John Bertram Peterson, Catholic Encyclopedia (1913)
“ There is always the primitive all-perfect Æon, the fountain-head of divinity, and a co-eternal companion Æon. From these emanate a second pair who, in turn, engender others, generally in pairs, or in groups of pairs, in keeping with the Egyptian idea of divine couples. One of these inferior Æons, desiring to know the unknowable, to penetrate the secrets of the primal Æon, brings disorder into the Æon-world, is exiled, and brings forth a very imperfect Æon, who, being unworthy of a place in the Pleroma, brings the divine spark to the nether world. ”
