Triśatībhāṣyaの著者の在所と年代に関する一考察――算術表現と言語的特徴の分析を通じて――

抄録

The present paper attempts to determine the place and date of the author of the Triśatībhāṣya, an anonymous commentary on the Triśatī of Śrīdhara （ca. 800 CE）, through an analysis of its arithmetic expressions and linguistic features. The four examples dealt with in this paper are: I） bhāgāhāra; II） bārapaṃcajaṃ 60; III） dūṇa; and IV） an example from an unknown work in Apabhraṃśa. Of these, I） and II）, especially bāra, have the same usage in a text written in Old Gujarati, and III） and IV） come from Apabhraṃśa or New Indo-Aryan. This suggests that the author of the Triśatībhāṣya flourished in West India some time between the 12th and 15th centuries CE.
