“At the end of the third millennium the strong flow from the Sarasvatī dried up... This [the drying up of the Sarasvatī towards the end of the third millennium] carries with it an interesting chronological implication: the composers of the Rgveda were in the Sarasvatī region prior to the drying up of the river and this would be closer to 2000 BC than it is to 1000 BC, somewhat earlier than most of the conventional chronologies for the presence of the Vedic Aryans in the Punjab.”
