Location: Neolithic Settlement of Dispilio, Greece. Discovered in 1993, the Dispilio Tablet is an ancient wooden tablet, etched with intricate symbols. Its symbols have yet to be deciphered, leaving its true purpose shrouded in mystery. Were these marks part of a record-keeping system? A symbolic ritual? Or could they represent one of the earliest known forms of written language? Unfortunately, after being unearthed, the wooden tablet began to deteriorate due to exposure to air.
