"Almost a century ago, Winternitz ([1907] 1962) was refreshingly forthright about the lack of agreement regarding even the approximate date of the Veda: "It is a fact, and a fact which it is truly painful to admit, that the opinions of the best scholars differ, not to the extent of centuries, but to the extent of thousands of years, with regard to the age of the Rg Veda. Some lay down the year 1000 B.C. as the earliest limit for the Rg Vedic hymns, while others consider them to have originated between 3000 and 2500 B.C." (253)."
