Enneads

The Six Enneads, sometimes abbreviated to The Enneads or Enneads (Greek: Ἐννεάδες), is the collection of writings of Plotinus, edited and compiled by his student Porphyry (c. 270 AD). Plotinus was a student of Ammonius Saccas and 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.

Organization and content

Porphyry edited the writings of Plotinus in fifty-four treatises, which vary greatly in length and number of chapters, mostly because he split original texts and joined others together to match this very number. Then, he proceeded to set the fifty-four treatises in groups of nine (Greek. ennea) or Enneads. He also collected The Enneads into three volumes. The first volume contained the first three Enneads (I, II, III), the second volume has the Fourth (IV) and the Fifth (V) Enneads, and the last volume was devoted to the remaining Enneads. After correcting and naming each treatise, Porphyry wrote a biography of his master, Life of Plotinus, intended to be an Introduction to the Enneads.
