I think iconoclasm is interesting. It's been an issue for any monotheistic religion that wants to distinguish itself from paganism.

Crucifixion and Iconoclasts, Chludov Psalter, mid 9th century

This image is a page from a Medieval book of Christian parables, made on vellum. There is an illustration from a scene of the crucifixion, when people tormented Jesus on the cross by dabbing vinegar into his wounds. Below is an image of a iconoclast destroying an image of Jesus by painting over it. This work refers back to a Christian campaign during Byzantine era banning the use of icons and ordering their destruction. The psalter makes a harsh statement about iconoclasts by comparing them to Jesus’ tormentors.
