三世紀危機
Unlike many of the would-be emperors and rebels who vied for imperial power during the Crisis of the Third Century of the Roman Empire, Valerian was of a noble and traditional senatorial family. Details of his early life are sparse, except for his marriage to Egnatia Mariniana, with whom he had two sons: later emperor Publius Licinius Egnatius Gallienus and Licinius Valerianus.
