Scriptores Historiae Augustae
The enigmatic imperial biographies
b. c. late 4th century AD
The Historia Augusta is a collection of thirty biographies of Roman emperors from Hadrian to Carinus (117–284 AD), purportedly by six authors during the reigns of Diocletian and Constantine. Modern scholarship has established that it was written by a single anonymous author, probably in the late fourth century, who invented the six authorial personae.
The biographies vary enormously in reliability. Those covering the second century draw on genuine sources. Those covering the third century become progressively more fictional. Despite — or because of — its unreliability, the Historia Augusta is one of the most fascinating texts to survive from late antiquity, often our only narrative source for the chaotic third century.
