It was, however, probably during this period that a group of minor siddhāntas belonging to the Saurapakṣa, but attributed to deities or sages, were written. These are the Somasiddhānta,⁸⁵ on which a commentary, Gūḍhārthadīpikā, was composed by Nṛsiṃha⁸⁶ at Koṇḍavīḍu in Āndhrapradeśa in about 1400; a Vasiṣṭhasiddhānta⁸⁷ which claims to be based on that of Viṣṇucandra; a Vṛddhavasiṣṭhasiddhānta,⁸⁸ which is influenced by the Brāhmapakṣa in its planetary equations; and the Brahmasiddhānta⁸⁹ alleged to be part of a Śākalyasaṃhitā. - [Previous: c4.s2.74](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.74) - [Next: c4.s2.76](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.76) - [Up: c4.s2](https://indike.org/pramana/ins.science.pingree-1981.c4.s2) ## Linked texts (3) - [Vāsiṣṭhasiddhānta](https://indike.org/pramana/in.astro.siddhanta.early.vasistha) — Sanskrit - [Gūḍhārthadīpikā](https://indike.org/pramana/in.niti.dharma.nibandha.nirnaya.gudharthadipika) — Vāmadeva, Sanskrit - [Siddhāntaśiromaṇi](https://indike.org/pramana/in.astro.siddhanta.early.siddhantasiromani) — Bhāskara II, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c4.s2.75](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.75) · Pramāṇa
