The Neolithic-Chalcolithic amalgam which seems to have been round about 2000 B.C. continued upto about the middle of the ﬁrst millennium B.C. It was then overlapped by the Megalithic culture inhabited by the megaliths builder. They are known not from their actual settlement which is rare but from their graves, these are called megaliths because they were encircled by big pieces of stones. About the beginning of the Christian era the Megalith culture in South India was overlapped by what has been called ‘Andhra culture’ on account of the occurrence of Andhra coins. This is the time when south India had a large volume of trade with Roman world. Again the culture and economic contacts between the north and the south paved the way for the introduction of material culture brought from the north to the Deep South by traders, conquerors, Jainas, Buddhist and some Brahaman missionaries. The Vindhya Range was recognized as the southern limit of the Aryan land. Manu states distinctly that the country between the Himalayas and the Vindhyas and between the eastern and western oceans comprised Aryavarta, the abode of the Aryans.
