16. When, however, Immo and his colleagues reported this to Julian, who was passing the winter at Constantinople, he applied a wise remedy to such a disorder, and sent thither Agilo, the commander of his infantry, an officer in great esteem, that when a man of his rank and reputation appeared there and took the intelligence of the death of Constantius to the army, the siege might be terminated in that way.

After him, Romulus and Sabostius, men who had held high office, being convicted of having sown discord in the empire without any regard to the consequences, were beheaded; and all the rest escaped unpunished,
