“Circles in a Circle” (1923) is a compact and closed composition. Kandinsky began a thoughtful study of the circle as an artistic unit starting from this painting. In his letter to Galka Scheyer he wrote, “it is the first picture of mine to bring the theme of circles to the foreground.” The outer black circle, as if the second frame for a picture, encourages us to focus on the interaction between the inside circles, and two intersecting diagonal stripes enhance the effect, adding a perspective to the composition.
