idol, an object, frequently an image, which is worshiped as a deity. Idols are usually found in human or animal form and may be treated as though alive; they are fed, bathed, anointed, crowned, and sometimes even provided with a consort. Christians and Jews extend the term to include any deity other than their own; theologically, however, idol worship is generally applied to the adoration of what is seen and tangible as opposed to the worship of an unseen spiritual being.
