This document discusses the origins and development of abstractionism in art. It traces the evolution of abstraction through movements like Impressionism, Post-Impressionism, Fauvism and Cubism that reduced representations of reality. Abstractionism was influenced by factors like nature, emotion, music, war and philosophy. It aimed to minimize representational meaning and reduce elements to basics like color and shape. The document examines geometric and non-geometric abstraction, focusing on pioneers like Kandinsky, Mondrian and O'Keeffe whose works emphasized elements like color, form and organic or geometric shapes. Examples of key works by each artist are provided.
