The biographies in this volume comprise the concluding part of the Scriptores Historiae Augustae.
Their main subjects are the events of the Roman Empire during the years 235-284.
These were the days of the so called Illyrian Caesars on the throne of Rome. The Empire was compelled in those days to face too often and too dangerous incursions of barbarians, as well as tireless efforts of various provincials trying to free themselves from Roman mastery.
Rome was forced to recruit more and more barbarians to fill up the ranks of her soldiery and officers. Rome even experienced a strong shortage of silver and gold metals to coin her Denarii and Aurei. These deficiencies revealed Rome's weakness abroad and caused disquiet and instability within the borders of the Empire.
However in spite of inflation, overtaxing and blackmailing bureaucracy the people of Israel in their country managed to continue their recovery due to the failed uprising in the century passed.
The author-editor of these biographies remains anonymous. Although one may presume he had been a fifth century Roman of the senatorial circles. The author-editor did not pretend to be a professional biography writer. Nevertheless, it is clear that he had been a man of letters who made great efforts to provide a vivid and reliable account of those stormy days, the last generations of pagan Rome.
