The title of the book refers to the Golden Ratio. What does it mean? Humans have been aware of the Golden Ratio for at least years. It is found in the patterns of nature. Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties. But the fascination with the Golden Ratio is not confined just to mathematicians.

Luca Pacioli was an Italian mathematician and friend of Leonardo da Vinci. P32 Although not stated explicitly, it is generally believed that Leonardo da Vinci did the illustrations for this book. Pacioli taught da Vinci mathematics and the two became close friends.

Pedretti, p. The book contains geometric studies of capital letters, including M, which was the iconic logo of the Metropolitan Museum of Art in New York from to There are 59 illustrations of polyhedra; some of which are solid, and some, like the one below, which are skeletal, making it easier to see edges and vertices. The publication actually contains 3 works which were completed in The first is Divina Proportione ; the second contains geometry related to architecture, including the golden ratio; and the third is an Italian translation of a work by Italian artist Piero della Francesca.

Mathematical Treasure: Luca Pacioli’s Divina Proportione

Franciscan friar and mathematician Luca Pacioli wrote several books on mathematics and geometry. Among them, in , Pacioli conceived De Divina Proportione , a treatise in vulgar on mathematical proportions applied to geometry and art with a specific focus on architecture and the human figure. The work was finally published in featuring illustrations by Leonardo da Vinci. Among other topics, De Divina Proportione also deals with the understanding of the composition of the letters of the alphabet with precise xylographic printings depicting their geometric constructions. All the letters are exclusively composed through straight lines and curves.

The Ambrosiana manuscript is a codex on parchment with folios in elegant humanistic script, and bears the date 14 December It was donated to the library in by Marquis Galeazzo Arconati, along with other Leonardo manuscripts including the renowned Codex Atlanticus. Each drawing becomes a true watercolour painting. The solid is shown, in compliance with the laws of gravity, hanging from a scroll, which identifies it by its Latin title in other words specifies which solid it is and what its characteristics are. We begin with the sphere and end with the amazing polyhedron with seventy-two faces, passing through all the possible and imaginable variations on the way. The exhibition shows a series of autograph documents of prominent women kept in the Ambrosiana.
