The Mitanni Evidence From Paul Thieme, 'The "Aryan" Gods of the Mitanni Treaties', JAOS, Vol. 80, 1960, pp. 301-317. "...Kikkuli's treatise in Hittite on horse training (numerals: aika-one, tera -three,panza -- five, satta -- seven, na(ua) -- nine; appellatives: uartana -- circuitm course (in which horses move when being trained), as'ua-- horse, and, finally, a series of names of Aryan divinities on a Mitanni-Hatti and a Hatti-Mitanni treaty (14th century BC)... a key question is whether these data should be interpreted as traces of specifically Indo-Aryan speech and religion, or whether they should rather be identified as Proto-Aryan... an answer to it would have considerable historical implications. The historian will devise a theory to explain how 'Indians', or 'Proto-Indians', or 'Para-Indians', or 'Proto-Aryans' could come into Western Asia and exercise influence inferable from these linguistic traces. The linguist is entitled to be more modest. At the first step, he will not attempt to offer an explication in terms of a hypothesis, but to reach a factual decision on the linguistic character of the terms that confront him... It is easy to see that in each case where there exists a clearly recognizable difference between Indo-Aryan and Iranian, the terms and names of the Akkadian and Hittite documentation (as far as they are safely identifiable) side with Indo-Aryan-- s in intervocalic or prevocalic initial positions, which in Iranian appears as h, is preserve: nas'aattiia- (Mitanni treaty); Sanskrit Na_satya, but Iranian *Na_ha0ya (Av. Na_nhai0ya); satta- (Kikkuli): Sanskrit sapta, but Iranian hafta, hapta; the numeral 'one' is aika- (Kikkuli): Sanskrit eka, but Iranian aiva. However, it is not possible to deny that the forms Na_satya, sapta and a numeral aika might be Proto-Aryan. As far as s is concerned, Indo-Aryan preserves the old situation while Iranian has innovated; as to aika, the possibility must be admitted that both *aika and *aiva were Proto-Aryan and that the exclusive adoption of *aika in Indo-Aryan and of aiva in Iranian is the result of a later development. The fact that Proto-Aryan *ai and *au are replaced in Indo-Aryan by e and o, while in old Iranian they are preserved as ai and au and that ai and au regularly appear on the Anatolian documents (e.g., Kikkuli's aika), is unfortunately inconclusive... In his essay, 'The Aryan Gods of the Mitani People (Kristinania Etnografiske Museums Skrifter Bind 3 Hefte 1; Kristiania, 1921), Sten Konow vigorously maintained that a clear-cut difference between Proto-Aryan and Indo-Aryan divine nomenclature necessarily has to be asumed, and that by taking into account this difference it becomes possible to settle the Indo-Aryan (Vedic) nature of the gods named as witnesses on the treaties. Sten Konow's arguments have been unduly neglected by several contemporary scholars. It is, for instance, hard to accept T. Burrow's statement (Sanskrit Language, p. 30): "It is only the antiquity and conservativism of the Indian tradition, as opposed to the Iranian, that has led scholars to regard these Aryas (in the Mitanni realm) as specifically Indo-Aryan." One of Konow's chief points was that the Vedic Indra must be distinguished from a presumable Proto-Aryan *Indra and that the particular role he plays in the RV alone can be held responsible for his appearing in the Mitanni treaty in the company of Mitra and Varun.a. Nor do I find it possible to concur with Mayrhofer's charecterization of the relation of Vedic and Iranian to Proto-Aryan religion (Die Sprache, Vol. V, p. 90: "Bei den Gutternamen (war)... was uns nur im Veda in voller Blute erscheint, doch mit Sicherbeit (sic!) bereits im Gemeinarischen, aber ebenso wohl im vorzarathustrischen Iranischen vorhanden..."), whiich while being in full harmony with views held and expressed by H. Oldenbern in his time (cf., e.g., JRAS 1909, pp. 1096-1098), cannot be derived wth any cogency from our actual data, and rather rests on highly questionable simplifications....To be correct, Burrow's verdict might well have to be inverted: It is only the unquestioning acceptance of the conservativism of the Indian tradition, as opposed to the Iranian, that has led some scholars to regard the Aryan gods of the Mitanni treaty to be Proto-Aryan.... "The lists of the Aryan gods on the Hatti-Mitanni (KBo I 1 and duplicates) and the Mitanni-Hatti (KBo I 3) treaties read:... mi-it-ra-as'-si-il... in-dar na-s'a-a (t-ti-ia-a)n-na... mi-it-ra-as'-s'i-il a-ru-na-as'-s'i-il in-da-ra na-s'a-at-ti-ia-an-na It cannot be doubted, and indeed never was, that the onomastic elements of these texts, which are given in italics in my transcription, have exact equivalents in Vedic religious poetry. Here the stem forms of the names quoted would read: Mitra-, Varun.a-, Indra-, Na_satya-... If further asked to name a Rigvedic verse in which these names appear side by side and in this orde,r he would have to quote RV 10.125.1bc: aham mitra_-varun.a_ ubha_ bibharmi aham indra_gni_ aham as'vina_ ubha_ "I (Speech) carry (support, nourish, or bear-- in my womb) both Mitra and Varun.a, I (carry) Indra- Agni, I (carry) both the two As'vins"...It is the merit of G. Dumezil (Les dieux des Indo-Europeens, Paris 1952, p. 9ff.) to have pointed out the analogy of the Mitanni series and that of RV 10.125.1bc...There is no justification for obliterating this potential clue by choosing to quote the gods of the Mitanni treaties in an arbitrarily changed order (Burrow, opcit, p. 28)... The name Varun.a is spelt in two different ways... u-ru-ua-na; a-ru-na... it represents an actual variant of the name, introduced by a Hittite who connected with Hittite aruna- 'sea'. Varun.a is, in fact, closely associated with the waters, especially the 'sea' (samudra), in the RV... the compound mitra_varun.a_ was divided incorrectly, not into the two duals mitra_ and varun.a_, but into the duals *mitra_u and *arun.a_... "...the obvious presumption is that the Aryan gods in the list are gods of the royal family-- and perhaps of part of the nobility-- while the Mitanni gods are those of the 'Hurri people "...Do Mitra, Varun.a, Indra and the two Na_satyas protect treaties in the RV? and: Is it likely or provable that they did so in Proto-Aryan times? To the first question a strictly factual answer can be given: all the named gods indeed are said to protect treaties in the RV, even the two Na_satyas, though these only ocasionally. The second one cannot be answered with the same confidence, since we have no primary sources of Proto-Aryan religion and must rely upon the resources of techniques of reconstruction... A reconstruction (of Proto-Aryan religion) can be attempted only by a careful confrontation of Vedic and Avestan terminology. Such confrontation yields the result that but one name in the Mitanni list can be postulated safely as that of a Proto-Aryan god whose function it was to protect treaties-- *Mitra m. 'Contract, Treaty'. All the other items of the list are doubtful with respect either to the form of the name or to the functions of the god in Proto-Aryan times." http://sarasvati.simplenet.com/mesopnew/mitanni.htm
