Use of the golden ratio

Image of a human body in a pentagram from Heinrich Cornelius Agrippa's Libri tres de occulta Philosophia. If the inner circle were the circumference of the building, the ground level would be at the base of the pentagram (at the figure's feet).^[4]

The extent that the circle is embedded in the ground was designed around the golden ratio.^[5]
