(Saints) Martyrs (September 11) (3rd century) Two famous Roman Martyrs, probably brothers, servants or dependents of Saint Eugenia. The weight of evidence is in favour of A.D. 262, in the reign of the Emperor Gallienus, being the year of their death, though some would defer it for about forty years and make Saints Protus and Hyacinth victims of the great persecution under Diocletian. In any case, arrested as Christians, they were scourged and beheaded. In the following century Pope Saint Damasus restored and embellished their shrine, over which verses written by him were inscribed.
