Festus

Festus (died 3 January 380) was a Late Roman historian. His name appears in some manuscripts as Rufius Festus, Rufus Festus, Sextus Rufus or Sextus Festus, but they appear to be corruptions. He is mainly known as the author of an epitome titled Breviarium rerum gestarum populi Romani ("Summary of the accomplishments of the Romans"), written around AD 370 and commissioned by the Eastern emperor Valens in preparation for his war against Persia. The Breviarium covers the entire history of the Roman state from the foundation of the city. The book consists of 30 chapters treating Roman events in a terse overview, mainly focused on military and political conflicts. It is estimated to be a work of very low quality.
