Herodian wrote that Perennis began to plot against Commodus. Gifts from his newly acquired fortune were to curry favor with the army and his sons were secretly recruiting additional forces in anticipation of the coming revolt. Before they could act, however, the plot was exposed. First, during a public festival honoring
Capitoline Jupiter, an unknown person took the stage before the performers and warned the emperor and the assembled crowd of Perennis' plans. He wasn't believed, and Perennis had him executed. Later, a group of soldiers came to Commodus and relayed the details of the plot, and showed him coins with Perennis' portrait that they had stolen from one of prefect's sons. The emperor had him and his sons executed. Also instrumental in Perennis' downfall was
Marcus Aurelius Cleander, who would go on to fulfill a similar role in the next period of Commodus's reign. ==References==
