Religious Art - all of these definitions have been used at one time or another to define religious art. The most common definition is that religious art is that which depicts biblical themes. Such art abounds, particularly that done in earlier centuries; but it is still prominent today.
The next suggestion-that art is what religious artists do-saw its highest expression in the Renaissance when the church employed great artists who experimented with themes not only from biblical settings but from classical mythology as well. Often in history, "religious art" was what the church officially declared to be religious art. The most extreme example of this style is to be recalled in the Inquisition of the sixteenth century and in iconoclastic excesses right up to the present time.
