EARLY SIXTH CENTURY. Rhetor and philosopher, not to be confused with the tenth-century bishop of Tricca in Thessaly with the same name. An adherent and contemporary of Severus* of Antioch, Oecumenius wrote the oldest extant Greek commentary on the Apocalypse, discovered early in the twentieth century. The work in twelve parts approached the biblical text historically. A commentary on the same book by Archbishop Andrew of Caesarea, written sometime between 563 and 614, referred to Oecumenius's work repeatedly. Other writings attributed to him came from different pens, including a commentary on Acts and expositions of the General and Pauline epistles, as well as a commentary on the Apocalypse edited by Donatus of Verona in 1532.
