Ancient Handcrafted Spheres: Unraveling the Mystery
Ancient limestone spheroids found at the 'Ubeidiya prehistoric site in Israel, dating back 1.4 million years, were intentionally shaped to achieve a spherical form, according to archaeologists. The more the spheroids were worked, the rounder they became, indicating a deliberate goal of achieving perfect geometry. The purpose of these spheroids remains unknown, but their intentional production suggests a complex cognitive process and the earliest attempt at imposing symmetrical geometry on stone tools.
