Ancestor worship occupies a liminal but consequential position within the depth-psychology corpus, appearing at the intersection of soul-belief, ritual obligation, hero cult, and the psychic life of the family. Erwin Rohde’s foundational philological work establishes the Greek parameters most thoroughly: ancestor cult is the substratum from which hero worship evolves, sustained through precise funerary ritual — libations, sacrifice, the funeral feast — and institutionalized through adoption, inheritance, and testamentary provision. For Rohde, the cult of souls is not primitive superstition but the living architecture of Greek social and religious order. Gregory Nagy builds on this foundation by arguing that hero cult represents the polis-level transformation of ancestral worship, a distinction that carries Panhellenic implications for understanding Homeric epic. Hillman complicates the picture by diagnosing modernity’s collapse of ancestor into parent: where indigenous cultures maintained non-biological, spiritually qualified ancestors, Western biogenetics has reduced ancestry to chromosomal connection, leaving the psyche without genuine guardian figures. Joseph Campbell surveys ancestor-related mortuary rites cross-culturally, attending to the dangerous ghost, the appeased spirit, and the competitively consecrated sacrificial animal. Daoist scholarship through Livia Kohn documents systematic liturgical programs for liberating ancestral souls from perdition — a salvific extension of the basic structure Rohde identified. Across all traditions the corpus insists that right relationship to the ancestor is a psychological and not merely ceremonial necessity.
