________________ xxiii lun and lrn of P and J; len, term coined by. S, is equivalent of P, J lin in the sense of potential. Sakatayana's araic, however, does not tally with the Katantra's definition of vrddhi as ar, ai, au, because the Amoghvitti, e. g. on 'Araico 'ksvadeh' (2.3.84) informs us that ar is made up of a, which is met with in Panini's definition of Vrddhi (P. 1.1.1), and ar. Unlike Panini's 14 Sivasutras, and like C and J(A), sakatayana has 13 Sivasutras, in which Panini's 5th and 6th are combined into one, viz., hayavaralan, but with one improvement in S, as compared with P, C and J(s), that the Anubandhan employed twice by these three works has been replaced in the 5th by n, thus removing the ambiguity. Thus, the Anubandha n in the 5th Sivasutra represents an innovation of sakatayana84. According to P. Kielhorn, Sakatayana's grammar holds an important place in the later grammatical literature of India. As far as the Sabdanusasana of Sakatayana is concerned, there exists a separate collection of Paribhasa. It contains the Linganusasana after the rule S 1.2.1. The Unadis are given in the Sutras 4.3.280 onwards and in the Amoghavrtti. The Sakatayana-Dhatupatha enumerates nine dhatuganas, viz., adadi (4.3.21), hvadi (4.3.21), divadi (4.3.22), svadi (4.3.28), tudadi (4:3:32), rudhadi (4.3.34), tanadi (4.3.33), kryadi (4.3.30) and curadi (4.1.7). The Amoghavrtti represents a work belonging to the class of Brhadvrttis. The Kasika is sakatayana's model in writing the Amoghavrtti, and in it he depends upon the former. Moreover, Sakatayana is largely indebted to the author Jinendrabuddhi of Nyasa on the Kasika, for the material of his sutras and his Amoghavrtti. He refers very often to the views of other grammarians85. The decline of sakatayana's system is, according to Belvalkar, due to 'Hemacandra's Sabdanusasana, which may be rightly called an improved edition of Sakatayana's86. 4.5 Buddhisagara is said to have consulted the Vibrantavidyadhara Vyakarana of Vamana (between 300 to 550 A. D.) before composing his Pancagranthi Vyakarana. Vardhamana, the author of the Ganaratna-mahodadhi has referred to the work by name and to him by the eulogistic 'sahrdayacakravarti'87. Hemacandra (12th cent. A. D.) has mentioned Visrantavidyadhara in his auto-commentary on his Siddhahaima-Sabdanusasana. Prabhacandra has mentioned, in the Mallavadi Prabandha of his Prabhavakacarita, that Mallavadi composed a Nyasa commentary on Vamana's Visrantavidyadhara88. According to Yudhisthira Mimamsaka, Mallavadi was a contemporary of king Siladitya of Valabhi where the former defeated the Buddhists in a debate and dislodged them from the place. Valabhi was destroyed by the Mlecchas in about 318 A. D. Vamana is said to have
