Leonard da Vinci had incredible powers of observation, he saw the world around him like no one else. So many diverse areas occupied Leonardo's mind: painting, sculpture, anatomy, flight, architecture, water and air dynamics, war machines, nature and anything else that happened to catch his eye. Leonardo's interests and areas of study varied so greatly many of his works never saw completion. During his time in the service of the Duke of Milan he only finished about six works in 17 years.

Through this great man's sketches we get a window into one of man kind's greatest minds.
