These events, from the principate of the emperor Nerva to the death of Valens, I, a former soldier and a Greek, have set forth to the measure of my ability, without ever (I believe) consciously venturing to debase through silence or through falsehood a work whose aim was the truth. The rest may be written by abler men, who are in the prime of life and learning. But if they chose to undertake such a task, I advise them to forge[*](For procudere, cf. xv. 2, 8 (ingenium); xxx. 4, 13 (ora); Horace, Odes, iv. 15, 19.) their tongues to the loftier style.
Diocletian ruled with Herculius[*](This name was conferred on Maximianus by Diocletian.) Maximianus for twenty years.
Constantius,[*](Constantius Chlorus, father of Constantine, emperor 305–306.) grandson of the brother of that best of emperors Claudius,[*](Claudius II.; his mother was Claudia, daughter of Crispus, brother of Claudius II; cf.

Abr. 2307.) was first one of the emperor’s bodyguard, then a tribune, and later, governor of Dalmatia.[*](Under the emperor Carus, who wished to make him Caesar in place of his own brother Carinus.) With Galerius he was appointed Caesar by Diocletian[*](In 292.) ; for he put away his former wife Helena and married Theodora, daughter of Maximianus, by whom he afterwards had six children,[*](Three sons: Dalmatius, Julius Constantius, and Hannibalianus; and three daughters: Constantia, Anastasia, and Eutropia.) brothers of Constantine. But by his former wife Helena he already had a son Constantine, who was later the mightiest of emperors.
