"These dates Mueller later insisted were minimum dates only, and latterly there has been a sort of tacit agreement... to date the composition of the Rigveda somewhere about 1400-1500 BC, but without any absolutely conclusive evidence."

"S. Piggott established the presence of a sophisticated type of vehicle with “one or two pairs of wheels with their axles... from the Rhine to the Indus by around 3000” (1992: 18)."

"In sum, however, the evidence from Baluchistan and from Sind and the Punjab is reasonably consistent in implying that at some period likely to have been before 1500 BCE (to use a convenient round figure), the long-established cultural traditions of North-Western India were rudely and ruthlessly interrupted by the arrival of a new people from the west. The burning of Baluchi villages and the equipment of the graves at Sahi Tump suggest that these new arrivals were predominantly conquerors who traveled light and adopted the pottery of the region in which they established themselves. In Sind, at Chanhudaro, a barbarian settlement appears [evidently the reference is to the Jhukar Culture] in the deserted ruins of the Harappan town, and here some local craftsmen may have remained to work for their alien masters, while the pottery suggests a resurgence of local, non-Harappan elements. At Mohenjo-daro, it seems clear that the civilization that had survived so long was already effete and on the wane when the raiders came, and at Harappa we know from the evidence of the rebuilding of the Citadel walls that the inhabitants were on the defensive in the last days of the city, though, these precautionary measures did not suffice to keep away the intruders, wherever they came from, who afterwards settled on the ruins and buried their dead in Cemetery H for generations."

"The method has its dangers—the great Sanskrit scholar A. B. Keith once remarked that by taking the linguistic evidence too literally, one could conclude that the original Indo-European speakers knew butter, but not milk; snow and feet, but not rain and hands!"
