 In the fourth year, the death of Trocondus was discovered, and Illus, enraged at the deceit practised on him by Pamprepius, put him to death.The fort was soon after taken by the treachery of Trocondus's brother-in-law, who had been sent for the purpose from Constantinople by Zeno, and Illus and Leontius were beheaded (488) and their heads sent to the emperor.Tillemont and Le Beau regard the revolt of Illus as an attempt to re-establish paganism, but for this view there seems no foundation.
