" Take the figure of a man, with a raised arm, 2.20 metres total height, and place the figure within the frame of two rectangles, placed one on top of the other, each with a height of 1.10 metres; place a third rectangle within this framework, in such a way that you will attain a positive result. The position of the right angle will help you to find the correct location for the third rectangle."

" I am convinced that, provided with this working frame, which is regulated by the figure of a man positioned within it, you will attain a series of measurements, which will demonstrate how the human form (with a raised arm) and the science of mathematics can be brought together …."
