Makarandasarini
Makarandasāriṇi is a Sanskrit astronomical table text composed by the Indian astronomer-mathematician Makaranda hailing from Varanasi. In the Sanskrit astronomical literature such table texts are referred to as sāriṇi-s or koṣṭhaka-s. It is one of the most popular such texts ever composed in Sanskrit.
Important features
Makarandasāriṇi follows the Saurapakṣa. This is the midnight-epoch system embodied in a recension of the Sūryasiddhānta dating to around the eighth century. This is reflected in the choices of the values of the fundamental parameters, like the values of the celestial bodies’ revolution-numbers and consequent mean velocities. Another unique feature of Makarandasāriṇi is the use of vegetation-themed Sanskrit technical terms for its various tables. The table giving the mean position increments has been called vāṭikā and the table giving calendar day/time for mean time unit has been called guccha. There are tables named valli-s and saurabhaṃ-s. In comparison to most other sāriṇi-s or koṣṭhakā-s, Makarandasāriṇi has no accompanying set of verses except for an invocatory stanza at the beginning of the text.Contents
