The hypothesis that the Harappan language was Proto-Dravidian has been influential since the discovery of the civilization. The corpus contains both supporting evidence and rigorous methodological critiques.

The Dravido-Harappan Hypothesis

Proponents

  • Asko Parpola: Leading advocate of a Dravidian decipherment of the Indus script
  • Iravatham Mahadevan: Argued for Dravidian readings of Indus signs
  • Many South Indian scholars: See the Harappan civilization as an ancestral Dravidian culture

Arguments For

  • Geographic overlap between Harappan and early Dravidian areas
  • Retention of Brahui (a Dravidian language) in Balochistan, near Harappan sites
  • Certain Indus signs interpreted with Dravidian etymologies
  • Agricultural vocabulary in Dravidian languages suggesting ancient farming traditions

Danino’s Critique

Michel Danino’s paper “A Dravido-Harappan Connection? The Issue of Methodology” provides a rigorous critique:

  • Colonial origins: The Dravidian-Aryan dichotomy was invented by 19th-century European scholars, imposing racial meanings on linguistic terms
  • Script ≠ Language: Finding Indus-like signs in South India proves nothing about the underlying language — script can be adopted across language families
  • Archaeological gaps: No Harappan artifacts south of the Vindhyas; Harappans could not have “reverted” from Bronze Age urbanism to Neolithic and migrated
  • The Sembiyan-Kandiyur celt: An inscribed stone axe claimed as proof of Indus script in Tamil Nadu lacks archaeological context; the signs may not be Indus at all
  • Brahui: Recent linguistic studies suggest Brahui may be a relatively late introduction to Balochistan, not a remnant of Harappan Dravidian

Vedic-Dravidian Linguistic Interactions

The corpus documents the complex interactions between Vedic Sanskrit and Dravidian languages:

  • Loanwords: Some Dravidian loanwords exist in Vedic (though fewer than expected under AIT)
  • Structural influence: Retroflex consonants may reflect Dravidian influence on Sanskrit (or vice versa, or independent development)
  • Tamil and Sanskrit: The relationship between Tamil and Sanskrit is one of mutual enrichment rather than opposition

Early Tamil Culture

  • Vedic Roots of Early Tamil Culture: Evidence of Vedic influences in ancient Tamil society
  • Tamil Heroes: Sangam literature depicting a heroic age
  • Syncretism: The integration of Vedic and Tamil religious traditions

Other Language Family Hypotheses

Austroasiatic (Munda)

  • Some scholars propose the Indus language was Munda
  • Agricultural vocabulary in Munda languages supports ancient roots
  • Genetic studies show Munda speakers have distinct ancestry

Other Theories

  • The Indus language may have been unrelated to any known family
  • It could have been a trade pidgin with elements from multiple families
  • The Language of ISC (S. Kalyanaraman) argues for a Vedic reading
