Plutarch, Caius Gracchus
Bernadotte Perrin, Ed.

18. And yet this Opimius, who was the first consul to exercise the power of a dictator, and put to death without trial, besides three thousand other citizens, Caius Gracchus and Fulvius Flaccus, of whom one had been consul and had celebrated a triumph, while the other was the foremost man of his generation in virtue and reputation—this Opimius could not keep his hands from fraud, but when he was sent as ambassador to Jugurtha the Numidian was bribed by him, and after being convicted most shamefully of corruption, he spent his old age in infamy, hated and abused by the people, [2] a people which was humble and cowed at the time when the Gracchi fell, but soon afterwards showed how much it missed them and longed for them. For it had statues of the brothers made and set up in a conspicuous place, consecrated the places where they were slain, and brought thither offerings of all the first-fruits of the seasons, nay, more, many sacrificed and fell down before their statues every day, as though they were visiting the shrines of gods.
