I have a great love of symbolism. The figure in the head is called the Vitruvian Man by Leonardo da Vinci. It has been said that the Vitruvian Man exemplifies the blend of art and science during the renaissance. The Vitruvian Man to me is a symbol of a healthy, balanced human being.
Placement of the Vitruvian Man in a head is a representative symbol that your brain is the control center of your whole body. What happens in the head translates to the rest of your entire body. Structure (cranium) governs function and the brain receives and delivers messages. When there is an imbalance at the top…..ie the command center, it is represented throughout the body.
