An illustration from De Divina Proportione, a mathematical treatise by the Franciscan friar Luca Pacioli (1445-1517). The Italian text is followed by sixty polyhedra, drawn filled or empty, and influenced by Leonardo da Vinci. Of the three copies written during the author’s lifetime, only two remain. The copy held by the Bibliothèque de Genève is the presentation copy of the Duke of Milan, Ludovico Sforza, whose coat of arms and motto adorn the manuscript.
