Perpenna, accordingly, having now more accomplices in his attempt upon Sertorius, brought into their number Manlius also, one of those in high command. This Manlius was enamoured of a beautiful boy, and as a mark of his affection for him told him of the conspiracy, bidding him neglect his other lovers and devote himself to him alone, since within a few days he was to be a great personage. But the boy carried the tale to another one of his lovers, Aufidius, to whom he was more devoted.
And Aufidius, on hearing the story, was astounded; for though he himself was a party to the conspiracy against Sertorius, he did not know that Manlius was. But since the boy mentioned by name Perpenna, Gracinus, and sundry others of those whom Aufidius knew to be among the conspirators, Aufidius was confounded, and after making light of the story to the boy and exhorting him to despise Manlius as an empty braggart, he himself went to Perpenna, told him of the sharpness of the crisis and of their peril, and urged him to attempt the deed. The conspirators were persuaded, and after providing a man to act as the bearer of letters, they introduced him to Sertorius.
