Finally, the Purāṇas not only regularly speak of the fourfold Veda, but assign to the Atharva the advanced position claimed for it by its own ritual literature. Thus the Vishṇu Purāṇa connects the Atharva with the fourth priest (the brahman) of the sacrificial ritual.
Nevertheless a certain prejudice has prevailed against the Atharva from the time of the Dharma Sūtras. This appears from the fact that, even at the present day, according to Burnell, the most influential Brahmans of Southern India still refuse to accept the authority of the fourth Veda, and deny its genuineness. A similar conclusion may be drawn from occasional statements in classical texts, and especially from the efforts of the later Atharvan writings themselves to vindicate the character of their Veda. These ritual texts not only never enumerate the Vedas without including the Atharva, but even sometimes place it at the head of the four Vedas. Under a sense of the exclusion of their Veda from the sphere of the sacrificial ritual, they lay claim to the fourth priest (the brahman), who in the Vedic religion was not attached to any of the three Vedas, but being required to have a knowledge of all three and of their sacrificial application, acted as superintendent or director of the sacrificial ceremonial. Ingeniously availing themselves of the fact that he was unconnected with any of the three Vedas, they put forward the claim of the fourth Veda as the special sphere of the fourth priest. That priest, moreover, was the most important as possessing a universal knowledge of religious lore (brahma), the comprehensive esoteric understanding of the nature of the gods and of the mystery of the sacrifice. Hence the Gopatha Brāhmaṇa exalts the Atharva as the highest religious lore (brahma), and calls it the Brahmaveda. The claim to the latter designation was doubtless helped by the word brahma often occurring in the Atharva-veda itself with the sense of “charm,” and by the fact that the Veda contains a larger amount of theosophic matter (brahmavidyā) than any other Saṃhitā. The texts belonging to the other Vedas never suggest that the Atharva is the sphere of the fourth priest, some Brāhmaṇa passages expressly declaring that any one equipped with the requisite knowledge maybe a brahman. The ritual texts of the Atharva further energetically urged that the Purohita, or domestic chaplain, should be a follower of the Atharva-veda. They appear to have finally succeeded in their claim to this office, doubtless because kings attached great value to a special knowledge of witchcraft.
The geographical data contained in the Atharva are but few, and furnish no certain evidence as to the region in which its hymns were composed. One hymn of its older portion (v. 22) makes mention of the Gandhāris, Mūjavats, Mahāvṛishas, and Balhikas (in the north-west), and the Magadhas and Angas (in the east); but they are referred to in such a way that no safe conclusions can be drawn as to the country in which the composer of the hymn in question lived.
The Atharva also contains a few astronomical data, the lunar mansions being enumerated in the nineteenth book. The names here given deviate considerably from those mentioned in the Taittirīya Saṃhitā, appearing mostly in a later form. The passage in which this list is found is, however, a late addition.
The language of the Atharva is, from a grammatical point of view, decidedly later than that of the Rigveda, but earlier than that of the Brāhmaṇas. In vocabulary it is chiefly remarkable for the large number of popular words which it contains, and which from lack of opportunity do not appear elsewhere.
It seems probable that the hymns of the Atharva, though some of them must be very old, were not edited till after the Brāhmaṇas of the Rigveda were composed.
On examining the contents of the Atharva-veda more in detail, we find that the hostile charms it contains are directed largely against various diseases or the demons which are supposed to cause them. There are spells to cure fever (takman), leprosy, jaundice, dropsy, scrofula, cough, ophthalmia, baldness, lack of vital power; fractures and wounds; the bite of snakes or injurious insects, and poison in general; mania and other ailments. These charms are accompanied by the employment of appropriate herbs. Hence the Atharva is the oldest literary monument of Indian medicine.
The following is a specimen of a charm against cough (vi. 105):—
Just as the soul with soul-desires
Swift to a distance flies away,
