Baring-Gould’s sources: The little Roman Martyrology and the Modern one. Ado, Notker, & c. Authority: — Sozomen, Hist. Eeel. iv. 16.] Arsacius, a Persian, was employed in keeping the emperor’s lions, but when he was converted to Christianity he threw up his employment, and witnessed a good confession before Licinius. He then went to Nicomedia and led a monastic life within its walls. There in a vision he was warned to quit the city, as a grievous calamity was about to befall it; he ran at once to the church and besought the clergy to offer supplications to God that His arm might be turned away. But finding that His warnings were not listened to, he cast himself on the ground in the tower which he inhabited, and prayed that he might be spared from seeing the ruin of the city, in which he had first known Christ. Shortly after an earthquake shock occurred, the city was in ruins, timbers falling in the baths and furnaces of workshops caught fire, and the town was in a blaze. Those who escaped fled to the citadel, and there Arsacius was found lying on his face as in prayer, dead. “ All the details about Arsacius," says Sozomen, “ 1 have obtained from persons who heard them stated by those who had seen Arsacius.” S.
