L. van der Waerden and David Pingree. According to Pingree, the Paitāmahasiddhānta is the “basic text” of the school of Brāhmapakṣa, which belongs to the earliest stage of the “Greek Period” in Indian astronomy since ca. 400 CE; furthermore, this work was known to Āryabhaṭa and was the source of Brahmagupta’s Brāhmasphuṭasiddhānta. Van der Waerden, on the other hand, refuted Pingree’s claims on multiple grounds, both in terms of the philological issues involved and its mathematical content. What remains unexplored, as the crux of the problem, was the critical text of the Paitāmahasiddhānta itself, which Pingree never published or commented on, much less questioned by others. This papers attempts to delineate the problem by revisiting all the extant primary sources and to thereby evaluate Pingree’s reconstruction of the textual lineage of the Paitamāhasiddhānta. In addition, this paper provides a critical edition and translation of the two hitherto unedited opening astrological chapters of the Paitamāhasiddhānta.
