Leonardo da Vinci: the genius who survived the political intrigues and wars of his time to produce many inventions, entertainments, and major works of art and became a legend of the Renaissance and Modernity. He overcame his disappointments and humiliation in Florence, the murder of his sponsor Gian Galeazzo Sforza the young duke of Milan, the negative effects of the French-Italian wars on his life and work, and the pressure to leave his beloved Italy and to live and die in France in the service of the French king Francois I.  The Melzi Chronicles and The Pacioli Code are reflections from pages of his secret notebooks and remembrances of his friends and acolytes and his festivities, inventions, paintings, and natural philosophies as an artist, scientist, and legend. The books reveal and reinterpret the hidden meanings behind many of the Master’s drawings and paintings; challenge the art historians and debunk the falsehoods, bad memes, and those long held misconceptions about the Maestro and his works.
