 Third-century Geminius died shortly before Saint Cyprian; a Donatist Florentinus attended a conference in 411; and a Simeon was at the Council of Carthage (525).Simeon belonged to Furnos Maior, but it is uncertain of which town the other two were bishops.Victor of Vita recounts that in the persecution by the Vandals of Genseric in 430 or 431 Bishop Mansuetus of Urusi was martyred by being burned alive at the gate of Urusi known as the "Porta Fornitana", the 'Furnos Gate'.
