Pisonian conspiracy

The plot reflected the growing discontent among the ruling class of the Roman state with Nero's increasingly despotic leadership, and as a result is a significant event on the road toward his eventual suicide and the chaos of the Year of the Four Emperors which followed.

[citation needed] Gaius Calpurnius Piso, a leading Roman statesman, benefactor of literature, and orator, intended to have Nero assassinated, and replace him as emperor through acclamation by the Praetorian Guard.

[citation needed] The conspiracy was put in jeopardy by a woman named Epicharis, who divulged parts of the plan to Volusius Proculus, commanding a fleet in Misenum.

[citation needed] On the morning that the conspirators' plot was to be carried out[6] – 19 April – a freedman named Milichus informed on his former master Flavius Scaevinus after receiving orders to sharpen a knife and prepare bandages.

[7] Tacitus attributes his decision to give his former master up to greed and avarice at the urging of his wife,[8] reporting it to Nero's secretary, Epaphroditus.

Gold coin of AD 65/66, with the figure of Salus (public safety), most likely struck to celebrate the suppression of the plot.
Silver denarius of AD 67/68. The reverse reads IVPPITER CVSTOS , " Jupiter the guardian," probably referring to Nero's having survived the plot against him. [ 12 ]
