South Australian artist Dorrit Black studied in Europe between 1927 and 1929 where she was immersed in modern art and learned about the golden mean from Cubist artist André Lhote. This mathematical formula was popular among modern artists and defines the recurring relationship and proportions of two forms, usually rectangles. Using this formula artists could create a grid upon which they could develop aesthetically pleasing compositions. In House-roofs and flowers, Black has used the golden mean to balance the composition and place objects at points most appealing to the eye.
