Why in the news

Cryptographer Yajnadevam (Bharath Rao) announced that he had deciphered the Indus Valley script, a claim that, if it survives review, could reshape views on the Indus Valley Civilization (IVC).

Key facts

  • Method: cryptographic analysis built on Claude Shannon’s information theory, studying symbol frequency and position.
  • Core idea: with enough coded messages read, only one correct solution emerges.
  • Conclusion: the script records Sanskrit.
  • He links the script to Brahmi, citing look-alike symbols and inscriptions that mix both.
  • Earlier efforts failed because symbol meanings shifted in longer texts and no bilingual inscription (like the Rosetta Stone) exists.

Why Sanskrit, according to Rao

Observation in the scriptReasoning
Tripled symbolsAbsent in agglutinative tongues such as Dravidian or Sumerian, present in Vedic Sanskrit
Complex compound wordsResembles Sanskrit, unlike agglutinative languages
Flexible word orderMatches Sanskrit grammar, not rigid prefix-suffix systems
Brahmi resemblanceSuggests Brahmi grew out of the Indus script, implying an unbroken tradition

Claimed implications

  • The Aryan migration view places Sanskrit’s arrival around 1,500 BCE; a Sanskrit Indus script from about 4,000 BCE would contradict that.
  • It would weaken the idea that Sanskrit was brought by invaders and the claim that the IVC was Dravidian-speaking, and so the north-south divide argument.
  • Inscriptions mentioning the ocean as ‘home’ fit the IVC’s wide trade links, especially with Mesopotamia.
  • References to deities, rituals and daily life hint at a developed spiritual and social order, possibly tied to later Hindu traditions.

Concerns

  • No other cryptographer or epigraphist has confirmed the result.
  • The script is still largely undeciphered and no translation is universally accepted; the method must be tested on many inscriptions.
  • Mainstream scholars say language continuity across thousands of years is uncommon.

Exam angle

  • Claimant: Yajnadevam (Bharath Rao); theory base: Shannon’s information theory.
  • Indus script is still officially undeciphered; this claim needs peer review.
  • Agglutinative examples given: Dravidian and Sumerian.

Test yourself

1. Whose information theory did cryptographer Yajnadevam use to attempt decipherment of the Indus Valley script?

His method rests on Claude Shannon's information theory.

2. Which language does Yajnadevam claim the Indus script records?

He argues tripled symbols, compounds and flexible word order indicate Sanskrit.

3. According to the notes, why did earlier attempts at decipherment struggle?

Both inconsistent meanings in long texts and the lack of a bilingual text were cited.
