Within the depth-psychology and ecclesiastical-history corpus, Photius — ninth-century Patriarch of Constantinople, polymath, and central figure in the rupture between Rome and Byzantium — appears almost exclusively through the exhaustive revisionist scholarship of Francis Dvornik. Dvornik’s monumental 1948 work dismantles centuries of accumulated legend, arguing that the ‘Photian Schism’ was less a principled theological rupture than a product of Byzantine court politics, Roman curial overreach, and the systematic distortion of sources by the anti-Photian Collection. The corpus treats Photius simultaneously as historical actor, contested symbol, and hermeneutic problem: his canonical election, exile, rehabilitation, encyclical challenge to Rome, and ultimate reconciliation with both Basil I and the papacy become lenses through which questions of ecclesiastical authority, conciliar legitimacy, and the manufacture of legend are examined. Key tensions include the opposition between Photius as schismatic villain (the Western Catholic tradition from Nicholas I through Baronius) and Photius as vindicated patriarch (the Greek Orthodox tradition); between the ‘historical’ Photius recoverable from primary sources and the ‘legendary’ Photius shaped by dynastic propaganda and polemical need. The corpus reveals how his name became, over centuries, a symbol whose content shifted with each party that invoked it.
