The 'Agastya battery'
AI-drafted · awaiting admin review
Does a verse in the Agastya Samhita describe an electric cell thousands of years before Volta?
Indian claim not supported by evidenceTechnology & engineering
Indian claim
A passage said to be from the Agastya Samhita describes placing a copper plate, copper sulphate, wet sawdust and amalgamated zinc in a clay pot, which websites and some speakers call an ancient battery ('mitra-varuna shakti').
Evidence for the Indian claim
- The recipe, if built, does make a simple copper–zinc cell; modern rebuilds report about 1 volt.
- The passage has circulated since the early 20th century from a manuscript said to have been found in Ujjain.
Commonly credited to
Alessandro Volta built the first electric battery, the voltaic pile, in 1800.
Evidence for the other claim
- No dated, ancient manuscript of the passage has been published or examined by scholars; the 'Agastya Samhita' title covers several different texts.
- The passage uses ideas such as amalgamated zinc and copper sulphate solution that appear in 19th-century chemistry.
- No ancient Indian text or object shows electricity being used for any purpose.
What historians and scientists say
The battery passage has no verified ancient manuscript and likely reflects modern chemistry. Volta's 1800 pile remains the first documented battery.
