itxxii ÄRYABHATIYA works 2' he explains : “In the Dasagitika is to be found, at the beginning, (i.e., in Gitika, 1), the (formal) invocation, mention of authorship and the subject to be treated. And, at the close, (vs. 13), is found the concluding statement of the benefits of the study (of the work). Hence this is a complete treatise. (Similarly), at the beginning of the other tract (Ganita, 1) also, are to be found an invocation, mention of authorship and the subject to be treated. And, at the end (Gola, 50) (is found), a (formal) conclusion indicating also the title of the treatise. Hence, it is a different work. Thus, the discipline definitely consists of two works.' (com. on Gitika, 12, p. 31 ; see also p. 5). It may be noted that the same view has been expressed by the commentators Bhāskara, Someśvara and Raghunātha-rāja. 3. Identification of the Ten Gitikās Of the thirteen verses contained in the Gitikapada, there is difference of opinion among commentators about the identification of the 'ten' (dasa) gitikas which constitute the teachings of Brahma. It is accepted on all hands that verses 1 and 13 are, respectively, the invocatory and concluding verses and so are not included in the "ten'. While commentator Paramesvara holds vss. 3-12 as the "ten gittkas, taking vs. 2 as a mere paribhasa ("interpretative definition'), Suryadeva considers vss. 2-11 as the "ten gitikas, excluding vs. 12, which enumerates the R-sines which are, of course, otherwise derivable. Moreover, according to him, verse 12 is couched in the arya metre, and not in the giti metre. Thus, speaking about the enunciation of the discipline, which Aryabhata imbibed from Brahma, he says : "Then that teacher Aryabhata enunciated all instructions of a seminal nature in 'ten' giti stanzas and that of a secondary nature relating to general mathematics as envisaged by his own mind in a single arya verse and propounded them before the world.' (Cf. General introduction to the com., p. 5). He expresses the same view also in his commentary to i. 12 (p. 31). It may be noted that in the form in which vs. 12 is given by Suryadeva, it is not in the giti metre, but in the arya metre, though not a perfect arya.' 1. For a discussion on this topic, see Pt. I, pp. 31-32.
