The Holy Martyrs Pamphilius the Presbyter, Valens the Deacon, Paul, Porphyrius, Seleucius, Theodulus, Julian, Samuel, Elias, Daniel, Jeremiah and Isaiah suffered during the persecution against Christians, initiated by the emperor Diocletian in the years 308-309 at Caesarea in Palestine.
The young Julian, a native of Cappadocia who had come to Caesarea, saw the bodies of the saints which had been thrown to wild beasts without burial. Julian went down on his knees and venerated the bodies of the sufferers. Soldiers standing by at the wall seized him and took him to the governor, who condemned him to burning. The bodies of all twelve martyrs remained unburied for four days, but neither beasts nor birds would touch them. Embarrassed by this situation, the pagans permitted Christians to take the bodies of the martyrs and bury them.
