Felix of Thibiuca

Felix (d. 303) was a bishop of Thibiuca in Africa who was martyred during the Great Persecution under the Roman emperor Diocletian alongside Audactus, Fortunatus, Januarius, and Septimus. Felix is said to have resisted the command of the local magistrate Magnillian (Magnillianus) to surrender his church's copies of the Christian scriptures.

In one account, Felix and the others were taken to Carthage and decapitated on July 15. These Five Martyrs of Carthage were venerated in the basilica of St Faustus. Another placed his martyrdom at Venosa in Italy. His companions may have been deacons but, apart from their joint martyrdom with Felix, are now unknown. Their feast day was observed jointly on October 24.

Felix was formerly honored as the patron saint of Venosa.
