The strength and majesty which were conspicuous in the person of that general, marked him, in the popular opinion, as a candidate worthy of the throne, which he afterwards ascended.

In the familiar intercourse of private life, his manners were cheerful and engaging; nor would he sometimes disdain, in the license of convivial mirth, to vie with the pantomimes themselves, in the exercises of their ridiculous profession.

But when the trumpet summoned him to arms; when he mounted his horse, and, bending down (for such was his singular practice) almost upon the neck, fiercely rolled his large animated eyes round the field, Constantius then struck terror into his foes, and inspired his soldiers with the assurance of victory.
He had received from the court of Ravenna the important commission of extirpating rebellion in the provinces of the West; and the pretended emperor Constantine, after enjoying a short and anxious respite, was again besieged in his capital by the arms of a more formidable enemy.
Yet this interval allowed time for a successful negotiation with the Franks and Alemanni and his ambassador, Edobic, soon returned at the head of an army, to disturb the operations of the siege of Arles.

The Roman general, instead of expecting the attack in his lines, boldly and perhaps wisely, resolved to pass the Rhone, and to meet the Barbarians.
His measures were conducted with so much skill and secrecy, that, while they engaged the infantry of Constantius in the front, they were suddenly attacked, surrounded, and destroyed, by the cavalry of his lieutenant Ulphilas, who had silently gained an advantageous post in their rear.

The remains of the army of Edobic were preserved by flight or submission, and their leader escaped from the field of battle to the house of a faithless friend; who too clearly understood, that the head of his obnoxious guest would be an acceptable and lucrative present for the Imperial general.
