At in Bithynia Valentinianus princeps (ut praediximus) declaratus, dato in perendinum diem signo proficiscendi, convocatis primoribus, quasi tuta consilia, quam sibi placentia, secuturus, percunctabatur, quemnam ad imperii consortium oporteret assumi, silentibusque cunctis, Dagalaifus tunc equestris militiae rector, respondit fidentius: Si tuos amas inquit, imperator optime, habes fratrem; si rem publicam, quaere quem vestias.
Now Valentinian was chosen emperor in Bithynia (as we have said before). He gave the signal for the march for the next day but one, and assembling the chief civil and military officials, as if ready to follow safe and sound advice rather than his own inclination, inquired who ought to be chosen as partner in the rule. When all the rest were silent, Dagalaifus, at that time commander of the cavalry, boldly answered: If you love your relatives, most excellent emperor, you have a brother; if it is the state that you love, seek out another man to clothe with the purple.
