The theme of bulls and horses was a favorite of Franz Marc, one of the most prominent masters of German expressionism and a member of “The Blue Rider” group in Munich. He deliberately refused to paint people, believing that animals are “more natural and pure.” With their help, he wanted to feel the “organic rhythm of all things, " to comprehend the spiritual side of the universe. The tempera painting Red Bullock from the Moscow collection gives an impression of the artistic style of Franz Marc through its crystal-clear transparency, clarity of forms, and inner energy of light.
