Milan, Italy

Pacioli and da Vinci met each other and fostered a close connection through mathematical collaboration in this city. da Vinci was in the Court of Milan in 1494 when Pacioli’s Summa de arithmetica, geometria, proportioni et proportionalita was published. Since da Vinci bought a copy of this text as soon as it was published, it is reasonable to assume that da Vinci pushed for the invitation of Pacioli to the Court of Milan. During his stay in Milan, Pacioli shared living quarters with da Vinci at the Corte Vecchia. In later letters, Pacioli would look back on this time shared with da Vinci in Milan very fondly.

Leonardo Da Vinci Plans the Largest Equestrian Statue

In 1482, Leonardo Da Vinci was asked to create the largest equestrian statue in the world by Ludovico Sforza who would later be the Duke of Milan (National Geographic). By studying real horses, Leonardo created plans and a clay model around 1493. He planned to be able to cast the horse in only one process by putting molds between two ovens and filling them to cast the entire statue. In 1499, though, Milan was in war with France during the Second Italian War (also known as the Italian War of Louis XIII) and French troops invaded the city (History of War). The bronze that was going to be used for the horse statue was instead used for weapons for Milan; when Milan was eventually defeated by France, French archers destroyed the clay model (Da Vinci Science Center). With the model ruined and his supplies repurposed, Leonardo Da Vinci never tried to construct the horse again.

Collaboration between Pacioli and da Vinci

After arriving in Milan in 1496, Pacioli formed a very close connection with da Vinci in which he tutored da Vinci in mathematics. The two men had a deep friendship that transcended their mathematical endeavors; their notebooks include comments to one another like “Well Leonardo, you can do more of this on your own” and “learn the multiplication of roots from Maestro Luca." They also shared the task of providing entertainment to the Court of Milan; their entertainments included brainteasers, magic tricks, and riddles. Mathematically speaking, the duo shared a deep interest in geometric shapes. Pacioli successfully taught da Vinci the works of Euclid’s Elements and less successfully taught him arithmetic techniques like multiplying squares and square roots.  During this time, da Vinci created several sketches of polyhedra that would be featured in Pacioli’s publication De Divina Proportione. In 1499 the French invaded Milan and the pair was forced to flee the city, eventually settling in Florence (where they lived together).
