"In the days when historians supposed that history had begun with Greece, Europe gladly believed that India had been a hotbed of barbarism until the “Aryan” cousins of the European peoples had migrated from the shores of the Caspian to bring the arts and sciences to a savage and benighted peninsula. Recent researches have marred this comforting picture—as future researches will change the perspective of these pages. In India, as elsewhere, the beginnings of civilization are buried in the earth, and not all the spades of archeology will ever quite exhume them."
