c4.s4.t10.1
Acyuta Piṣāraṭi, a non-Brāhmin astronomer mathematician of Kerala was a student of Jyeṣṭhadeva. His *Karaṇottama*² is a manual of mathematics in five chapters containing 109 verses. In a verse³ of his astronomical work, *Uparāgakriyākrama*,⁴ he expressed that at the time of composition of this work, Jyeṣṭhadeva had become very old, but was still alive. He belonged to Piṣāraṭi community and referred to as Vaiṣṇava whose function was to look after the external affairs of the temple. His pupil, Nārāyaṇabhaṭṭa gives the date of his death as 1621 A.D. from the study of a chronogram.⁵
