Targeted at grade-schoolers, this book from National Geographic provides a beautifully illustrated overview of the life and works of the famous Renaissance Man. The book includes numerous photos and reprints of Da Vinci's most famous works, and well as reproductions of some of his designs.
While he's most famous for The Mona Lisa and The Last Supper, Da Vinci, in fact, only completed a few paintings during his lifetime, magnificent though they may be. Da Vinci painted, sculpted, created sets for plays, and designed numerous machines for war.
The book is well-written, and is designed and laid out beautifully. The amazing imagery used in the book makes for a great way to introduce Leonardo and the Renaissance.
