What makes Leonardo da Vinci famous?

His paintings, his inventions and his scientific studies.

He owned unlimited talent as painter, mathematician, sculptor, architect, physicist, engineer, botanist and musician, but it was his skills in military engineering that first drew the attention of Ludovico Sforza, the Duke of Milan, for his incredible creative genius. While The Mona Lisa is his most impressive work, it was a clay sculpture of a great horse for an equestrian statue that was never finished in bronze, that has highlighted him for the first time as a great artist.
