Hilma af Klint (1862-1944) was a pioneer of art that turned away from visible reality…. via magictransistor:
By 1906, she had developed an abstract imagery. This was several years before Wassily Kandinsky (1866-1944), Piet Mondrian (1872-1944) and Kazimir Malevich (1878-1935), who are still regarded as the pioneers of abstract 20th-century art. Hilma af Klint assumed that there was a spiritual dimension to life and aimed at visualizing contexts beyond what the eye can see. When painting, she believed that she was in contact with a higher consciousness that spoke and conveyed messages through her. Like many of her contemporaries, she was influenced by spiritual movements, especially spiritualism, theosophy and later anthroposophy. Through her paintings, she sought to understand and communicate the various dimensions of human existence. -Dr. M. Bunyan

The narrative is made clear through the discarded, black-edged envelope lying on the floor and the letter in the husband’s hand. He has just received news of the death of someone close to him and his wife, the ‘companion of manhood,’ comforts him in his grief. She is a dutiful wife in every way, clearly able to run an efficient and comfortable home. The table is neatly laid for breakfast and there are fresh flowers in the vase on the mantlepiece. She is attractive and well groomed, but not frivolous in appearance. Her concern is solely for her husband’s welfare and well being.
