Helius (died 69) was a prominent freedman in the time of ancient Roman Emperor Nero.
[4] Without Nero's knowledge, the murder was planned through the treachery of Agrippina because Silanus was the son of a great-grandson of Augustus.
The murder was performed by Publius Egnatius Celer, a Roman knight, and Helius, men who had the charge of the emperor's domains in Asia.
[5] Nero became more and more insulated by flatterers and more convinced of his musical talents, committed to go to Greece and neglected Helius' warnings about disaffection at home, which would rise to a climax with the Vindex's rebellion.
During this period, Cassius Dio reports that Helius had Quintus Sulpicius Camerinus Pythicus executed because he refused to give up the name Pythicus, which Helius claimed was an insult against Nero's victory in the Pythian Games.
