Within the depth-psychology and comparative religion corpus, the olive tree functions as a remarkably dense symbolic nexus, drawing together theology, ritual, political mythology, and contemplative exegesis. Its most sustained treatment occurs in the context of Athena: for Harrison, Harvey, and Campbell, the olive is at once the Greek ‘Tree of Life,’ Athena’s signature gift to Athens, and an emblem of divine wisdom whose roots antedate Olympian religion and reach into the chthonic religion of the Great Goddess. Burkert, with characteristic anthropological precision, situates the sacred olive of the Pandroseion within the sacrificial crisis of the Panathenaic festival, reading the goat’s trespass and death as a ritual drama inseparable from the tree’s inviolability. Harrison extends the symbol further, tracing the Olympic victor’s olive crown to a probable lunar antecedent — the moon-goddess’s tree — and locating the olive’s earliest identity in the earth itself. A wholly distinct line of exegesis appears in the Philokalia, where two olive trees flanking Zechariah’s lampstand become allegories for the natural and spiritual laws, the Old and New Testaments, or the paired faculties of practical virtue and contemplative intellection. Onians contributes an archaic stratum, connecting olive oil to ambrosia and the divine substance of immortal life. Together these voices reveal a symbol whose meanings range from civic and political triumph to mystical epistemology.
