In 1969, archaeologist BK Thapar excavated Kalibangan (Rajasthan, India). They dug out a settlement that dates back to the mature IVC phase (c. 2600 BC) along the banks of the now-extinct Sarasvati river.
But the archaeologist was shocked. He saw that the 4500-year-old houses had tiled floors. And the tiled floors were painted with a design. ‘This is exactly the design on the floor of my own house’- the startled archaeologist exclaimed. Such is the continuity of past and present in India!
