Pollution, as miasma, constitutes one of the most revealing fault-lines in the depth-psychological reading of Greek religious experience. The corpus traces a trajectory from the Homeric world, where pollution is essentially physical dirt that renders a man unacceptable to the gods without raising questions of moral responsibility, through the elaborate fifth-century system in which pollution becomes a contagious, quasi-metaphysical force that radiates from the killer into his community regardless of intention. Adkins supplies the most sustained analysis, arguing that this non-moral character of pollution—its indifference to motive, its automatic transmission, its remedy in ritual rather than repentance—reveals an archaic moral framework in which results rather than intentions govern evaluation. Dodds sharpens this into a formal distinction: pollution is the automatic consequence of an act operating like a pathogen, whereas sin presupposes an internalised conscience. Otto insists that archaic thought never severs the corporeal from the psychic, so that pollution corrupts the whole man, not merely his physical state. Rohde grounds pollution in the anger of the unavenged dead and the proximity of underworld spirits. Padel extends the logic into the tragic body, where illness, erotic obsession, and pollution form an interlocking field of dangerous intrusion. Together these voices make pollution a central index of how conscience, causality, and communal identity were structured in antiquity.
