In brief

  • The Indus script, found on about 4,000 objects, is undeciphered, so all claims about Harappan religion are inference.
  • The Pashupati seal shows a horned figure among animals; calling it 'proto-Shiva' is contested.
  • The cities emptied gradually after c. 1900 BCE amid aridification; there is no evidence of an invasion.
  • No horse, chariot, spoked wheel, iron, monumental temple or royal tomb has been found in mature Harappan levels.

The Indus Valley (Harappan) Civilization flourished as an urban culture c. 2600–1900 BCE across roughly 1.25 million km² of what is now Pakistan and northwest India, and its religion cannot be read, because its script is undeciphered. For seven hundred years it was, on most estimates, the most extensive civilization of its day:[1] planned cities with covered street drains and household bathrooms on a scale unusual anywhere in the Bronze Age,[2] standardized weights accurate across a thousand kilometres, long-distance trade with Mesopotamia, and a writing system on four thousand objects that nobody can read.

That last fact governs this entire chapter. We know the Harappans had a symbolic and probably religious life. They left seals showing horned deities, figures seated in postures, animals in ritual arrangement, and a monumental bathing tank. We cannot say what any of it meant. Everything claimed about Harappan religion is inference from images, and this page’s main job is to show what the images are, what has been claimed about them, and exactly where the claims outrun the evidence.

It also settles two things that can be settled: the cities were not destroyed by invaders, and there were no horses.


Timeline

The Indus Valley Civilization runs from the Early Harappan phase c. 3300 BCE through its mature urban peak c. 2600–1900 BCE to a Late Harappan village phase lasting until c. 1300 BCE.

Where the Harappan cities were

The Harappan cities, among them Mohenjo-daro, Harappa, Rakhigarhi and Dholavira, lie along two river systems: the Indus and its tributaries, and the now-dry Ghaggar-Hakra.

The distribution follows two river systems: the Indus and its tributaries, and the now-dry Ghaggar-Hakra in Haryana and Rajasthan, where a large share of known sites lie. What that dry river was, and when it dried, is one of the most politically loaded questions in Indian archaeology (see the debates below).


The evidence

The Harappans built grid-planned cities with standardized weights and traded with Mesopotamia, but left no palaces or monumental temples, no horse, spoked wheel or iron, and a sign system nobody can read.

Harappan religion: the evidence up close

With the Indus script undeciphered, the Paśupati seal, the Great Bath and the Kalibangan pits remain contested evidence for Harappan religion, while the absence of the horse and of any invasion is secure.

The script, and why it is the wall

Roughly four thousand inscribed objects survive, mostly seals, sealings, and small tablets. The sign inventory is somewhere between 400 and 600 (Iravatham Mahadevan’s 1977 concordance counted 417), which is too many for an alphabet and too few for a purely logographic system like Chinese, suggesting to Asko Parpola and most specialists a logo-syllabic script.[15]​[19] But the inscriptions are catastrophically short: about 4.6 signs on average across the objects in Mahadevan’s concordance, and seventeen at most on any single surface; the “longest” text, twenty-six signs, is only reached by adding together the faces of a moulded multi-sided tablet.[16] There is no bilingual, no Rosetta Stone, and no known descendant language securely attached to it.

The consequences are absolute. We do not know what language the Harappans spoke. We do not know the name of a single Harappan person, city, king, or god. Claims to have deciphered the script appear regularly (more than a hundred have reached print since 1877), and none has convinced the field.[16]​[17] The serious proposals divide by language family: Parpola and Mahadevan argued, on structural and iconographic grounds, for an early Dravidian language, while S. R. Rao read the signs as an early Indo-Aryan script; neither reading can be tested against a bilingual.[19]​[20] Consensus

A measure of how open the problem remains: in January 2025, at a conference marking the centenary of the civilization’s discovery, the Chief Minister of Tamil Nadu announced a one million dollar prize for a successful decipherment, noting that a century of effort had not produced one.[21] The offer is itself evidence: nobody posts a bounty on a solved problem. Consensus

A minority position (Farmer, Sproat & Witzel, 2004) argues the system is not writing at all but a nonlinguistic sign system, like heraldry or tallies. Their evidence: the extreme brevity, the absence of long texts anywhere, the lack of any writing surface for extended documents, and sign frequency distributions unlike known scripts.[16] The counter: sealings are inherently brief everywhere, perishable writing surfaces would not survive, and the signs’ fixed order and positional regularities behave like a logo-syllabic script of the Sumerian type, as Parpola argued in direct reply.[22] In 2009 Rajesh Rao, Mahadevan and colleagues reported in Science that the sequences’ conditional entropy falls within the range of natural languages; Sproat answered that the measure does not separate writing from non-linguistic symbol systems.[23]​[24] Contested

