The Indus Code, Pg17

Key Highlights:

• The Tamil Nadu government announced a $1 million reward in January 2025 for deciphering the 4,000-year-old Indus script.
• Computer scientist Rajesh P N Rao is a prominent figure in the global race to decode the script, receiving numerous claims.
• The decipherment efforts have evolved from traditional linguistic and archaeological methods to include Artificial Intelligence (AI) and computational approaches.
• The Indus script remains one of history's greatest uncracked codes since the discovery of the Indus Civilisation in 1924.

Detailed Insights:

• The Tamil Nadu government's reward announcement followed a study by its Archaeology Department noting similarities between Indus signs and graffiti marks found in the state.
• Early decipherment efforts were influenced by prevailing archaeological theories, such as the Aryan migration theory, which sought to identify the language of indigenous Indian people.
• Researchers like Nisha Yadav and Mayank Vahiya at the Tata Institute of Fundamental Research (TIFR) used statistical analysis to find patterns in Indus signs, comparing them to known languages and non-linguistic systems.
• Their findings suggest the Indus script likely encoded language, even if the specific language remains unknown.
• Bahata Ansumali Mukhopadhyay, another researcher, concluded that the script does not phonetically spell words and was primarily used for commercial transactions.
• Bryan Wells, a Canadian epigrapher, dedicated decades to building a comprehensive computer-based database of Indus script signs, highlighting the need for computational tools due to the vast amount of data.
• Challenges to decipherment include the lack of comparable bilingual inscriptions, the inability to assign phonetic values without knowing the language, and the limited textual evidence with short inscriptions.
• Current theories about the Indus script include connections to Brahmi script, Sanskrit, and Dravidian languages, while some argue it is not a language at all but rather a system of non-linguistic symbols.

Key Concepts Involved:

• Indus Civilisation: An ancient Bronze Age civilization in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE.
• Indus script: A corpus of symbols produced by the Indus Civilisation that remains undeciphered.
• Artificial Intelligence (AI): The simulation of human intelligence processes by machines, especially computer systems, used here for pattern recognition in the script.
• Brahmi script: One of the oldest writing systems of South Asia, from which most modern Indian scripts are derived.
• Dravidian languages: A family of languages spoken by about 250 million people, mainly in South India and parts of Sri Lanka.
• Rebus principle: A linguistic principle where a pictogram represents a word for the object depicted or any word that sounds similar.
