42 Systems of Sanskrit Grammar § 28 - ] was confined to the systems of grammar outside the Paniniya school. These we shall notice in another place. For Panini's school Kaiyyata's Pradipa marks the end of the second period of development. Kaiyyata was probably, as his name indicates, a native of Kaśmir. His father was Jaiyyata surnamed Upādhya- ya, and his preceptor was one Maheśvara. In a commen- tary on Mammata's Kavyaprakāśa written by Bhimasena (Samvat 1779=1722 A. D.) Kaiyyata along with Auvata has been spoken of as the disciple and even the younger brother of Mammata. This statement is inaccurate if by Auvata is meant the author of the Bhashya on the Yajur- veda-Samhitä, whose father was Vajrata; and since Bhimasena is a late writer we need not likewise attach much importance to the chronological relation between Mammata and Kaiyyata as suggested by him. Mammata was, we know, a great grammarian as well as a rhetori- cian who lived cir. 1100, and there is nothing improbable in his being a teacher to even Kaiyyata. Kaiyyata's lower limit is given by the circumstance that he is quoted in the Sarva-darśana-sangraha (cir. 1300).² Regarding the nature of Kaiyyata's performance it is not necessary in this place to say much. He tells us in his introduction that he followed on the lines of Hari, that is, Bhartrihari, and he may be pronounced to have been fairly successful on the whole in the task of interpreting the Mahabhashya. His work has been, 1 - at fe fat- f 2 Aufrecht's Oxford Catalogue, p. 247 a. Are we to suppose, therefore, that Kaiyyata had a complete manuscript of Bhartrihari's commentary on the Maha- bhashya before hin? In that case the Tripadi' alluded to in the Gaparatna-mahodadhi (above, p. 41) must be either a distinct work, or may be no other than the Vakyapadiya itself, which is in three chap- Lers,
