The use of such a title, even as it appears under the reign of Constantine, is a strange and unconnected fact, which can scarcely be admitted on the joint authority of Imperial medals and contemporary writers.
The whole empire was deeply interested in the education of these five youths, the acknowledged successors of Constantine.

The exercise of the body prepared them for the fatigues of war and the duties of active life.

Those who occasionally mention the education or talents of Constantius, allow that he excelled in the gymnastic arts of leaping and running that he was a dexterous archer, a skilful horseman, and a master of all the different weapons used in the service either of the cavalry or of the infantry.

The same assiduous cultivation was bestowed, though not perhaps with equal success, to improve the minds of the sons and nephews of Constantine.

The most celebrated professors of the Christian faith, of the Grecian philosophy, and of the Roman jurisprudence, were invited by the liberality of the emperor, who reserved for himself the important task of instructing the royal youths in the science of government, and the knowledge of mankind.
