Aswathama as coming Vyasa
Source: The Vishnu Purana
From Book III, chapter 3.
Parasara (to Maitreya):
In every Dvapara (or third age), Vishnu in the person of Vyasa, in order to promote the good of mankind, divides the Vedas, which is properly but one, into many portions: Observing the limited preseverance, energy, and applications of mortals, he makes the Veda four-fold, to adapt it to their capacities; and the bodily form in which he assumes, in order to effect that classification, is known by the name of Veda Vyasa. Of the different Vyasas in the present Manvantara, and the branches which they have taught, you shall have an account.
Twenty eight times have the Vedas been arranged by the great Rishis in the Vaivasvata Manvantara in the Dvapara age, and consequently eight and twenty Vyasas have passed away; by who, in their respective periods, the Vedas have been divided into four.
In the first Dvapara age, the distribution was made by Svayambhu (Brahma) himself;
in the second, the arranger of the Veda (Veda-Vyasa) was Prajapati (or, Manu);
in the third Usanas,
in the fourth Vrhaspati,
in the fifth Savitri,
in the sixth Mrityu (Death or Yama),
in the seventh Indra,
in the eighth Vasistha,
in the ninth Sarasvata,
in the tenth Tridhaman,
in the eleventh Trivrishan,
in the twelveth Bharadvaja,
in the thirteenth Antariksha,
in the fourteenth Vapra,
in the fifteenth Trayyaruna,
in the sixteenth Dhananjaya,
in the seventeenth Kritanjaya,
in the eighteenth Rina,
in the ninetenth Bharadvaja,
in the twentieth Gotama,
in the twenty first Uttama, lso called Haryatma,
in the twenty second Vena who is like-wise named Rajasravas,
in the twenty third Somasushmapana also called Trinavindu,
in the twenty fourth Riksha, the descendent of Bhrgu, who is also known by the name Valmiki,
in the twenty fifth my father Sakti was Vyasa,
I was the was in the twenty sixth Dvapara,
and was succeeded by Jaratkaru.
The Vyasa of the twenty eighth, who followed him was Krishna Dvaipayana.
These are the twenty eight elder Vyasas by whom, in the preceding Dvapara ages the Veda has been divided into four.
In the next Dvapara, Drauni (son of Drona) will be the Vyasa, when my son Muni Krishna Dvaipayana, who is the actual Vyasa, shall cease to be (in that character).
