Quotes

• ... the "invasion model" ... has been supplanted by much more sophisticated models over the past few decades... This development has not occured because Indologists were reacting, as is now frequently alleged, to current Indian criticism of the older theory. Rather, philologists first, and archaeologists somewhat later, noticed certain inconsistencies in the older theory and tried to find new explanations, a new version of the immigration theories.
