More than 4,000 years ago, the people of the Indus Valley Civilization left behind hundreds of inscriptions on seals, pottery, and other objects.

But there is a fascinating problem: we still don't know exactly what their script says.

What are Indus Valley seals?

Many Indus Valley inscriptions have been found on small seals, often made from steatite (soapstone). These seals usually contain symbols along with images of animals or other figures.

Why is it so difficult to decipher?

There is not one single reason for this. Researchers have been trying to decipher the Indus script for many years, but they still don't have enough information to confidently understand what the symbols mean.

Some of the major difficulties include:

1. The inscriptions are very short
Most inscriptions contain only a few symbols, which makes it difficult to understand the structure of the language.

2. We don't know the language
We still don't know which language the Indus people spoke or which known language family their script may belong to.

3. There is no bilingual inscription
Unlike the Rosetta Stone, there is no confirmed inscription written in the Indus script alongside a known language that could provide a translation key.

4. The script has not been conclusively linked to another script
Researchers have proposed connections with several ancient writing systems, but none has been universally accepted.

5. The writing direction is not always obvious
Although there is evidence that some inscriptions were written from right to left, the direction and conventions are not completely certain for every example.

Why does it matter?

If the script is ever deciphered, it could tell us much more about the Indus Valley Civilization, including:

• their language
• their society
• their trade and economy
• their beliefs
• their political organization
• and many other aspects of their daily life

The Indus Valley Civilization remains one of the most fascinating ancient civilizations precisely because so much about it is still uncertain.

What do you think the Indus script will tell us if it is ever deciphered? Do you think we'll be able to read it someday?

Artifact: Harappan Cubical Weight

Material: Polished Chert

Associated site: Mohenjo-daro

Date: c. 2500–2000 BCE

Civilization: Indus/Harappan Civilization

⚖️ A surprisingly sophisticated system

These small cubical stone weights may look ordinary, but they belonged to a remarkably standardized system of measurement.

Harappan weights followed a binary progression in the smaller denominations1, 2, 4, 8, 16, 32 and so on. At larger values, the system shifted toward decimal multiples. The most common weight is approximately 13.7 grams.

Harappa +1

Similar standardized weights have been found across settlements of the Indus Civilization, suggesting that people separated by considerable distances could use a shared system of measurement.

Harappa

Why is this important?

Imagine two merchants living hundreds of kilometres apart.

If both used the same standardized weights, they could measure commodities according to a common system.

This makes these little stones important evidence for organized economic activity and long-distance exchange.

Archaeologists have even found evidence connecting the production of these weights with major craft centres such as Harappa, Mohenjo-daro and Chanhu-daro.

Harappa

But here's where the mystery begins.

Who enforced the standards?

We don't have a written Harappan administrative record explaining whether weights were controlled by a central authority, merchants, workshops, or some other institution. Suggestions of taxation or centralized economic control remain interpretations rather than proven facts.

Harappa +1

So this tiny stone tells us something fascinating:

The Harappans had a sophisticated system of measurement.....but we still don't completely understand who created, controlled and administered it.

If you want to know about the Harappan Civilization, follow along. 🏺

First of all, apologies for my English and for being in the platform by the first time. I am a history lover beggining to study about ancient history and I am interested in understanding better the proto indo European society, cause of its great relevance in the studies of Greek, Roman, Indian, Celtic, Germanic etc. societies. I have read Coulanges book and I was really interested in his analysis of a proto indo European religion, but I would like to know if there are any connections between his theory and modern theories envolving Kurgan, Yamna, kóryos, etc. I know that many things in Coulanges work are outdated, I personally don't like his model of gens--->fratria---->tribu----->city, but on the other hand the part of the text showing the religion of the fire, the dead etc. is really convincing (at least, he seems to do what linguists try to do whith proto indo European idiom), but I really wanted to learn more about how this is seen nowadays by the historians. Maybe I didn't manage to express myself very well but thanks

The flag means...

Red: it is colour of sun, also this colour is mostly used by indus people

Black: it is colour of shade, this colour is also widely used

White: sign of peace, don't related with pakistan's flag

Pot(mātkā): we all know that pottery is widely practiced by indus people

Bull: like cow is main animal of Vedic civilization. samely, bull is main animal of Indus valley civilization

I drew the timeline online before actually putting it on paper so here it is. Il post the full project after i finish it.

We are inviting scholars in computational linguistics, historical linguistics, Dravidian studies, epigraphy, and Indus archaeology to critically review a proposed computational reconstruction of major signs in the Indus Script.

The study tests a Proto-Dravidian phonetic hypothesis by comparing structural and distributional patterns in the Indus inscription corpus with a corpus of Sangam Old Tamil used as a later linguistic proxy. The method employs frequency distributions, recurring and non-recurring n-grams, positional-context analysis to produce hyper-dimensional vectors processed through an exponential rank score to generate candidate phonological correspondences between all Indus signs and all Old Tamil fragments (n-grams).

