EDAKKAL CAVES, WAYANAD, KERALA, INDIA
The caves were discovered by Fred Fawcett, a British police official of the erstwhile Malabar state in 1890 who immediately recognised their anthropological and historical importance. The petroglyphs inside the cave are of at least three types. The oldest may date back to over 8,000 years. Evidences suggest that the Edakkal caves were inhabited several times at different points in history.The caves contain drawings that range over periods from as early as 8000 BC to 1000 BC. The youngest group of paintings have been in the news for a possible connection to the Indus Valley Civilization. Dr. M. R. Raghava Varrier of Kerala State Archaeological Department recently discovered a Malayalam word "SREE VAZHUM" in the caves made the origin of language as early as first century AD.
