Using advanced multispectral imaging and AI-driven script reconstruction, researchers in Kanchipuram have translated a series of 5th-century terracotta tablets. The text outlines a previously unknown 'Philosophy of Sound' (Sabda-Darsana), which argues that sound is the foundational substance of the material universe. This early linguistic philosophy predates the famous works of Bhartrihari by several decades.
The tablets contain debates between various local philosophical schools on whether words have an inherent, eternal relationship with their meanings. This discovery provides crucial evidence for the intellectual vibrancy of 5th-century Kanchipuram as a hub for both linguistic and metaphysical inquiry, challenging the idea that such debates were centralized solely in the northern universities of Nalanda or Takshashila.
