I and of astronomy in its Pt. II. The Sanskrit version of this work, known as \*Gaṇitayuktibhāṣā\*, is also, in all probability, his work. An old astronomical document informs that he was the pupil of Dāmodara of Vaṭaśreṇi and was a member of the Paraṅnoṭṭu family³ of the Ālattūr village in South Malabar.⁴ Nilakaṇṭha Somayāji, whose \*Tantrasaṅgraha\* he mentions towards the beginning of his work, was his respected elder. He himself was the teacher of Acyuta Piṣāraṭi who mentions him in reverential terms at the close of his \*Uparāgakriyākrama\* (A.D. 1592). M. Whish records a tradition that the author of the \*Yuktibhāṣā\* was the author also of a \*Dṛkkaraṇa\*⁵ The \*Dṛkkaraṇa\* in question, which is now available in a single manuscript, is a comprehensive metrical treatise in Malayalam on astronomy. It does not give anywhere the name of its author, but gives in its last verse, its date of composition in the words \*kolambe barhiśūnau\* (M.E. 783 = A.D. 1608). In view of this date and the mention of the tradition recorded by Whish, it is quite possible that this is a work of Jyeṣṭhadeva.⁶ - [Previous: c10.s6.62](https://indike.org/pramana/ins.science.sarma-1972.c10.s6.62) - [Next: c10.s7.2](https://indike.org/pramana/ins.science.sarma-1972.c10.s7.2) - [Up: c10.s7](https://indike.org/pramana/ins.science.sarma-1972.c10.s7) ## Cites (2) - [Tantrasaṅgraha](https://indike.org/pramana/in.astro.kerala.tantra.tantrasangraha) — Nīlakaṇṭha Somayājī 1500, Sanskrit - [Yuktibhāṣā (Gaṇitayuktibhāṣā)](https://indike.org/pramana/in.astro.kerala.golayukti.yuktibhasa) — Jyeṣṭhadeva 1520, Malayalam --- Source: [https://indike.org/pramana/ins.science.sarma-1972.c10.s7.1](https://indike.org/pramana/ins.science.sarma-1972.c10.s7.1) · Pramāṇa
