Made visible · the readable record
The Indus script is undeciphered — the cities cannot yet speak for themselves. But their trading partners in Mesopotamia could write, and they wrote about the Indus constantly: its ships, its goods, its resident merchants, and the professional they employed to translate its language. To read the Indus, for now, we read what Sumer said about it.
a distant maritime country to the east
In Mesopotamian cuneiform, three trading partners lay out along the sea route east: Dilmun (Bahrain and Failaka), Magan (the Oman peninsula and the Iran/Makran coast), and — furthest out — Meluhha, which scholars identify as the Greater Indus Valley. For roughly five centuries in the third millennium BCE, Sumerian and Akkadian scribes recorded a steady traffic with this eastern land: its ships, its cargo, and a community of its people living in Mesopotamia itself.

how the Indus was dated by Mesopotamia
The connection is not a guess from a single tablet. Indus seals were found at Susa, Ur and other Mesopotamian sites — and in a striking historical irony, it was these seals, recognised as stylistically matching the ones at Mohenjo-daro and Harappa, that gave archaeologists their first chronological estimate for the age of the Indus Civilization itself. The Indus world's date was fixed, at first, by where its objects showed up in someone else's ruins. Etched carnelian beads, standardised weights, and Indus-style seals appear across the Gulf and into Mesopotamia — a trail of Indus goods heading west.

a professional interpreter of the Meluhhan language
This is the detail that matters most, because it is a fact about language from a civilization whose language we cannot read. Mesopotamian records attest a professional interpreter of the Meluhhan tongue — locals needed a translator to understand the Indus people. There was a Meluhhan community resident in Mesopotamia; over time it acculturated, and its members came to speak local languages. But early on, the Meluhhans spoke their own language, distinct enough to require a paid interpreter.
A Sumerian scribe recording "interpreter of Meluhha" is documenting, from the outside, that the Indus people spoke a distinct language of their own — not Sumerian, not Akkadian, not a dialect of anything in Mesopotamia. We still cannot read that language. But we know it existed, was spoken by traders in a foreign city, and needed translation — because a foreign bureaucracy wrote the word for the person who did the translating. attested · external record

the Gulf as a cosmopolitan highway
The third-millennium Gulf was a cosmopolitan commercial highway. Traders from Mesopotamia, Dilmun, Magan (Oman), Meluhha (Indus) and Marhashi (the Halil Rud in southeast Iran) all interacted along it, in what one study calls a "pervasive process of cultural hybridization." Indus iconography turns up on seals across Iran and the Gulf; a Harappan colony sat at Shortughai in Afghanistan, near the lapis-lazuli mines, working the blue stone for export. This was not one empire dominating others — it was a network of trading polities, exchanging carnelian, lapis, copper, timber, textiles, pearls and worked stone across thousands of kilometres of sea and caravan route.

what the Indus objects were actually for
Even without reading the script, the function of the Indus seals is becoming legible from their archaeological context. A recent structural analysis argues the inscribed stamp-seals were instruments of administration — taxation, trade and craft licensing, commodity control, access control. Seals cluster near city gates and workshops, alongside standardised weights; sealings closed storage-chamber locks; inscribed pendants at Kanmer may have been gate-passes. The Indus script, on this reading, did not record poems or kings' names — it ran a trade bureaucracy, a system of guilds and governing bodies standardising commerce across settlements. A civilization organised around trade, administered in a script built for it.

Mesopotamia named Meluhha, described its ships, listed its exports, employed its interpreters and housed its residents. We have thousands of lines about them.
We have not one word from them. The Indus script is undeciphered, its inscriptions average about five signs, and there is no bilingual. There is no Indus text naming Ur, Akkad, Dilmun, or anywhere at all.
One side of a five-hundred-year relationship is fully audible. The other is a set of objects.
This is the single clearest case of what preservation asymmetry does to history. The Indus was, by area, the largest urban civilisation of its era. It is known to the written record only as somebody else's trading partner — identified, priced, and named in a foreign language.
The detail that should be more famous than it is
| c. 2350–1800 BCE | Meluhha = the east. The maritime land beyond Magan, source of carnelian. References cluster in the Akkadian and Ur III periods |
| after c. 1800 BCE | References fade, in step with Indus deurbanisation. Dilmun takes over as the Gulf entrepôt |
| 1st millennium BCE | Meluhha = Nubia. In Neo-Assyrian texts the name is applied to Kush and the Egyptian south — a completely different continent |
A name for a specific people detached from them entirely and was reassigned, roughly a thousand years later, to a different population two thousand miles away.
It is the same operation catalogued elsewhere on this platform, in its purest form. Names record the namer's frame of reference, not the named. "Meluhha" meant the far southern trading country, and when the original one stopped existing, the label was reattached to whichever land now occupied that slot.
And it is why the identification of Bronze Age Meluhha with the Indus, though widely accepted, is an inference — from chronology, from geography, from carnelian and from the seals. It is not stated by anyone in antiquity, because the only people who could have confirmed it left no readable text.
Parpola: Dravidian mel-akam, "high country" or "highland" — attractive, and dependent on the Indus being Dravidian-speaking, which is unproven.
The mleccha link: Sanskrit mleccha, "one who speaks indistinctly," resembles Meluḫḫa. But ḫḫ → cch is not a sound law. The honest reading is that both are independent attempts by two writing systems to render one foreign name neither could spell — cuneiform ḫ being precisely the slot used for foreign gutturals.
Neither proposal is refuted. Neither is established. And a decipherment would settle both in an afternoon.
