What may be the world’s oldest map has been discovered engraved on a 14,000 –year-old slab of rock in a cave in the Spanish Pyrenees. The cave in which the map was found is steeped in legend and was traditionally thought to be the home of mythological bird-footed nymphs. The questions which have puzzled researchers are what they were used for and why prehistoric hunter gatherers living in caves would need maps?
