- In religion, idols are man-made objects that are venerated for the spirit or daemon that they embody; Christians call their worship idolatry, the worship of hollow forms. The neutral term is cult image. Compare icon, fetish. The word entered Middle English in the 13th century from Old French idole adapted in Church Latin from the Greek eidolon ("appearance" extended in later usage to "mental image, apparition, phantom"). Greek eidos means "form"  as used by Plato.
