Note 108
The first military acts of the reign of Jovian are related by Ammianus (xxv. 6), Libanius (Orat. Parent. e. 143, p. 364), and Zosimus (1. iii. [c. 30] p. 189, l90, 19l ). Though we may distrust the fairness of Libanius, the ocular testimony of Eutropius (uno a Persis atque altero proelio victus, x. 17 [9]) must incline us to suspect that Ammianus has been too jealous of the honour of the Roman arms.
