Ranganātha
v2.c12.s2.t72.1
He was born in the famous family of scholars at Golāgrāma (see genealogical table on page 154). His birth year may be about 1534. He wrote the ‘Mitabhāṣiṇī’, a commentary on the Siddhānta śiromaṇi. Sudhākara writes that he had compiled an independent work, named Siddhānta Cūḍamaṇi. It has 12 chapters and contains 400 verses. It follows the Sūryasiddhānta. Ranganātha has mentioned the date of its compilation as follows :—
v2.c12.s2.t72.2
मासानां कृतिलब्धि ४ हृद्युतिरसौ खाब्जैर्विहीना तिथि
वर्णै ५ हं दद्वि २ हतोऽवासर्मितिर्वारंग ६ भामात्वदं ।।
पक्षः सर्वयुतिः शको द्विषदिनै १५०२ युक्ता ।
v2.c12.s2.t72.3
Translation :—
v2.c12.s2.t72.4
Calculation based on the above data shows that this work was completed on Friday (6), the full moon (15) day of Pauṣa* (10), Śaka 1565**, the nakṣatra and the yoga on that day being Ārdrā (6) and Brahma (25) respectively.
v2.c12.s2.t72.5
∗ Sudhākara has arrived at Śaka 1562 as the date referred to in this verse ; but it is an error due to oversight. The third nakṣatra that he mentions was not possible on the fullmoon day of Pauṣa in that Śaka year. The nakṣatra happens to be the sixth ; and taking that into account, the sum would not come to 1562.
v2.c12.s2.t72.6
∗∗ The month seems to have been puzzled out by trial and error as the original verse does not contain any clue to its name or number. Pt. Sudhākara also remarks that number 10 has to be presumed here as the number of the month because it fits the case completely. (R. V. V)
