John Opsopaus, Ph.D.

With a Ph.D. in Computer Science and decades of independent scholarship in classical studies, he has devoted much of his career to recovering the philosophical and spiritual worldview of ancient Greece through the study of Platonism, Neoplatonism, Pythagoreanism, Orphism, and the Greek magical traditions. His work has become an important bridge between academic scholarship and contemporary practitioners seeking a deeper understanding of Hellenic spirituality and philosophy.

Opsopaus is best known for his translations and commentaries on the Greek Magical Papyri (PGM), one of the most significant surviving collections of ritual, devotional, and magical texts from the ancient Mediterranean world. His research places these writings within their broader historical and philosophical contexts, demonstrating how ancient ritual practice was deeply intertwined with Platonic metaphysics, cosmology, theology, and the lived religious traditions of the Hellenistic world.

Among his most influential works are The Oracles of Apollo, The Secret Texts of Hellenic Polytheism, The Pythagorean Tarot, and his extensive studies on Hellenic magic, divination, and Neoplatonic philosophy. His writings explore subjects including Greek cosmology, daimons, theurgy, sacred mathematics, astrology, dream incubation, ritual purification, and the philosophical foundations of ancient religion. Throughout his work, Opsopaus emphasizes that Greek spirituality was not merely a system of myth but a sophisticated philosophical tradition concerned with the cultivation of virtue, wisdom, and participation in the divine order of the cosmos.

In addition to his scholarly publications, Dr. Opsopaus has lectured internationally on ancient philosophy, Greek religion, Neoplatonism, theurgy, and esoteric traditions. His teaching is distinguished by its combination of historical precision, philosophical depth, and practical insight, making the often complex ideas of classical antiquity accessible to both scholars and modern practitioners.

Recognized as one of the foremost contemporary interpreters of Hellenic philosophy and spirituality, John Opsopaus continues to inspire students around the world through his careful scholarship and enduring commitment to preserving the intellectual and contemplative traditions of the ancient Greek world.
