Abstract
After a short presentation on the figure and work of Novatian to give context to the evidence, this article examines the sources on the episcopal consecration of Novatian as a rival to Cornelius, the bishop of Rome. We learn of this from Photius’ Bibliothecae codices 182 and 280, which preserves fragments of the lost works against the Novatians of Eulogius, Chalcedonian patriarch of Alexandria, which draw in turn on the lost Acta Nouatiani. This study proposes to identify Tibur (Tivoli) as the episcopal see of one of the three prelates who consecrated Novatian, thus allowing us to include in the episcopal succession of that Church two more names (one certain, the other fictitious, perhaps referring to one of Novatian’s entourage) for the middle of the third century. This is unique for an Italian see outside the city of Rome.
