DATIUS, REATRIUS (RESTIUS) and OTHERS (Saints) Martyrs (January 27) (5th or 6th century) African Martyrs who suffered under the Vandals. These barbarians under Genseric invaded Africa (A.D. 427), the Roman Provinces having been betrayed to them by Count Boniface, the Governor, who, afterwards penitent, vainly sought to stay their progress. Hippona, the city of Saint Augustine, fell in the year 431, that next after the death of the holy Doctor; and Carthage was taken A.D. 437. The Vandals professed Arianism and persecuted the Catholics cruelly and persistently. The persecution, begun in 427, became more sanguinary under King Hunneric (477-485) and cannot be said to have ceased before A.D. 534, when the famous leader Belissarius recovered for the Emperor Justinian the Roman Provinces of Africa and extinguished the Vandal Kingdom. Of the earlier phases of the persecution we have particulars from the pen of the contemporary historian, Victor Vitensis. Procopius may also be referred to. The time, precise place, and circumstances of the martyrdom of Saint Datius and his fellow sufferers are unknown.
