Big breakthroughs once again: Artemis, Celtic Artio, Illyrian/Thracian Ara of Ara Zea all related to PIE *hrktos, "bear", from a root meaning that I describe in this paper. I've also found the correct etymology of Kotys/Kottyto: it's from a root meaning "to prick, to goad", not from "to grasp". I may also have partially determined the etymology of Hera. Also I have found the explanation of why Artemis/Artio/Ara Zea are goddeses of rebirth and resurrection, not just of childbirth.
