Principal Investigator: Kyoko Amano (Graduate School of Letters, Kyoto University)

The origins of many ancient texts remain a mystery. This project is an attempt to uncover the origins of the ancient Indian literature, the Vedas, through a collaborative approach using linguistics, philology, digital humanities and visual analytics.

This project is the successor to “Chronological and Geographical Features of Ancient Indian Literature Explored by Data-Driven Science” (2020-2021), which was supported by the Supporting Program for Interaction-based Initiative Team Studies (SPIRITS) of Kyoto University as an Interdisciplinary type project, in the priority area of humanities and social sciences.

This website continues to publish the past information (announcements and events) of the SPIRITS project.

This project is an international collaborative research project with Oliver Hellwig, University of Dusseldorf, Germany.
