Abstract :
The Indus Valley Civilization, the largest Bronze Age civilization, laid the foundation of Indian culture and genetics. Its script, dating back to 4000 BCE, remains undeciphered despite numerous attempts. Our study approaches the script as a cryptogram, validated using Claude Shannon’s methods, with a Sanskrit dictionary aiding decipherment.
Analysis reveals the script has ~100 signs, aligning with proto-abugida characteristics, and its grammar corresponds to post-Vedic Sanskrit. We deciphered over 4300 inscriptions, identifying 74 primary allographs and translating 500+ inscriptions. Findings show Brahmi glyphs evolved from Indus signs, linking the Indus Valley to classical Indian civilization and offering insights into early history and culture.