Seal M-304: the “Pashupati” seal

The single most discussed object in South Asian archaeology. A steatite seal from Mohenjo-daro shows a figure seated on a low platform with heels together and knees splayed outward, wearing a tall horned headdress, arms covered in bangles, apparently ithyphallic. Around it: an elephant and a tiger on one side, a rhinoceros and a water buffalo on the other, with two deer or ibexes beneath the seat.[25]

Seal M-304 from Mohenjo-daro, the so-called Paśupati seal. Whether the horned figure is a proto-Śiva, a bull or buffalo deity, or a local version of the Near Eastern Master of Animals is genuinely unsettled; the objections are set out below.unknown Indus Valley Civilization sealmaker from Mohenjodaro archaeological site · Public domain · Wikimedia Commons

John Marshall’s 1931 reading, a prototype of Śiva as Paśupati, “Lord of Beasts”, is based on four correspondences: the yogic posture, the animal lordship, the possible three faces, and the ithyphallic form. It has been repeated for ninety years and appears in most textbooks.[26] Its strongest modern defence is Thomas McEvilley’s: the heels-together squat matches a posture (mūlabandhāsana) that later Indian ascetic literature ties to meditation.[27]

The objections, which are serious:

  • Doris Srinivasan’s critique (1975 onward): the “three faces” are not clearly faces; the headdress is bovine, and the figure may be a bull-deity or a buffalo-man, a widespread Near Eastern and Indian type, not a proto-Śiva.[28]​[29]
  • The Master of Animals motif (a figure flanked by wild beasts) is common across Mesopotamia, Elam and Central Asia in this period. The seal may simply be a local version of a shared regional iconography.[17]
  • The posture is not securely yogic; Parpola compares it with seated bull-figures in Proto-Elamite art, and Geoffrey Samuel cautions that reading meditation into it projects much later practice backwards.[17]​[30]
  • Above all: Rudra in the Rigveda is not a lord of wild animals, not a yogi, and not ithyphallic. The Paśupati identification requires matching the seal to a form of Śiva that is attested only 1,500–2,000 years later. It is a resemblance to a later deity, which is exactly the kind of match that should raise suspicion.[31] Contested

Where this series lands: the seal shows a horned figure of evident religious importance surrounded by wild animals. It may well belong to a stream of imagery that later fed into Śiva. Calling it “proto-Śiva” as established fact is not supportable.

The Great Bath

At Mohenjo-daro, a sunken brick tank roughly 12 × 7 metres and 2.4 metres deep, with steps at both ends, a bitumen waterproof layer, and a drain, set within a building on the citadel mound, surrounded by small rooms. It was excavated in 1926.[18]​[26]​[2]

The argument for ritual use: its prominence and cost; the surrounding cells resembling changing or preparation rooms; the elaborate waterproofing; and the extraordinary attention to water and personal bathing throughout Harappan domestic architecture, which is unusual among Bronze Age civilizations. Kenoyer, who excavated at Harappa for decades, judges that most scholars accept a use in religious purification.[2]

The argument against reading too much in: nothing marks it as sacred: no altar, no imagery, no deposits, no iconography. A civic bath, an elite amenity, or a water-storage facility all remain possible.[18] Contested

The wider point is safer than the specific one: Harappan cities were built around water management and personal cleanliness to a degree no contemporary civilization matched, and the later Indian religious emphasis on ritual purity through bathing has an obvious ancestral candidate here. Speculative on the connection

The Kalibangan “fire altars”

At Kalibangan, a row of seven clay-lined pits on a raised mud-brick platform, each with a clay stele at the centre, containing ash and charcoal; animal bone was found in pits nearby.[32]​[8] S. R. Rao reported similar fire pits at Lothal.[9]

B. B. Lal and others read these as fire altars implying Vedic-style yajña, and therefore Vedic religion inside the Harappan world, which, if right, would collapse the chronology this series uses.[33] The counter-arguments: the pits contain no soma-related apparatus, no offering ladles, and none of the geometrically precise altar-construction that defines Vedic ritual; they may be communal hearths or feasting installations; and Vedic śrauta altars have a specific, well-documented form these do not match.[34]​[3] Contested / Political

The absent horse

There is no securely identified horse bone from any mature Harappan level, no depiction of a horse among thousands of animal images on seals, and no spoked wheel or chariot.[2] Meanwhile the Rigveda is saturated with horses and chariots; two whole hymns (1.162–163) celebrate the sacrificial horse.[35]​[36]

