  • Generality and iteration

    Open AccessTaro TokutakeARTICLEHistoria Mathematica2026

    The present paper explores the relationship between generality and iteration in algorithms for squaring and cubing as presented in Śrīdhara’s Sanskrit arithmetic treatise, the [Book] of Three Hundred [Verses] ( Triśatī ), along with its anonymous commentary. I first examine the structure of each algorithm as stated in the base text. I then interpret and reconstruct the procedures based on the descriptions in the commentary. Finally, I explore a s…

T…

    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 te…
