SEXTUS AURELIUS VICTOR seems to have written his ‘Liber de Caesaribus’ (Book on the Emperors), a brief history of the Roman Empire, in 360–61. A contemporary of Victor, Ammianus Marcellinus, reports that, in 361, the emperor Julian:
“... returned to Naissus [Niš in Serbia] (a well-supplied town), from which he might without hindrance attend to everything that would contribute to his advantage. There he made Victor, the writer of history, whom he had seen at Sirmium and had bidden to come from there, consular governor of Pannonia Secunda, and honoured him with a statue in bronze, a man who was a model of temperance, and long afterwards prefect of the City [of Rome].”
Ammianus Marcellinus ‘Res Gestae’ Book XXI Chapter 10 (translation by John C. Rolfe)
The ‘EPITOME DE CAESARIBUS’ declares itself to be “abbreviated from the books of Sextus Aurelius Victor” (see above). The ‘Epitome’, however, includes material not found in the ‘Liber de Caesaribus’. It also extends some thirty-five years beyond Victor's book – the final sentence mentions the burial of Theodosius I, which occurred on 8th November 395. In the past, the ‘Epitome’ has been attributed to Aurelius Victor himself, but it is now well established that it was composed by another, unknown, author (sometimes referred to as Pseudo-Aurelius Victor).
As a result of reforms initiated by Diocletian (ruled 284–305), Pannonia had been divided into four. Pannonia Secunda was the south-eastern province, with Sirmium (now Sremska Mitrovica, Serbia) as its capital.
