What is "enneads"

The Six Enneads, sometimes abbreviated to The Enneads or Enneads , 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.
