When the two nephews of Constantine, Gallus and Julian, were saved from the fury of the soldiers, the former was about twelve, and the latter about six, years of age; and, as the eldest was thought to be of a sickly constitution, they obtained with the less difficulty a precarious and dependent life, from the affected pity of Constantius, who was sensible that the execution of these helpless orphans would have been esteemed, by all mankind, an act of the most deliberate cruelty. 11 Different cities of Ionia and Bithynia were assigned for the places of their exile and education; but as soon as their growing years excited the jealousy of the emperor, he judged it more prudent to secure those unhappy youths in the strong castle of Macellum, near Cæsarea. The treatment which they experienced during a six years’ confinement, was partly such as they could hope from a careful guardian, and partly such as they might dread from a suspicious tyrant. 12 Their prison was an ancient palace, the residence of the kings of Cappadocia; the situation was pleasant, the buildings stately, the enclosure spacious. They pursued their studies, and practised their exercises, under the tuition of the most skilful masters; and the numerous household appointed to attend, or rather to guard, the nephews of Constantine, was not unworthy of the dignity of their birth. But they could not disguise to themselves that they were deprived of fortune, of freedom, and of safety; secluded from the society of all whom they could trust or esteem, and condemned to pass their melancholy hours in the company of slaves devoted to the commands of a tyrant who had already injured them beyond the hope of reconciliation. At length, however, the emergencies of the state compelled the emperor, or rather his eunuchs, to invest Gallus, in the twenty-fifth year of his age, with the title of Cæsar, and to cement this political connection by his marriage with the princess Constantina. After a formal interview, in which the two princes mutually engaged their faith never to undertake any thing to the prejudice of each other, they repaired without delay to their respective stations. Constantius continued his march towards the West, and Gallus fixed his residence at Antioch; from whence, with a delegated authority, he administered the five great dioceses of the eastern præfecture. 13 In this fortunate change, the new Cæsar was not unmindful of his brother Julian, who obtained the honors of his rank, the appearances of liberty, and the restitution of an ample patrimony. 14
