From this general survey of the Vedic period we now turn to a more detailed consideration of the different phases of the literature it produced.
Chapter III
The Rigveda
In the dim twilight preceding the dawn of Indian literature the historical imagination can perceive the forms of Aryan warriors, the first Western conquerors of Hindustan, issuing from those passes in the north-west through which the tide of invasion has in successive ages rolled to sweep over the plains of India. The earliest poetry of this invading race, whose language and culture ultimately overspread the whole continent, was composed while its tribes still occupied the territories on both sides of the Indus now known as Eastern Kabulistan and the Panjāb. That ancient poetry has come down to us in the form of a collection of hymns called the Rigveda. The cause which gathered the poems it contains into a single book was not practical, as in the case of the Sāma- and Yajur-veda, but scientific and historical. For its ancient editors were undoubtedly impelled by the motive of guarding this heritage of olden time from change and destruction. The number of hymns comprised in the Rigveda, in the only recension which has been preserved, that of the Çākala school, is 1017, or, if the eleven supplementary hymns (called Vālakhilya) which are inserted in the middle of the eighth book are added, 1028. These hymns are grouped in ten books, called maṇḍalas, or “cycles,” which vary in length, except that the tenth contains the same number of hymns as the first. In bulk the hymns of the Rigveda equal, it has been calculated, the surviving poems of Homer.
The general character of the ten books is not identical in all cases. Six of them (ii.–vii.) are homogeneous. Each of these, in the first place, is the work of a different seer or his descendants according to the ancient tradition, which is borne out by internal evidence. They were doubtless long handed down separately in the families to which they owed their being. Moreover, the hymns contained in these “family books,” as they are usually called, are arranged on a uniform plan differing from that of the rest. The first, eighth, and tenth books are not the productions of a single family of seers respectively, but consist of a number of groups based on identity of authorship. The arrangement of the ninth book is in no way connected with its composers; its unity is due to all its hymns being addressed to the single deity Soma, while its groups depend on identity of metre. The family books also contain groups; but each of these is formed of hymns addressed to one and the same deity.
Turning to the principle on which the entire books of the Rigveda are arranged in relation to one another, we find that Books II.–VII., if allowance is made for later additions, form a series of collections which contain a successively increasing number of hymns. This fact, combined with the uniformity of these books in general character and internal arrangement, renders it probable that they formed the nucleus of the Rigveda, to which the remaining books were successively added. It further seems likely that the nine shorter collections, which form the second part of Book I., as being similarly based on identity of authorship, were subsequently combined and prefixed to the family books, which served as the model for their internal arrangement.
The hymns of the eighth book in general show a mutual affinity hardly less pronounced than that to be found in the family books. For they are connected by numerous repetitions of similar phrases and lines running through the whole book. The latter, however, does not form a parallel to the family books. For though a single family, that of the Kaṇvas, at least predominates among its authors, the prevalence in it of the strophic form of composition impresses upon it a character of its own. Moreover, the fact that the eighth book contains fewer hymns than the seventh, in itself shows that the former did not constitute one of the family series.
The first part (1–50) of Book I. has considerable affinities with the eighth, more than half its hymns being attributed to members of the Kaṇva family, while in the hymns composed by some of these Kaṇvas the favourite strophic metre of the eighth book reappears. There are, moreover, numerous parallel and directly identical passages in the two collections. It is, however, at present impossible to decide which of the two is the earlier, or why it is that, though so nearly related, they should have been separated. Certain it is that they were respectively added at the beginning and the end of a previously existing collection, whether they were divided for chronological reasons or because composed by different branches of the Kaṇva family.
As to the ninth book, it cannot be doubted that it came into being as a collection after the first eight books had been combined into a whole. Its formation was in fact the direct result of that combination. The hymns to Soma Pavamāna (“the clearly flowing”) are composed by authors of the same families as produced Books II.–VII., a fact, apart from other evidence, sufficiently indicated by their having the characteristic refrains of those families. The Pavamāna hymns have affinities to the first and eighth books also. When the hymns of the different families were combined into books, and clearly not till then, all their Pavamāna hymns were taken out and gathered into a single collection. This of course does not imply that the Pavamāna hymns themselves were of recent origin. On the contrary, though some of them may date from the time when the tenth book came into existence, there is good reason to suppose that the poetry of the Soma hymns, which has many points in common with the Avesta, and deals with a ritual going back to the Indo-Iranian period, reached its conclusion as a whole in early times among the Vedic singers. Differences of age in the hymns of the ninth book have been almost entirely effaced; at any rate, research has as yet hardly succeeded in distinguishing chronological stages in this collection.