This is one of the strongest arguments that the Rigvedic culture and the mature Harappan culture are not the same thing, and since 2021 it has stopped being an argument from absence. Librado et al. (Nature 2021, 2024) show that the modern domestic horse lineage began its rapid Eurasian expansion only around 2200 BCE.[37]​[38] That makes the domestic horse very unlikely to have reached South Asia during the mature Harappan phase: it had barely begun to spread beyond the steppe. The counter-claim rests chiefly on a 1997 identification by Sándor Bökönyi of horse remains at Surkotada,[39] disputed in detail by Richard Meadow and Ajita Patel, who identified the specimens as onager or half-ass.[13] Consensus on the absence; Contested on Surkotada

How it ended: and how it did not

Mortimer Wheeler, who dug at Harappa and Mohenjo-daro in the 1940s and 1950s, took scattered skeletons found by earlier excavators at Mohenjo-daro in the 1920s, connected them to the Rigveda’s Indra as purandara, “fort-destroyer,” and proposed that Aryan invaders sacked the cities.[40]​[41] This became the standard popular story, and it is wrong.

  • The skeletons are not a massacre. Kenneth Kennedy’s reanalysis showed no battle trauma; the bodies come from different stratigraphic levels spanning centuries; several are ordinary interments.[41]​[42]
  • There is no destruction layer, no burning horizon, no weapons cache, no defensive reorganization at any Harappan city.[2]
  • The pattern is gradual de-urbanization over generations: public buildings falling out of maintenance, drainage failing, populations dispersing east and south into village cultures.[1]​[3]

The current explanation is environmental and economic. The 4.2-kiloyear aridification event weakened the monsoon, and the Ghaggar-Hakra, which Giosan et al. (PNAS 2012) show was monsoon-fed, not glacier-fed, throughout the Holocene[4], declined with it. (The Sutlej and Yamuna were diverted away from that valley, but well before the Harappans: Clift et al. place the Yamuna’s capture in the Pleistocene,[43] and Singh et al. 2017 date the Sutlej’s shift to its present course to about 8,000 years ago, arguing that the abandoned, flood-free palaeochannel is precisely why settlements clustered there.[44] Chatterjee et al. 2019 dissent, finding Himalayan sediment in the Ghaggar until about 4,500 years ago.[45]) Agriculture shifted toward drought-tolerant millets and smaller settlements; and the long-distance trade with Mesopotamia that supported urban elites contracted. Cities need surplus and exchange. Both failed.[1]​[46] Majority

This matters for the whole series. The “Aryan invasion” that popular argument attacks and defends was abandoned by scholarship decades ago. The current migration model (§0) proposes gradual movement into an already de-urbanizing landscape, several centuries after the cities declined. Nobody sacked anything.


What is absent

The Harappan record has no monumental temple, no large cult image, no royal iconography, no unambiguous weapons of war, and no horse, chariot, spoked wheel or iron.

The Harappan absences are as informative as the Rigvedic ones, and they point in a completely different direction:

  • No monumental temple. In seven centuries of city-building, nothing identifiable as a large religious structure.
  • No large-scale cult image, no divine statuary, nothing corresponding to a Mesopotamian ziggurat’s god-house.
  • No royal iconography: no king-lists, no victory reliefs, no named rulers, no royal burials with wealth.
  • No unambiguous weapons of war, no fortification designed against siege, no depictions of battle.[11]​[2]
  • No horse, no chariot, no spoked wheel, no iron.

Set the first four against contemporary Egypt and Mesopotamia and the contrast is stark. Whatever organized Harappan society, it did not advertise itself through god-kings and temples. Whether that reflects a genuinely different politics or simply a different medium of display is open. Contested


Debates

The main debates about the Indus Civilization concern the identity of the Sarasvatī, whether the Harappans were the Vedic people, whether their religion continues into Hinduism, and whether their society was egalitarian.

What was the Sarasvati river?

The Rigveda praises a Sarasvatī as a great river, “Pure in her course from mountains to the ocean” in Griffith’s translation.[47] Many identify it with the Ghaggar-Hakra, along which a large proportion of Harappan sites lie. If the Rigvedic Sarasvatī is a mighty Ghaggar-Hakra, and that river was already declining by c. 2000 BCE, the Rigveda would have to be older than the standard chronology allows, and the Harappans would be Vedic. Chatterjee et al. 2019 support the first step, finding that the Ghaggar carried Himalayan sediment and was perennial until about 4,500 years ago.[33]​[48]​[45]

The counter-case: recent geomorphology (Giosan et al. 2012; Clift et al. 2012) indicates the Ghaggar-Hakra was monsoon-fed rather than glacier-fed for most of the Harappan period, and so never the perennial Himalayan torrent the hymns describe;[4]​[43] the name Sarasvatī corresponds etymologically to Avestan Haraxvaitī, the Helmand in Afghanistan, and may have been transferred eastward with the people; and Rigvedic river praise is formulaic, applied hyperbolically to several rivers.[49] The Rigveda itself also names the Sarasvatī beside two small local streams, the Dṛṣadvatī and Āpayā,[50] and the later Pañcaviṃśa Brāhmaṇa knows Vinaśana, the place where it vanishes into the sand.[51] Contested / Political

Were the Harappans and the Vedic people the same?

