Facsimile Edition Description 2 Luca Pacioli ca. In his De Divina Proportione he brought together, for the first time in the vernacular, current thought on the divine nature of geometry. He also described the application of geometry to art and architecture imbuing these art forms with divine content. Working in Milan in close association with Leonardo da Vinci, Pacioli wrote a text that would have profound influence on science and art in the age of humanism.
Leonardo himself drew the geometrical illustrations for the manuscript. On the presentation page a miniature records the event. Ludovico Sforza, also known as Ludovico il Moro, is shown seated with four members of his court. He reaches out to accept the book proffered by its author. The Sforza arms decorate the lower section of the folio. The crisp beauty of the geometrical, skeletonic figures is breathtaking. The drawings stand as a landmark in the evolution of stereography as they are the first to show clearly the distinction between the front and the back of the three-dimensional solids.
When working at the court in Urbino, he wrote a text in which he explained double-entry accounting. This text earned Pacioli a pre-eminent position in the history of commerce.
He has been appropriately awarded the title "father of accounting" in the recent literature on business history. He taught Leonardo the intricacies of geometry and Leonardo informed Pacioli of the application of geometry to art and architecture. In his study of Divine proportion Pacioli first dealt with current thinking on theology, philosophy and music in the light of mathematics as expressed in the golden ratio golden section or golden mean.
Piero della Francesca and Pacioli had certainly exchanged ideas on geometry and art at the court in Urbino. The foundamental importance of the masterpiece The entire text of De Divina Proportione stands as a compendium of theological, theoretical and practical mathematical knowledge that would resonate in the world of Renaissance art and architecture.
The importance of this manuscript in the life and works of Pacioli is clear in the three extant portraits of this often underappreciated humanist.
The image in the presentation miniature was preceded by a portrait painted by his friend Piero della Francesca who cast Pacioli in about as St. Peter Martyr in The Montefeltro Altarpiece — a critical monument in the history of art.
Pacioli is shown standing behind a table on which are the instruments of geometry and a book, quite possibly his De Divina Proportione, in red leather binding. That this is a pictorial monument to his manuscript with its illustrations by Leonardo da Vinci, is suggested by pictorial representations of a transparent polyhedron rhombicuboctahedron suspended from the ceiling and an opaque dodecahedron sitting on top of the bound manuscript.
