Indian planetary tables can be classified into several distinct types with respect to their underlying mathematicbal structure. One of these, the so-called “cyclic” scheme was inspired by goal-year periods introduced via Islamic channels no later than the early seventeenth century. The first set of such cyclic planetary tables is the Jagadbhý½aṇa of Haridatta, composed in Mewar, R×jasthan with an epoch of 31 March 1638. This substantial work, spreading over more than 100 folia in some manuscripts, computes the true longitudes of the planets in a manner similar to those in the Babylonian goal-year texts, Ptolemy, and al- Zarq×l÷. We will consider the inspiration from these earlier sources and how they are incorporated into a distinctly Indian context, with respect to mathematical structure, astronomical foundation, and layout and arrangement of the data in the tabular format.
