Quadrature of the Lune
I decided to talk about Leonardo de Vinci in this blog because his art is amazing, and most of his sketches were influenced by mathematical ideas. Some of his sketches were influenced by the Quadrature of the Lune. In the context of Leonardo da Vinci, the lunes are interesting because Leonardo often used them in his designs of ornaments, and in the failed (of course) mathematical attempts of quadrature of the circle. R epresented below is one of his numerous designs related to a combination of polygons and circles in the "modern". The image below is known as Leonardo's claw.
