Pashupati Seals of Indus Valley Civilization 

Shiva_Pashupati

  • The Pashupati Seal is a small square-shaped steatite (soft stone) seal discovered from the site of Mohenjo-daro, one of the main cities of the Indus Valley Civilization. It dates back to around 2500–2000 BCE. This seal features a central human-like figure, sitting in a meditative posture, surrounded by various animals.
  • The word ‘Pashupati’ is derived from Sanskrit – ‘Pashu’ means animal, and ‘Pati’ means lord or master. So, ‘Pashupati’ translates to ‘Lord of the Animals’. In Hindu tradition, this title is often used for Lord Shiva, who is seen as the protector of all creatures and nature.
  • In 1928–29, archaeologist Sir John Marshall was the first to interpret this figure as an early representation of Shiva, due to its posture, horned headgear, and association with animals. He compared it to Shiva’s yogic and meditative image known from later Hindu scriptures.

Features of the Pashupati Seals of Indus Valley Civilization 

Central Figure (Human-like)

  • A man-like figure is sitting cross-legged in a posture similar to Mulabandhasana or early yogic pose.
  • He wears a horned headdress, which may represent divine or royal power.
  • Some scholars argue the figure is three-faced, but due to erosion, it’s hard to confirm.
  • The hands rest on the knees, giving the impression of deep meditation or spiritual focus.

Animals Around the Figure

  • On either side, four wild animals are carved:
    • Elephant (top left)
    • Tiger (top right)
    • Rhinoceros (bottom left)
    • Buffalo (bottom right)
  • Below the main figure, two deer or goats are shown facing the center.

Indus Script

  • There is a short line of symbols from the Indus script above the figure.
  • This script is still undeciphered, so we don’t know the exact meaning.

The Unicorn-Bull Seal (Mohenjo-daro)

  • Shows a one-horned animal with a stylized hump and a trough in front.
  • Accompanied by 4–6 script signs above.
  • Found in large numbers—suggesting a universal administrative or economic symbol.

The Elephant Seal (Lothal)

  • Shows a well-decorated elephant with visible anklets and an arched body.
  • Likely symbolizes power, wisdom, or trade authority.
  • May have been associated with merchant identity or regional symbols.

Harappan Script 

Contains 400+ symbols, still undeciphered despite intense scholarly efforts. Always placed before the main image, indicating its importance. Likely used for naming, categorization, or certification—maybe even an early writing system meant for elite or commercial use. The uniformity suggests a regulated writing system, though its exact linguistic basis remains unknown.

Script on Seals of Indus Valley Civilization

While the imagery on Harappan Seals of Indus Valley Civilization is immediately visible, the inscriptions etched above the motifs remain one of the most enduring mysteries of the ancient world.

  • Length and Placement: Most inscriptions carry 5–6 signs, placed in a horizontal row above the main image. In rare cases, the number may go up to 26.
  • Reading Order Ambiguity: Scholars are still debating whether the script is left-to-right, right-to-left, or even boustrophedon (zigzag).
  • Lack of Rosetta Stone: No bilingual or multilingual inscription has been found. This makes decipherment extremely difficult.
  • Functional Use: Until deciphered, these short texts are assumed to act like guild marks, family identifiers, or ownership tags, rather than a full writing system.
  • Current Research: Frequency analysis and contextual comparison are the primary tools scholars are using to break this code. But for now, these remain cryptic messages from the ancient world, guarding secrets of trade, religion, and administration.

Interpretations and Debates on Seals of Indus Valley Civilization

Despite decades of excavation and analysis, scholars still debate the exact function and symbolism of these Seals of Indus Valley. Some of the main interpretations include:

    • It may have symbolized a clan emblem, a powerful deity, or even a trade guild.
    • The standardization across cities implies centralized importance.
  • Proto-Shiva or Pashupati Hypothesis

    • The famous Pashupati Seal shows a horned figure seated in yogic posture, surrounded by animals.
    • Some scholars interpret this as a proto-form of Lord Shiva, known as Pashupati (Lord of Animals).
    • The horned headgear and meditative pose support the religious archetype, but critics call this speculative due to lack of corroborative evidence.
  • Script as a Functional Token

    • Some experts believe that the script and image were symbolic rather than linguistic more like a logo or trademark.
    • In the absence of long-form writing, Seals of Indus Valley Civilization might have simply acted as identifiers in a bureaucratic or trading context.
  • Ritual Talisman Hypothesis

    • Seals of Indus Valley Civilization with composite or ambiguous figures may have served as spiritual or ritual talismans.
    • These could have been used to invoke blessings, ward off evil, or carry religious messages.
  • Guild and Power Markers

    • Seals of Indus Valley Civilization might have worked as trade permits, guild badges, or certificates of authenticity in long-distance transactions.
    • Their presence in faraway lands like Mesopotamia supports this theory.
