Vishnupurana 3.4.p2

3.4.p2

As the Veda was divided by the intelligent Veda-Vyāsa, to it was divided at various other periods by myself and other Vyāsas. In this way, O foremost of twice-born ones, the Veda is divided into various branches and the people of the four Yugas perform sacrifices. O Maitreya, know this Krishna Dwaipāyana Vyāsa, as the Nārāyana, for who else on this earth could have composed the Mahabhārata? How in the Dwāpara age the Veda was divided by my high-souled son, I shall describe, O Maitreya, do thou hear it.
