Post-Nicene

Coptic abbot of the White Monastery near Atripe (Sohag) in Upper Egypt for some eight decades, the most prolific writer in the Coptic language and arguably the most important figure of native Egyptian Christianity in late antiquity. He authored a vast corpus of sermons, letters, and rules (the Canons), reformed cenobitic discipline beyond the Pachomian model, attacked surviving paganism in the Thebaid, and accompanied Cyril of Alexandria to the Council of Ephesus in 431. Largely absent from Greek and Latin patrologies, his Coptic Sahidic corpus is now central to the study of late-antique monasticism.

Roman Christian senator, philosopher, and theologian. Wrote the Consolation of Philosophy in prison and the theological Opuscula Sacra (Tractates) defending Chalcedonian Christology and Trinitarian doctrine. Executed under Theodoric. Bridges classical philosophy and medieval scholasticism.

Founder of Western monasticism. Established Monte Cassino c. 529 and authored the Rule of St Benedict, which became the foundational rule for Western cenobitic life. Known almost entirely through Gregory the Great's Dialogues Book 2.

Anonymous late 5th/early 6th-century Syrian Christian Neoplatonist who wrote under the pseudonym of Dionysius the Areopagite (Acts 17:34). Author of the Corpus Areopagiticum: Divine Names, Mystical Theology, Celestial Hierarchy, Ecclesiastical Hierarchy, and Letters. Hugely influential on later mystical and scholastic theology. NOT Paul's Athenian convert; identity disputed.
