Ancietus, a freedman and preceptor of Nero, and commander of the Praetorian fleet at Cape Misenum, A. D. 59. At Nero's instigation he had a false bottom made for a ship which Agrippina was enticed to visit. She barely escaped drowning, and was soon afterward murdered by x\nicetus at her villa, near the Lucrine lake. Seneca, in his defence of Nero, used Anicetus's story of Agrippina's plots against the emperor's life. Anicetus also professed to have had an intrigue with Octa-via, so as to furnish Nero with a pretext for her banishment. He subsequently lived in luxury in Sardinia with the money given him by Nero in reward for his infamy.
