The so-called Pisonic conspiracy in 65 was the attempt of some senators around Gaius Calpurnius Piso to murder Nero during the festival. According to Tacitus, this project has failed due to the lack of secrecy of some co-operators (see Tac. Ann. 15, 54). So after Nero could be saved from his death shortly before the assassination, after many executions he consecrated a dagger on the Capitol (see Tac. Ann. 15, 74). This piece no longer shows Iupiter as a mere victor over the conspiracy, but increased as a guard over the emperor as a result of this incident.
