One of the artist that I've read about avidly, is Paul Klee. Born in 1879, his was a brilliant career that incorporated Cubism, and the German alternative to Cubism - German Expressionism. Working with his friend Wassily Kandinsky, considered the father of Abstract art, as tutors at the Bauhaus. Much is written about both artists.
Today I wanted to draw reference to the wide ranging subject matter and sources, Klee incorporated in his inventions.
Phillip Larson wrote " His internal source books laid out Cubist frameworks, stratified color charts, calligraphic flourishes, children's drawings, proto-Surrealist doodles, toys and puppets, caricatures, tribal masks, minute zoological/biological specimens, architectural/theatrical perspectives, pictographs/hieroglyphs, and, of course, all keys to the German typewriter. To this day, no historian has secured the critical perimeters around the prodigious collector-progenitor."
His love for music, musical instruments and the theatre were also depicted in numerous drawings and paintings.
