A twelfth century set of astronomical tables, the Brahmatulyasarini by Bhaskara II (b. 1114), poses some interesting challenges for the modern historian. While these tables exhibit a range of standard issues that numerical data typically present, their circumstances and mathematical structure are further complicated by the fact that they are a recasting of another work by Bhaskara II that was originally composed in verse, the Karanakutuhala (1183). With almost no accompanying explanation, modern techniques are indispensable for supplying critical information regarding the nature and details of these tables: from establishing basic information, such as the epoch, to identifying and explaining various unidentified functions, such as a mysterious ‘third function’ relating to the equation of the conjunction of Mars, to suggesting numerical links as to how these tables fit into the broader computational nexus of mathematical astronomy traditions of this period. We consider the use of such quantitative techniques in this context, the conclusions they offer, and how they can contribute to the historical discourse of early second millennium astral sciences in India more generally.
