I've been reading this cool book about da Vinci.
About Leonardo da Vinci or simply Leonardo? What did you learn about him?
Leonardo da Vinci, he was a very interesting man. He was an architect, musician, engineer, scientist and inventor.
Thats exactly why he has been variously called the father of palaeontology, ichnology, and architecture. He is an inspiration! 
Yes, he's most known for painting the Mona Lisa. 
I have actually seen Mona Lisa, it has been described as "the best known, the most visited, the most written about art of all time!
