At the heart of much of Beuys's artistic output lies an interest in sources of heat and energy. This is demonstrated in his sculptural work and installations through the use of fat and felt as materials. In this painting, the artist depicts the sun and a pylon, two sources of both heat and power. Beuys often incorporated unusual materials alongside watercolour in his paintings. Here he has used iron chloride, a chemical which also represents warmth as it gives off heat during the chemical process of hydrolysis, a reaction caused by water.
