Also, in1509 ,Leonardo da Vinci created a wind-uplion as a greeting forLouis XII inItaly . Wind-up toys were at first for onlyroyalty , and were much more elaborate, with a very complex system of gears and springs.René Descartes also created a life-sized wind-uphuman girl to prove a theory that all animals were very complex machines. However, as legend goes, the mechanical girl was thrown overboard after a man was frightened by it.After the much larger, elaborate wind-up machine art declined in interest, wind-up toys were created very cheaply and in very large numbers by the 1800s. Wind-up machines then became known as wind-up toys, and were designed in all different forms to move around.
