During the project, (1) the cosmographic section of the Somasiddhānta was reading studied in a seminar. (2) The Sanskrit text of cosmographic section of the Romakasiddhānta, which has never been edited or published, was edited based on three manuscripts. (3) The question of the shape of the earth according to the Purāṇas was taken up, and the arguments of Jñānarāja (ca. 1500 CE) was studied with a view to determine whether his interpretation of the Purāṇic statements he cited was in line with the texts themselves and the traditional commentaries. (4) Since the astronomers often state that followers of the Purāṇas compare the earth to a mirror, a study was conducted on what a comparison to a mirror meant in ancient and medieval India.
A brief overview of the results are as follows:
For (1), while the Somasiddhānta turned out not to directly engage with the attempt to create a synthesis of different cosmologies, the text is of interest since it has a complex relationship to the text of the Sūryasiddhānta. For (2), the Romakasiddhānta also does not engage with the attempt to create a synthesis of different cosmologies, but its cosmological section is of great interest. Much more than other cosmological sections in astronomical works, it gives a rich detail of (mythological) terrestrial geography, for which reason an edition and study of the section is worth publishing. For (3), an article on this has been submitted for publication already. The conclusion is that Jñānarāja misinterprets Purāṇic passages when he attempts to show that there is support for a spherical earth in the Purāṇas. For (4), it was seen that comparison of an object to a mirror does not necessarily mean that the object is flat. It can also mean that the object is round or that it is smooth/glossy.
Regular seminars were held during the project during which the different aspects of the project were discussed in a group setting. Furthermore, a seminar was held in May 2019, which drew participants from the USA, Japan, and New Zealand.
Overall, the activities of the project has increased our understanding of the interactions between the Siddhāntic and Purāṇic traditions. Furthermore, the project opened up for greater collaboration between researchers. For example, I am now planning regular Sanskrit reading sessions on the topics of the project with two researchers in USA, one of which I am also collaborating with on a topic related to the project.
