[ - § 41 Accessory Treatises paribhashas that eventually it has become, for the Päni- niya student, the hardest nut to crack. This feat has usually been attempted in the body of the commentaries themselves. Regular treatises specially dealing with paribhashas come much later. Perhaps the earliest known is that of Siradeva, who is quoted in the Madhaviya-Dhātu- vritti. Nägesa's Paribhashendusekhara contains the most popular exposition of the paribhashas, and it has been commented upon by Payagunda, Bhairavamisra, Seshasar- man, Bhimabhatta, and many others. Non-Paniniya schools copied most of their paribhashas from Panini, the earliest of them being the Kätantra for which Durgasimha put together a list of paribhashas and wrote a commmentary on the same. 55 This is also the place where we can introduce a host of treatises on the philosophy of grammar--dealing with questions such as the nature of sound, the connection between word and its meaning or of sentence and its com- ponent parts, and so forth. The issues have been raised and dealt with in the Mahabhäshya itself, and later writers have derived most of the material for their lucubra- tions from that source. The earliest of such treatises is the Vakvapadiva of Bhartrihari and the latest deserving a special mention is the Vaiyakaranasiddhantabhashana of Kondabhatta, a commentary on which was written by Nagesa. A multitude of smaller and larger lights came in between. The works are mainly special mono- grams on particular topics, the karaka relations alone having engaged over forty writers of different schools and opinions. 41. Résumé of the history of the Paniaiya school-Here per- haps we may draw a deep breath and, before proceeding with the history of the non-Paniniya schools of grammar, cast a hurried glance over the field that we have already travelled.
