This went on for some years with slight interruptions, and then there was a complete change. It was apparently about the year 344, when Julian would be thirteen or fourteen years old, and Gallus eighteen or nineteen, that, by the Emperor's orders, the two brothers were carried away to Macellum, an imperial castle in the mountain districts of Cappadocia. There they spent the next six years of life in strict retirement. What may have been the reason of this change we are not told, but we can easily suspect. Gallus was now growing up to manhood. He was tall, well made, and handsome, with flowing auburn hair; not unlike his uncle, the great Constantine, as we may infer from the description of the two men. The suspicious temper of Constantius might take alarm lest this young man should become the centre of disaffection and treason. But, however this may be, the seclusion was complete. Julian speaks of it as banishment. To himself it was the worst kind of banishment. He was banished not only from the city and the court, about which probably he knew little and cared less, but he was banished also from his books and his teachers. The two brothers saw no one of their own rank; their domestics were their only associates. Gallus was no companion for Julian. He had no literary taste; notwithstanding his handsome looks he was coarse and violent, even ferociously brutal, in his disposition, as the sequel shows. The treatment of Julian during this critical period of his life must have been altogether injurious to the healthy development of his character. A cramped boyhood almost certainly produces a one-sided manhood.
