LEGENDS OF LEMURIA: The term Kumari Kandam first appeared in the 15th century Kanda Puranam, the Tamil version of the Skanda Puranam. Yet, stories about an ancient land submerged by the Indian Ocean have been recorded in many earlier Tamil literary works. According to these accounts, there was a portion of land that was once ruled by the Pandiyan kings and was swallowed by the sea.
Most people are familiar with the story of Atlantis, the legendary sunken city as described by the ancient Greek philosopher Plato.
