Vedas are not materially different from those of the Rig-Veda. On the Rig-Veda they are all founded; this is the fundamental Veda, or great Veda; and in knowing this one we should know all. The other three, according to Max Müller, contain "chiefly extracts from the Rig-Veda, together with sacrificial formulas, charms, and incantations" (Chips, vol. i. p. 9). It must not therefore be imagined that we have in these four Vedas four different collections of hymns. They are rather four different versions of the same collection, the Sâma-Veda, for instance, containing but seventy-one verses which are wanting in the Rig-Veda (S. V., p. xxviii), and being otherwise "little more than a repetition of the Soma Mandala of the Rich" (Wilson, vol. i. p. xxxvii), or of that book of the Rig-Veda which is devoted to the god Soma. The Atharva-Veda-Sanhitâ is indeed to a certain extent an exception; belonging to a later age, it has some hymns altogether peculiar to itself, and its fifteenth book "has something of the nature of a Brâhmana" (O. S. T., vol. i. p. 2). It must be noted, moreover, that of the Yajur-Veda there are two different versions, the Black and the White Yajur-Veda, said to have descended from two rival schools. The hymns of the first are termed the Taittiriya-Sanhitâ, those of the second the Vâjasaneyi-Sanhitâ.
The origin of those four distinct, yet not different Vedas, is thus explained. In certain sacrifices, formerly celebrated in India, four classes of priests were required, each class being destined for the performance of distinct offices. To such of these classes was assigned one of the Vedas, which contained the hymns required by that class. Thus the Sâma-Veda was the prayer-book of the Udgâtri priests, or choristers, who chant the hymns. The Yajur-Veda was the prayer-book of the Adhvaryu priests, or attendant ministers, who prepare the ground, slay the victims, and so forth. The Atharva-Veda was said to be intended for the Brahman who was, according to one of the Brâhmanas, the "physician of the sacrifice;" the general superintendent who was to tell if any mistake had been committed in it (A. B., 5. 5.—vol. ii. p. 376). For the fourth class, the Hotri priests, or reciters of hymns, no special collection was made in the form of a liturgy. They used the Rig-Veda, a collection of the hymns in general without any special object, and they were
