Common sense might suggest that here was a striking example of a refutable hypothesis that had in fact been refuted. Indo-European scholars should have scrapped all their historical reconstructions and started again from scratch. But that is not what happened. Vested interests and academic posts were involved. Almost without exception the scholars in question managed to persuade themselves that despite appearances the theories of the philologists and the hard evidence of archeology could be made to fit together. The trick was to think of the horse-riding Aryans as conquerors of the cities of the Indus civilization in the same way that the Spanish conquistadores were conquerors of the cities of Mexico and Peru or the Israelites of the Exodus were conquerors of Jericho. The lowly Dasa of the Rig Veda, who had previously been thought of as primitive savages, were now reconstructed as members of a high civilization.
