Some might notice our logo and wonder why we chose this design, where it comes from or what it means. It is a stylized version of Leonardo da Vinci's Vitruvian Man which was illustrated in approximately 1487.
The pen and ink drawing is named after Marcus Vitruvius Pollio, a Roman engineer who first noted the proportions and geometry of the human body, and which da Vinci quotes alongside his diagram.
The illustration shows a male figure in two superimposed positions with his arms and legs apart and simultaneously inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man.
Several of the proportions that da Vinci shows are:
•a palm is the width of four fingers
•a foot is the width of four palms
•a cubit is the width of six palms
•a man's height is four cubits (and thus 24 palms)
•the length of a man's outspread arms (arm span) is equal to his height
•the distance from the elbow to the tip of the hand is a quarter of a man's height
•the length of the hand is one-tenth of a man's height
•the length of a man's foot is one-sixth of his height
Chiropractic care emphasizes balance between lifestyle, environment, and health. This includes checking for proper proportions between various parts of the body, where imbalances could mean subluxations or joint misalignments. One can see why this would be a common symbol of the medical field, especially areas considered physical medicine, complementary and alternative medicine, or any other field with a holistic approach to health and wellness.
