Define formalism what is it not influenced byexplain the difference between iconography and iconology

Formalism describes the critical position that the most important aspect of a work of art is its form – the way it is made and its purely visual aspects – rather than its narrative content or its relationship to the visible world.

Iconography refers to meaning of the symbols and images in art. Iconology is the study of imagery in terms of broader cultural and artistic content in art.
