While discussing the issue of chronology, S B Roy has undertaken an indepth study of sources of historical research and basing his findings on the main pillars of his chronology, he has averred that the entire Veda could be conveniently divided into three broad chronological divisions as follows:
Early Vedic Age : Dynasty Number= D.N. 1 to D.N. 62 i.e.the hymns (if any) composed by Rishis having these dynastic numbers will belong to the division now called Early Vedic Age.
Middle Vedic Age : D.N. 63 to D.N. 68.
Late Vedic Age : D.N. 69 to D.N. 96.
He has thoroughly examined the Middle Vedic Age to find out the locale of of the Vedic People from the hymns themselves of Rig Veda. To solve the problem he relies on the hymns of Shyavashwa Atreya who belonged to D.N. 64 because the Rishi has extensively described the rivers crossed by Atreya Storm troopers.
Shyavashwa Atrey [R.V. 5 (52,53,61] mentions several rivers. They are :
R.V. V.53.9 mentions the rivers Rasa, Anitabha, Kumbha, Kruma, Sindhu and Saryu. Rasa has been indentified a the river Jaxtartes (Syr Dariya) in Turan i.e. South Russia. Kubha [Kabul River] and Krumu [Kurram River] are western tributaries of the river Indus and situated in Modern Afghanistan i.e. the Vedic Gandhara. Sindhu is the Indian River Indus.
Saryu in the context of the present enumeration, is probably the Iranian river Horayu and the river Saryu of eastern U P.
R.V. 5.52.9 mentions Parushni, the river Ravi of the Punjab.
Gomati [RV 5.61] has been identified as the river Gomal of Baluchistan by Pargiter and Keith.
Yamuna [RV 5.52.17 ] appears to be the modern Yamuna, marking perhaps the eastern limit of Aryana.
S.B. Roy in Aryan invasion and the Rigveda: A chronological reappraisal, pp165-176 writes on the basis of the above identification of the Rivers mentioned in the Rig Veda, "The habitat of the Vedic people when Shyavashwa [D.N.64] composed the hymn was, therefore, Turan, Iranm Gandhara [Afghanistan] and the Indian region, and perhaps, India up to the river Yamuna." He goes on to add that at this point of time, "the whole of Aryana--from Zagrus Mountains in the west to Jamuna in the east, and from Turan in the north to the Arabian seas in the south was the Vedic Land. The later nadi-stuti R.V. X.75 by Sindhukshita, the sib (?) of Priyamedha, describes the rivers of Punjab and also Ganga, and therefore, it could be said that when Shyavashwa Atrey [D.N. 64] wrote, the invasion was not complete but it was in the offing: when Sindhukhsita [D.N. 68?] wrote his hymn the Aryans had reached and settled in Ganga. To be more specific, the Vedic people were still mainly on the west of Indus when D.N. 64 composed in the hymn i.e. it was the age of transition into India."
Before proceeding further, the comments of the participants supported by sources in the discussion are invited on this hypothesis of S.B. Roy. After thourough discussion when this issue is settled in the form of making a workable hypothesis then, we shall proceed to next step.
