Indian art has been the product of Indian culture as the Greek art has been the product of Greek culture or the Roman art has been the product of Rom… - Swaraj Prakash Gupta

What is, however, much more significant to note is that here we have the longest sequence of cultures, without any break whatsoever, upto the Early Indus-Sarasvati. In other words, this sequence does not allow any outside agency to come and effect changes in the step-by-step growth of culture. If this is realised clearly, it will not leave any scope for doubt in the indigenous of the origin and growth of the Indus-Sarasvati Civilization; at Mehrgarh from around 4000 B.c. we start getting all those characistic features which went directly into the make-up of the Early Indus sarasvati Civilization.

The Indus-Sarasvati Civilization is found extending for more than 1600 km from north to south and equally from east to west, covering an area of about 2.5 million sq. km and more. The northernmost site known to us so far is Manda, located on the River Beas near Jammu; the southernmost site is Bhagatrav on the RiverTapti in Gujarat; the easternmost site is Bhorgarh in east Delhi and Alamgirpur in district Meerut; and the westernmost site is Sutkagendor, located on the ancient shore of the Arabian Sea, near the eastern border of Iran. The Indus-Sarasvati Civilization was, therefore, around four times more in area coverage than any contemporary civilization, including the Egyptian and the Mesopotamian.

All this clearly shows that, in the process of the formation of the Indus-Sarasvati Civilization, which was typically a lowland cultural phenomenon, not one but several regions were directly or indirectly involved, as has been pointed out by Mughal. The usual American perception (of scholars like Possehl) that the highland Baluchi cultures, such as the Quetta culture with roots in Iranian Neolithic cultures of the Zagros mountains, and the Iranian Bronze Age cultures were primarily responsible for the birth and early growth of the Indus- Sarasvati Civilization, therefore, requires serious reconsideration since the pre-4000 BC cultures leading to the 4000 BC settlements are now locally available in Punjab, Haryana, Rajasthan, and Gujarat, particularly at Harappa, where a four-metre deposit of handmade black painted red ware with mud-brick houses was found in early 1996.
