The earliest surviving yo-yo dates to 500 BCE and was made using turtle skin disks. A Greek vase from this period shows a boy playing yo-yo.[3][4] Greek records from the period describe toys made out of wood, metal, or painted terra cotta (clay). The terra cotta disks were used to ceremonially offer the toys of youth to certain gods when a child came of age—discs of other materials were used for actual play. The idea that Philippine historical records indicate that 16th century hunters hiding in trees used a rock tied to a cord up to 20 feet in length to throw at wild animals beneath them—the cord enabling retrieval of the rock after missed attempts—has no basis in fact. Conventional wisdom surmises that this was the basis of the yo-yo, but Valerie Oliver, one yo-yo enthusiast who fails to provide any factual basis for her contention, claims that the yo-yo traveled from China to Greece and to the Philippines.[5]
