Enneads
The Enneads (Greek: Ἐννεάδες), fully The Six Enneads, is the collection of writings of the philosopher Plotinus, edited and compiled by his student Porphyry (c. AD 270). Plotinus was a student of Ammonius Saccas, and together they were founders of Neoplatonism. His work, through Augustine of Hippo, the Cappadocian Fathers, Pseudo-Dionysius the Areopagite and several subsequent Christian and Muslim thinkers, has greatly influenced Western and Near-Eastern thought.
