Systems of Sanskrit Grammar § 70 - 1 Unadipatha and the Dhätupatha by Durgasimha the author of the vritti. The Dhatupatha is modelled upon that of Chandragomin, with only slight modifications. The genuine Kalapa-Dhatusitra, which differs considerably from the above, is now reported to exist only in a Tibe- tian translation. 90 71. History of the Katantra school in Bengal. No definite information exists as to when the Kätantra was introduced into Bengal. In the fifteenth and sixteenth centuries there arose in Bengal a host of commentators and writers of supplements to the Kätantra, and the grammar is there to this day most assiduously studied. Some of the most famous of these Bengali writers are: i. Kaviraja who quotes Trilochanadasa and is quoted by Harirāma; ii. Kulachandra who is quoted by Ramadasa; Gopinātha Tarkacharya who is commented upon by Ramachandra who also wrote a commentary on the Kätantravrittipan- jikā; iii. Śrīpati who wrote a supplement to the Katan- tra which is honoured with commentaries written by Gopinatha Tarkacharya, Ramachandra Chakravarti, Śiva- rāma Chakravarti, and Pundarīkāksha; iv. Trilochana (not the older Trilochanadasa) who wrote an Uttarapari- sishta, giving therein such information on rg, afa, and as had escaped Sripati; and several others. Most of these writers came from the Vaidya community of Bengal, and their object in all cases has been, by partial or wholesale borrowing from all available sources, to make the Katantra as complete and up-to-date as possi- ble, so as to prevent its being neglected in the course of the struggle for existence which began with the modern revival of Panini under the auspices of the Kaumudikāras, and the simultaneous springing into existence of a large number of other modern schools of grammar. At present, as before observed, the study of the Kätantra is confine! to only a few districts of Bengal.
