Narcissus was employed as a wrestling partner and personal trainer to Commodus in order to train him for his self-indulgent appearances in the Colosseum as a gladiator.
[2][3] In AD 192, several senators, led by Praetorian prefect Quintus Aemilius Laetus, recruited Narcissus to assassinate the emperor after a previous failed attempt by the conspirators.
The poison failed, so Narcissus entered Commodus's bedchamber.
[3] Narcissus was executed during the series of civil wars after Commodus's death.
