The Latin word æon means forever. It is derived from the Greek word αίών.

Temporal æon

This means the same thing as the word eon: an eternal frame of time, eternity.

Quantitatively, eon refers to a period of time of 1,000,000,000 years. However, geologists refer to the period in which animals evolved into abundance as the Phanerozoic Eon, which only lasts 545 million years, to the present day.

Platonic æons

The word æon was used by Plato to denote the eternal world of ideas, which he conceived was "behind" the perceived world, as demonstrated in his famous cave_allegory.

Gnostic æons

In many Gnostic systems, the various emanations of the God, who is also known by such names as the One, the Monad, Aiwn teleos (The Perfect Æon), Bythos, Proarkh (Before the Beginning), H'Arkh (The Beginning), are called æons. This first being is also an æon and has an inner being within itself, known as Ennoea (Thought), Charis (Grace), or Sige (Silence). The split perfect being conceives the second æon, Nus (Mind), within itself. Along with the male Nus comes the female æon Veritas (Truth)

The æons often came in male/female pairs called syzygies, and were frequently numerous (20-30). Two of the most commonly listed æons were Jesus and Sophia. The æons constitute the pleroma, the "region of light". The lowest regions of the pleroma are closest to the darkness; i.e. the physical world.

When an æon named Sophia emanates without her partner æon, the result is the Demiurge (or Ialdaboth), a creature that should never have come into existence. This creature does not belong to the pleroma, and the One emanates two savior æons, Christ and the Holy Spirit to save man from the Demiurge. Christ then took the form of the man, Jesus, in order to be able to teach man how to achieve gnosis; i.e. return to the pleroma.

Valentinian æons

According to Tertullian's Against the Valentinians (Latin: Adversus Valentinianos) chapter VII and VIII (and we only know the details of this system from its opponents), the Gnostic Valentinius had 30 different æons which emanate each other in sequence. The first 8 of these (corresponding to generations one through four below) is referred to as the Ogdoad.

• First generation
  • Bythos (the One) and Sige (Silence, Charis, Ennoea etc)
• Second generation
  • Nous (Nus, Mind) and Aletheia (Veritas, Truth)
• Third generation, emanated from Nous and Aletheia
  • Sermo (the Word) and Vita (the Life)
• Fourth generation, emanated from Sermo and Vita
  • Anthropos (Homo, Man) and Ecclesia (Church)
• Fifth generation
  • Emanated from Sermo and Vita:
    • Bythios (Profound) and Mixis (Mixture)
    • Ageratos (Never old) and Henosis (Union)
    • Autophyes (Essential nature) and Hedone (Pleasure)
    • Acinetos (Immovable) and Syncrasis (Commixture)
    • Monogenes (Only-begotten) and Macaria (Happiness)
  • Emanated from Anthropos and Ecclesia
    • Paracletus (Comforter) and Pistis (Faith)
    • Patricas (Paternal) and Elpis (Hope)
    • Metricos (Maternal) and Agape (Love)
    • Ainos (Praise) and Synesis (Intelligence)
    • Ecclesiasticus (Son of Ecclesia) and Macariotes (Blessedness)
    • Theletus (Perfect) and Sophia (Wisdom)

Ptolemaic and colorbasal æons

According to St. Irenaeus Against heresies (Latin: Adversus Haereses) also known as The Detection and Overthrow of Falsely So-Called Gnosis book 1, chapter 12, the followers of the Gnostics Ptolemy and Colorbasus had æons which differ from those of Valentinius. Logos is created when Anthropos learn to speak. The first four are called the Tetrad and the eight are called the Ogdoad.

• First generation
  • Bythos (the One) and Sige (Silence, Charis, Ennoea etc)
• Second generation (conceived by the One):
  • Ennoae (Thought) and Thelesis (Will)
• Third generation, emanated from Ennoae and Thelesis:
  • Nous (or Monogenes) and Aletheia
• Fourth generation, emanated from Nous and Aletheia:
  • Anthropos (Homo, Man) and Ecclesia (Church)
• Fifth generation, emanated from Anthropos and Ecclesia:
  • Logos and Zoe
• Sixth generation:
  • Emanated from Logos and Zoe:
    • Bythius and Mixis
    • Ageratos and Henosis
    • Autophyes and Hedone
    • Acinetos and Syncrasis
    • Monogenes and Macaria
  • Emanated from Anthropos and Ecclesia:
    • Paracletus and Pistis
    • Patricos and Elpis
    • Metricos and Agape
    • Ainos and Synesis
    • Ecclesiasticus and Macariotes
    • Theletos and Sophia

The order of Anthropos and Ecclesia versus Logos and Zoe are somewhat debated, different sources give different accounts. Logos and Zoe are unique to this system as compared to the previous and may be an evolved version of the first, totalling 32 æons, but it is not clear if the first two were actually regarded æons.

In the role-playing video game Final Fantasy X, an aeon is a creature that can be summoned by certain player characters and enemies. Aeons roughly equate to Guardian Forces (GFs) from earlier Final Fantasy games.

AEON is also a Japanese company chain (the asian department store giant, Jusco, is AEON's subsidary).
