The Iconoclasts (those who rejected images) objected to icon veneration for several reasons, including the Old Testament prohibition against images in the Ten Commandments (Exodus 20:4) and the possibility of idolatry.

What was the reason for iconoclasm?

Iconoclasm is generally motivated by an interpretation of the Ten Commandments that declares the making and worshipping of images, or icons, of holy figures (such as Jesus Christ, the Virgin Mary, and saints) to be idolatry and therefore blasphemy.

What is iconoclasm and why is it significant?

Iconoclasm (from Greek: εἰκών, eikṓn, 'figure, icon' + κλάω, kláō, 'to break') is the social belief in the importance of the destruction of icons and other images or monuments, most frequently for religious or political reasons.
