"Winternitz (1907), too, felt that since "all the external evidence fails, we are compelled to rely on the evidence out of the history of Indian literature itself, for the age of the Veda. . . . We cannot, however, explain the development of the whole of this great literature, if we assume as late a date as round about 1200 or 1500 B.C. as its starting point. We shall probably have to date the beginning of this development about 2000 or 2500 B.C." (310)."
