From Ancient Greek ἀρχαῖος (arkhaîos, “original, ancient”). Compare with Arche (/ˈɑːrki/; Ancient Greek: ἀρχή; “beginning”, “origin” or “source of action”) + Chaos (Ancient Greek: χάος, romanized: kháos), the void, the Absolute. In alchemy, archeus refers to the vital principle or force that presides over the growth and continuation of living beings; the anima mundi or malleable power of the alchemists and philosophers.
