up, and the man transferred to it. But he gradually changed to sloth and inaction, not to give Nero any cause for jealousy, and as he used to say himself, because no one could be forced to render an account for doing nothing. (Suetonius, Galba 9)
