An international team of researchers has announced the successful decipherment of a cache of 9th-century Grantha script manuscripts using advanced AI-driven optical character recognition. The documents, found in a temple archive in Tamil Nadu, detail lost Sanskrit treatises on hydro-mechanical engineering, including blueprints for automated pressure-regulated valves used in the construction of complex step-wells.
The manuscripts describe the use of counterweights and siphons to maintain constant water levels during drought periods. This discovery provides the first written evidence for the high level of fluid dynamics expertise required to build the monumental hydraulic architecture seen across the Indian subcontinent during the early medieval period.
