XXXII Then Valia, the fourth from Alaric, was made king, and he was an exceeding stern and prudent man. The Emperor Honorius sent an army against him under Constantius, who was famed for his achievements in war and distinguished in many battles, for he feared that Valia would break the treaty long ago made with Athavulf and that, after driving out the neighboring tribes, he would again plot evil against the Empire. Moreover Honorius was eager to free his sister Placidia from the disgrace of servitude, and made an agreement with Constantius that if by peace or war or any means soever he could bring her back to the kingdom, he should have her in marriage. Pleased with this promise, Constantius 165 set out for Spain with an armed force and in almost royal splendor. Valia, king of the Goths, met him at a pass in the Pyrenees with as great a force. Here-upon embassies were sent by both sides and it was decided to make peace on the following terms, namely that Valia should give up Placidia, the Emperor's sister, and should not refuse to aid the Roman Empire when occasion demanded.

But when he had held for a short time the Empire he had seized, he was himself slain at Arelate and his son at Vienne. Jovinus and Sebastian succeeded them with equal presumption and thought they might seize the imperial power; but they perished by a like fate. [Sidenote: VALIA MOVES AGAINST THE VANDALS 427] Now in the twelfth year of Valia's reign the Huns 166 were driven out of Pannonia by the Romans and Goths, almost fifty years after they had taken possession of it. Then Valia found that the Vandals had come forth with bold audacity from the interior of Galicia, whither Athavulf had long ago driven them, and were devastating and plundering everywhere in his own territories, namely in the land of Spain. So he made no delay but moved his army against them at once, at about the time when Hierius and Ardabures had become consuls.
