The Vishnu Purana: Book IV: Chapter XIX

448:13 The Váyu, Matsya, and Bhágavata agree with our text in making these the grandsons of Tansu: even the Bráhma P. concurs, but the Hari V. makes them his sons, having apparently transformed Tansosuta, the son of Tansu, into a synonyme of Tansu, or Tansurodha; as in these parallel passages: 'The son of Tansu was the illustrious sage Dharmanetra: Upadánaví had from him four excellent sons.' Bráhma P. 'Tansurodha was a royal sage, the illustrious institutor of laws. Upadánaví had four sons from Tansurodha.' Hari V. The commentator explains Dharmanetra to be 'institutor p. 449 of laws.' We have Upadánaví before, as the daughter of Vrishaparvan the Daitya, married to Hirańyáksha. Hamilton (Buchanan) calls her the wife of Sughora. The four sons are named in other authorities, with some variations: Dushyanta, Sushyanta or Rishyanta or Sumanta, Pravíra and Anagha or Naya. The Mahábhárata enumerates five, Dushyanta, Śúra, Bhíma, Vasu, and Pravasu, but makes them the sons of Ílina and grandsons of Tansu.

449:14 These two Ślokas are taken from the Mahábhárata, Ádi Parvan, p. 112, and are part of the testimony borne by a heavenly messenger to the birth of Bharata. They are repeated in the same book, in the account of the family of Puru, p. 139. They occur, with a slight variation of the order, in other Puráńas, as the Váyu, &c., and shew the greater antiquity of the story of Śakuntalá, although they do not narrate it. The meaning of the name Bharata is differently explained in Śakuntalá; he is said to be so called from supporting' the world: he is also there named Śarvadamana, 'the conqueror of all.'
