The term ‘Ida’ enters the depth-psychology corpus along two principal axes that rarely intersect but share a common quality of numinous threshold. The first and most densely attested is geographical-mythological: Mount Ida in Crete and the Troad functions in the ancient sources—Rohde, Kerényi, Harrison, Homer—as a locus of divine manifestation, initiation, and cosmic erotic encounter. Rohde documents the Idaean cave as a site of chthonic Zeus worship and incubatory practice; Harrison traces the competition between Ida and Dikte as rival birth-sites of Zeus, exposing the political theology embedded in local cult. For Kerényi, Ida is the landscape in which Anchises pastors his cattle and Aphrodite descends, activating a mythologem of divine desire meeting mortal beauty. In the Iliadic tradition, preserved by Lattimore and the Homer 2023 translation, Ida is the vantage point of Zeus and the site where Sleep perches while Hera enacts her seduction—making it the mountain of divine surveillance, erotic cunning, and momentary unconsciousness of the ruling will. The second, more esoteric axis is Hillman’s alignment of ‘ida’ with the white current of kundalini yoga, paired against the red pingala, connecting it to the albedo stage in alchemical psychology. Strassman’s DMT volunteer named Ida supplies a marginal but humanly concrete instance. Greene’s index entry links Ida as both mount and mythic figure (Idas) within fate’s genealogy.
