Anima Mundi, Latin for "world's soul", is an ancient concept describing the intrinsic microcosmic and macrocosmic connections between all living things. Presented by Plato in ancient Greece, adopted by Neoplatonic philosophers, and by Hellenistic stoic Zeno, the Anima Mundi was viewed as the universe's sole vital force. In this painting the world's soul is shown as two bilaterally symmetrical orange equilateral triangles. The top triangle can be thought of as the feminine principle and the bottom, the male. Since they are paired point-to-point, they represent sexual union and the principle of harmony.
