Eutychianus, surnamed Comazon from his dissipation and buffoonery (τοῦτο γὰρ τοὔνομα ἐκ μίμων καὶ γελωτοποιΐας έ̀σχεν), was originally an actor and dancer at Rome. While serving in Thrace, he was degraded, in consequence of misconduct, to the rank of a rower in the fleet, by Claudius Attalus, governor of the province; but having subsequently taken an active part in the conspiracy against Macrinus, he became the confidential adviser and right-hand man of Elagabalus, was chosen praefect of the praetorium, raised to the rank of consul A. D. 220, twice nominated praefect of the city, and permitted to gratify his revenge by procuring the death of the officer by whom he had been disgraced. Comazon not only escaped the massacre which followed the death of his patron (A. D. 222), but was immediately after appointed praefect of the city for the third time--an honour never before enjoyed by any individual. [GANNYS.]
