Ammianus Marcellinus
Ammianus Marcellinus. Ammianus Marcellinus, with an English translation, Vols. I-III. Rolfe, John C., translator. Cambridge, MA; London: Harvard University Press; W. Heinemann, 1935-1940 (printing).
He made great pretensions to learning,[*](Cf. Eusebius, Vita Constantini, iv. 51, Constantinus M. filios omnino probe erudiendos magistris tradiderat peritissimis. Wagner adds e quorum disciplina si quid haesisset, iactare quavis data occasione solebat Constantius; cf. Julian, Orat. i, pp. 28 ff. L.C.L.) but after failing in rhetoric because of dullness of mind, he turned to making verses, but accomplished nothing worth while.
By a prudent and temperate manner of life and by moderation in eating and drinking he maintained such sound health that he rarely suffered from illnesses, but such as he had were of a dangerous character. For that abstinence from dissipation and luxury have this effect on the body is shown by repeated experience, as well as by the statements of physicians.
He was content with little sleep when time and circumstances so required. Throughout the entire span of his life he was so extraordinarily chaste, that not even a suspicion could be raised against him even by an ill-disposed attendant on his private life, a charge which malice, even if it fails to discover it, still trumps up, having regard to the unrestrained liberty of supreme power.