Almost certainly not, and the evidence is convergent rather than single-stranded: the Harappans had cities, brick, drainage, seals, writing, and no horses; the Rigvedic people had horses, chariots, no cities, no writing, and no vocabulary for any of the Harappan material world. The Rigveda never describes anything like a Harappan city (no fired brick, no drains, no seals, no standardized weights), which it could hardly have missed.[49] (It does have Indra shattering puras, but those are ramparts and strongholds, not this.)[36] And Rakhigarhi’s genome lacks the steppe component that later populations carry.[6]​[52] The strongest dissent is B. B. Lal’s: the excavator of Kalibangan argued that the Sarasvatī’s place in the hymns and the fire altars make the Harappans and the Rigvedic people one population.[33] Majority

Is there continuity from the Harappans into Hinduism?

Yes, in all likelihood, but through the substrate, not through the Vedas. Pipal veneration, ritual bathing, possible proto-Śiva imagery, the swastika, and animal symbolism all plausibly descend from this world into later popular religion, which then merges with the Vedic stream from Chapter 7 onward. Plausibly, not demonstrably.[17] Majority on some continuity; Contested on every specific item

Was Harappan society egalitarian?

The absence of palaces and royal tombs has produced readings of the Harappans as unusually non-hierarchical, even as a merchant oligarchy or a theocratic collective. Caution: differences in house size, access to wealth goods, and burial provision do exist. Absence of advertised hierarchy is not absence of hierarchy.[11]​[1] Contested

Quick answers

Short answers drawn from the chapter above; the evidence for each is cited there.

Has the Indus script been deciphered?
No. About 4,000 inscribed objects survive, with 400 to 600 signs, fewer than five signs per inscription on average and no more than 17 on any single surface. There is no bilingual text, and more than a hundred claimed decipherments have convinced no one. In January 2025 Tamil Nadu offered a one million dollar prize for a solution. A minority argues the signs are not writing at all.
Is the Pashupati seal an early form of Shiva?
That is contested. John Marshall's 1931 proto-Shiva reading rests on posture, animals, possible three faces and ithyphallic form. Critics note the headdress is bovine, the faces are unclear, the Master of Animals motif is common in Mesopotamia and Elam, and Rigvedic Rudra is neither a yogi nor a lord of wild animals. The seal shows an important horned figure; calling it proto-Shiva as fact is not supportable. Full answer
Why did the Indus Valley Civilization decline?
It declined gradually from about 1900 BCE, not by conquest. The 4.2-kiloyear aridification event weakened the monsoon, the monsoon-fed Ghaggar-Hakra shrank, farming shifted to drought-tolerant millets, and trade with Mesopotamia contracted. There is no destruction layer, and Wheeler's 'massacre' skeletons show no battle trauma and come from different periods. Scholars broadly agree on this picture.
Were there horses in the Indus Valley Civilization?
No securely identified horse bone comes from any mature Harappan level, no seal depicts a horse, and there is no spoked wheel or chariot. The Sinauli vehicles have solid disc wheels and no horse remains. Genetic work by Librado et al. shows the domestic horse only began spreading across Eurasia around 2200 BCE. A claimed horse at Surkotada is disputed as an onager.
Were the Harappans the same people as the Vedic Aryans?
Most scholars say almost certainly not. The Harappans had cities, fired brick, drainage, seals, writing and no horses; the Rigvedic people had horses and chariots, no cities, no writing and no vocabulary for the Harappan material world. The Rakhigarhi genome also lacks the steppe ancestry later populations carry. Continuity into Hinduism likely runs through popular religion, not the Vedas.
Was the Great Bath at Mohenjo-daro used for religious rituals?
Possibly, but it is contested. The waterproofed brick tank, about 12 by 7 metres and 2.4 metres deep, is prominent and costly, with surrounding rooms like changing cells. Yet nothing marks it as sacred: no altar, imagery or deposits. A civic bath or elite amenity remains possible. The safer point is that Harappan cities invested unusually in water and bathing.
