Tilak developed his ideas on the Vedas in this second work on the origins of the Vedas, forming a sequel to his book The Orion (1893). In the present work, he argued that the Vedas could only have been composed in the Arctic, and that their originators brought them south after the onset of the past ice age, about 8000 BC. Based on certain remarks made in the Vedas themselves, Tilak writes “when we put them side by side with what we know of the Glacial and the Post-glacial epoch from the latest geological researches, we cannot avoid the conclusion that the primitive Aryan home was both Arctic and inter- glacial” (p. vii).
