de Divina Proportione (on the Divine Proportion): Facsimile (in Black and White) of the Original Version of 1509, Pacioli Luca, Da Vinci Leonardo

Even the layout of this book, which we may find somehow surprising today, Pacioli and da Vinci drafted it on a geometrical grid with respect to the divine proportion. De Divina proportione also is one of the most remarkable illustrated books published in the sixteenth century. Based on the writings of Plato, Euclid, and Vitruvius, and arguing his thesis by means of exegesis and the generous use of evocative illustration, Pacioli claims that this proportional element is shared by a variety of solid bodies, from human anatomy to architectural forms and even to the composition of the letters design in the Roman alphabet.
Today we dont know how many copies of De Divina Proportione were printed in Venice by printer Paganinus de Paganinus. Two surviving copies only exist, one at the Biblioteca Ambrosiana in Milan, and the second at the Biblioth que de Gen ve in Geneva, Switzerland.
For the intersection of art and science and the active engagement of the pre-eminent genius of the period, Leonardo da Vinci, this is one of the most iconic works of the Italian Renaissance. The clarity of both the written material and Leonardos diagrams gave the book a popularity beyond mathematical circles. It has since then been reprinted several times and translated in many languages.
