Esta história de Viriato [as anteriores estavam incluídas em artigos relativos aos livros em que foram surgindo] provém do breviário de Eutrópio:
About the same time Metellus had singular success against the Spaniards in Celtiberia. Quintus Pompeius succeeded him. Not long after Quintus Caepio was also sent to the same war, which a leader named Viriathus was still keeping up against the Romans in Lusitania; through fear of whom Viriathus was killed by his own men. after he had kept Spain in a state of excitement against the Romans for fourteen years. He was at first a shepherd, then captain of a band of robbers, and at last he stirred up so many powerful nations to war, that he was considered as the protector of Spain against the Romans. When his assassins asked a reward of the consul Caepio, they received for answer, that "it was never pleasing to the Romans, that a general should be killed by his own soldiers."
