This Putumana wrote several other astronomical works also, of which the most important is the Nyāyaratna; none of these has been published. This tradition of astronomy in Kerala continued well into the nineteenth century, but the author of the Karaṇapaddhati is the last major figure. - [Previous: c4.s5.38](https://indike.org/pramana/ins.science.pingree-1981.c4.s5.38) - [Next: c4.s5.40](https://indike.org/pramana/ins.science.pingree-1981.c4.s5.40) - [Up: c4.s5](https://indike.org/pramana/ins.science.pingree-1981.c4.s5) ## Linked texts (1) - [Karaṇapaddhati](https://indike.org/pramana/in.astro.kerala.tantra.karanapaddhati) — Putumana Somayājī 1660, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c4.s5.39](https://indike.org/pramana/ins.science.pingree-1981.c4.s5.39) · Pramāṇa