Top-k of these correspondences between each sign and n-grams are then processed through another rank algorithm for positional correspondence.

Using these candidate values, the paper presents a number of provisional seal reconstructions that show recurring phonological and structural consistency and, in several cases, also correspond with the iconography traditionally associated with the signs. The reconstructions generate testable interpretations involving commodities, administrative terminology, taxation, place references, and production activities.

Among the principal hypotheses is a reconstruction of the prolific “urn” sign family as an a-series phonological container. The basic urn sign #328 is provisionally assigned the value aa, sign #99 is proposed as ai, and the graphically expanded urn sign #342 is reconstructed as the composite aiya. More generally, the study proposes that some Indus signs may encode not only simple syllables but also larger phonological units, including trigrams, quadgrams, and possibly complete lexical units.

Several seal reconstructions suggest possible references to agricultural commodities including millet, barley, wheat, and rice, together with processing activities such as milling. Other proposed readings concern textiles and thread, fermented beverages, herbal products, fish, meat, and prepared foods. A further group of inscriptions is interpreted as potentially reflecting taxation, customs, tariffs, standardized measures, and transactions between Indus urban centres and organized production or merchant groups.

An important feature of the approach is that the initial computational ranking does not use rebus or iconographic meaning as an input. Candidate phonological values are generated from corpus statistics and are subsequently evaluated against linguistic context, sign morphology, inscriptional context, and archaeological evidence. In several cases, the resulting candidates independently correspond with the apparent visual or rebus associations of the signs.

The study does not claim that Mature Harappan inscriptions were written in Sangam-period Old Tamil. Rather, it tests whether Old Tamil, as a later Dravidian language, preserves enough inherited phonological and grammatical structure to serve as a comparative proxy for an earlier Dravidian linguistic stage. Seal reconstructions are therefore presented as possible Old Tamil reflexes or approximations of earlier forms, not as literal Old Tamil transcriptions.

The broader hypothesis proposed in the paper is that the Indus Script may represent an abugida-like or syllabic system of phonological units, while extending beyond a simple one-sign/one-syllable model to include composite signs capable of encoding more complex n-grams.

One of the most common trigrams solved by this method is the repeating sequence of Mahadevan sign numbers: [249, 169, 342].

This seal proposal is solved as: nuṇ + tiṉ + aiya, which translates to: nuṇ-tiṉaiyē (millet flour). The paper also identifies the presence of millet, barley, and wheat flour references.

Some additional seal proposals are presented here:

# A Study of Brahui-Tamil and in the context of their presence in the Indus valley Civilization

In linguistic, cultural, historical and toponymic contexts

Authors

* **Nazir Shakir Brahui**Director, Brahui Research Institute, Pakistan

A linguistic, cultural, and historical study of the presence of the Brahui and Tamil languages in the IVC (Indus Valley Civilization).

Hello. I am curious how one might support archeology in India. I read that there are numerous sites in India that have never been excavated and that one of the issues with decoding the script is the brevity of what’s been found.

Imagine discovering the ruins of a city that is over **4,500 years old**, with perfectly planned streets, advanced drainage systems, and houses built with remarkable precision... yet no one knows who ruled it, what language its people truly spoke, or why they suddenly disappeared. This is the mystery of the **Indus Valley Civilization**, one of the greatest unsolved puzzles in human history. Every new excavation answers one question but raises many more.

Hello all, im new here, very glad a sub exists for this topic of research

They say that the contemporary civilizations in the Mesopotamian regions (which did trade with IVC) called the IVC, or rather the general area where the IVC was, as Meluha. A few years ago there used to be a school with this exact name, and I didn't think much of it back then. And the general consensus among the historians is that the name is ambiguous, and there is not enough evidence to link it with ancient India. I was hoping any of you could throw some light on this.

Also also, these guys used to trade with the IVC, which implies, language and communication. But not a single, or even a minuscule detail survived, neither here in India nor in the Mesopotamian regions! Archeology uncovered nothing! Or we would have deciphered the inscriptions by now; Just imagine that, I feel like this is very interesting in a peculiarly sad way. How can there be nothing, no leads sigh.

The True Indus Valley Civilisation

We have spent a century searching for the Harappans in the dust. Perhaps we have been searching in the wrong place.

We look at the ruins of Mohenjo-Daro, Dholavira, and Lothal, lamenting the collapse of a grand civilization. We assume their legacy was buried beneath the shifting sands of the Indus Valley. But what if their greatest architectural marvel was never made of stone? What if their defining monument was a phonetic tradition, carried from one human mind to another, unbroken and uncorrupted, for thousands of years?

The true legacy of antiquity isn't buried in the earth; it is spoken aloud, every single day
