Note 024
See the complete narrative of the journey and death of Gallus in Ammianus, l. xiv. c. 11 - Julian complains that his brother was put to death without a trial; attempts to justify, or at least to excuse, the cruel revenge which he had inflicted on his enemies; but seems at last to acknowledge that he might justly have been deprived of the purple.
