Alchemy
The Greco-Roman tradition of Prima Materia, notably including 5th and 6th centuries Orphic cosmogony was merged with biblical notions (Tehom) in Christian belief and inherited by alchemy and Renaissance magic.
The cosmic egg of Orphism was taken as the raw material for the alchemical magnum opus in early Greek alchemy. The first stage of the process of producing the Lapis Philosophorum, i.e., nigredo, was identified with chaos. Because of association with the creation in Genesis, where "the Spirit of God moved upon the face of the waters" (Gen. 1:2), Chaos was further identified with the element Water.
