Geometry of the golden section

Thanks to a simple rope on which they made a knot at every "cubit" cathedral builders drew their plans on the ground making wonderful figures to define and create the whole architecture and its decor according to ideal proportions.

Their constructions are beautiful and deeply moving.

By using a ruler and compasses only, to replace the rope, Robert Vincent reveals to us the secrets of those builders in the art of line drawing, as well as in the establishment of "divine proportions" thanks to the Golden Section.

Robert Vincent's drawings do not need any mathematical knowledge and sweep us away into a universe of emblematic figures, or into that of the Golden Section in human achievement, from the pyramid of Cheops to that of the Louvre, or from Le Corbusier, to the Marseille's Tarot, or the official soccer ball...

Thus he shows us the marvels of geometry and offers ancient designs that are still relevant for present day artists or crafstmen in all the fields where the creation of lines and shapes in harmonious proportions can be found. The author also shows us some geometric curiosities such as the duplication of a cube, mandalas, drawing trisections, the squaring of the circle or Leonardo Da Vinci's canon of proportion. He makes them all so easy for us!
