Neoplatonist philosophy and theurgy

Porphyry

234 – 305

Porphyry of Tyre was a Syrian-born Neoplatonist philosopher and student of Plotinus, whose writings he edited and collected into the Enneads. He wrote extensively on philosophy, religion, and the occult sciences, and authored a polemical anti-Christian treatise, while his Isagoge shaped medieval logic for centuries. His works on theurgy, vegetarianism, and the soul were foundational to later Western esoteric currents.
