Chapter XXXI.—Of Hosius, Bishop of Cordova.
Since we have observed that Hosius the Spaniard was present [at the council of Sirmium] against his will, it is necessary to give some brief account of him. A short time before he had been sent into exile by the intrigues of the Arians: but at the earnest solicitation of those convened at Sirmium, the emperor summoned him thither, wishing that by persuasion, or by compulsion he should give his sanction to their proceedings; for if this could be effected, they considered it would give great authority to their sentiments. On this ground, therefore, as I have said, he was most unwillingly obliged to be present: and when he refused to concur with them, stripes and tortures were inflicted on the old man. Wherefore he was constrained by force to acquiesce in and subscribe to their exposition of the faith. Such was the issue of affairs at that time transacted at Sirmium. But the emperor Constantius after these things still continued to reside at that place, awaiting there the result of the war against Magnentius.
