A rock engraving, indicating clear remnants of Harappan culture, has been found in the Edakkal caves in neighbouring Wayanad district, linking the Indus Valley civilisation with South India.
"There had been indications of remnants akin to the Indus Valley civilisation in Karnataka and Tamil Nadu, but these new findings give credence to the fact that the Harappan civilisation had its presence in the region too and could trace the history of Kerala even beyond the Iron Age," historian M R Raghava Varier said.
The unique symbols integral to the Indus Valley culture traced in Harappa and Mohanjedaro region that stretched upto Pakistan, were found inside the caves during recent excavations by the State Archaeological Department.
Of the identified 429 signs, "a man with jar cup", a symbol unique to the Indus civilisation and other compound letters testified to remnants of the Harappan culture, spanning from 2300 BC to 1700 BC, in South India, Varier, who led the excavation at the caves told PTI.
The "man-with-the-jar" symbol, an integral remnant commonly traced in parts where the Indus Valley civilisation existed, has even more similarities than those traced in Karnataka and Tamil Nadu, he said.
