What is canon of proportion?

Canon of proportion is a set of mathematical rules developed by ancient Greek sculptors and architects to create harmonious and balanced designs in their artwork. The canon of proportion involves dividing the human body into a series of parts, each with a specific ratio to the others. For example, the height of the human body is divided into eight parts, each of which is equal to the length of the head. Similarly, the width of the shoulders is equal to two heads, and the distance from the top of the head to the bottom of the feet is equal to seven heads. These ratios were based on the belief that they created a pleasing and balanced form that was in harmony with the universe. The canon of proportion was used in sculpture, painting, and architecture, and its principles have been influential in art and design throughout history.
