This delightful introduction to the inventions of Leonardo da Vinci teaches young readers about the painstaking but rewarding art of design and discovery. George the sheep is happy living outside in his meadow except for one thing: when it rains, he shrinks to the size of a mouse; when the sun comes out he grows enormous. Befuddled, his owner Leon sets out to find a way to shelter George from the rain. A huge set of bat wings to dry his fur? A wheeled chariot to keep out the wet? Finally he alights on the perfect solution―a large umbrella. But when the wind plays havoc with this contraption Leon must put pencil to paper once again to come up with a solution. Through careful measuring, sketching, and a truly indefatigable spirit, Leon, like his fifteenth-century namesake, solves the kinds of problems that have challenged inventors throughout history. Cleverly invoking the mechanical genius of Leonardo da Vinci, this delightful children’s book explores the art of invention through illustrations and an entertaining story.
