(July 1) (Saints) Martyrs (4th century) British Saints, of whom Julius and Aaron suffered at Caerleon-on-Usk, and the rest in different parts of the country, during the persecution under Diocletian (A.D. 303). The general persecution ordered by Imperial authority at that period was carried out with singular mildness by Diocletian’s colleague, the Caesar, Constantius Chlorus, in Britain, yet there can be no doubt that in the attempt at that period to extirpate Christianity, a certain number of the Faithful, like Saint Alban, perished in Britain. Tradition has preserved the names of Julius and Aaron, mentioned both by Gildas and, in his History, by Venerable Bede.
