Pseudo-Dionysius the Areopagite
ancientChristian NeoplatonismPseudo-Dionysius the Areopagite is the pseudonym of an unknown Christian theologian writing around 500 CE who falsely identified himself as the Dionysius converted by Paul in Athens (Acts 17:34). Drawing heavily on the Neoplatonism of Proclus, the author synthesized Greek philosophical categories with Christian theology to produce foundational texts on divine names, celestial hierarchy, and mystical union. The Dionysian corpus became one of the most influential bodies of theological writing in both Eastern and Western Christianity throughout the medieval period.
