Aeon (Gnosticism)

In Gnostic mythic cosmologies the Monad or Perfect Being (variously named Bythos, Proarkhe, Arkhe) issues forth a series of emanations. These emanations—Aeons—are generated by processes described differently in particular schools: for example, Valentinian systems arrange Aeons into male/female pairs (syzygies), Basilidian accounts use sonship terminology, and some narratives describe a 'split perfect being' whose internal conception produces Nous (Mind) as a second Aeon. Named hypostases such as Bythos, Aion teleos, Proarkhe, Arkhe, Nous, Sophia, and Christos figure in these genealogies and together constitute the Pleroma, the fullness of divine reality (sources: Wikipedia Aeon; Gnosticism explanatory materials).

Primary sources and overviews treat Aeons as metaphysical hypostases or personified divine principles rather than as consistently depicted sensory-bodied beings. When named (e.g., Nous, Sophia) they function as persons or attributes within the Pleroma, but the supplied texts do not provide uniform physical descriptions or corporeal iconography for Aeons; they are principally conceptual/divine entities inhabiting the realm of light (sources: Wikipedia Aeon; Gnosticism summaries).

Aeons perform ontological and mediatory functions: they emanate from the supreme source, generate subsequent divine hypostases, and together constitute and structure the Pleroma. In mythic accounts an Aeon may be the originator of another Aeon (the 'split perfect being' conceiving Nous) or form part of ordered hierarchies that explain how divinity unfolds. Specific relations, numbers, and roles of Aeons differ by system—for instance, Valentinian syzygies (male/female pairs) or Basilidian sonship language—so detailed capacities and interactions are system-dependent (sources: Wikipedia Aeon; Gnosticism explanatory materials).
