His troops crossed the Euphrates in force, and, marching on Antioch, once more captured that unfortunate town, from which the more prudent citizens had withdrawn, but where the bulk of the people, not displeased at the turn of affairs, remained and welcomed the conqueror.

Miriades was installed in power, while Sapor himself, at the head of his irresistible squadrons, pressed forward, bursting "like a mountain torrent" into Cilicia and thence into Cappadocia.

Tarsus, the birthplace of St.Paul, at once a famous seat of learning and a great emporium of commerce, fell; Cilicia Campestris was overrun; and the passes of Taurus, deserted or weakly defended by the Romans, came into Sapor's hands.

Penetrating through them and entering the champaign country beyond, his bands soon formed the siege of Caesarea Mazaca, the greatest city of these parts, estimated, at this time to have contained a population of four hundred thousand souls.

Demosthenes, the governor of Caesarea, defended it bravely, and, had force only been used against him, might have prevailed; but Sapor found friends within the walls, and by their help made himself master of the place, while its bold defender was obliged to content himself with escaping by cutting his way through the victorious host.
