Leonardo was the foremost genius of the Italian Renaissance, and perhaps the most versatile genius that ever lived. He explored all the fields of human knowledge that were available in his time, inserting his superb intellect into every realm where graphic representation is used - including painting, sculpture, architecture, and engineering. His uncanny power of observation is revealed in his mastery of the art of drawing. He possessed an exceptional grasp of anatomy, astronomy, botany, and music. He designed and constructed numerous machines and drew plans for hundreds of inventions, including a flying machine and a parachute. His greatness was recognized by his contemporaries, and no generation since his time has failed to pay tribute to him. Pre-eminently a painter, Leonardo’s “Mona Lisa” and “The Last Supper” rank among the most popular works ever painted.
