In the collective imagination, the 7 Rivers civilization is often presented as a terrestrial civilization — cities on the plains, irrigated fields, caravan routes. But the archaeological data tell another story: it was also, and perhaps above all for its long-distance trade, a maritime civilization.
Boats engraved on steatite seals. Terracotta figurines representing watercraft. An artificial shipyard at Lothal that is the oldest documented artificial shipyard in the world. Indus goods found in Bahrain, Oman, Iran and as far as Mesopotamia.
The 7 Rivers civilization sailed. And it sailed far.
The seals and figurines: archaeological documentation
Representations of boats in the 7 Rivers civilization are multiple and precise. On certain steatite seals found at Mohenjo-Daro and other sites, watercraft are depicted with a central mast, a sail, and sometimes rowers. These representations, though schematic — like all seal iconography — give valuable information about the type of vessels used.
Terracotta boat figurines — found at several sites including Lothal — show flat-bottomed vessels, suited for river navigation and estuaries. These types of craft could navigate both on the Indus rivers and in the coastal waters of the Gulf of Oman.
The diversity of representations suggests a varied fleet: small boats for river trade between cities, medium-sized vessels for coastal crossings, and probably ocean-going ships for the great expeditions to Mesopotamia and Bahrain.
Lothal: the world’s oldest shipyard
The most spectacular proof of the 7 Rivers civilization’s maritime mastery is found at Lothal, in Gujarat — the southernmost site of the civilization, a few kilometres from the present coast of the Gulf of Khambhat.
Lothal was one of the principal craft production centres of the civilization — notably of carnelian beads, of which thousands were found in the excavations. And beyond its workshops, Lothal possessed something unique in the ancient world: a masonry shipyard.
This structure measures approximately 218 metres long by 37 metres wide. Its walls are in bricks of the same quality as other constructions of the civilization — fired, standardized, carefully laid. A canal linked the structure to the Bhogava river.
Long interpreted as an “artificial dock” by 20th-century archaeologists, this structure has been reexamined in light of recent excavations conducted by Indian archaeologists — and reidentified as a shipyard. This is a conclusion I had myself anticipated in The Civilization of the 7 Rivers after consulting Breton sailors: the structure, built inland and at a distance from open sea, makes no sense as a port. It makes complete sense as a place where boats were built, repaired, and launched into the canal to be guided toward the sea.
This correction is not a detail. It says something important about the nature of the 7 Rivers civilization: it did not merely sail — it built its own vessels, with the same artisanal mastery that produced its standardized bricks, its carnelian beads and its sesame-seed-calibrated weights.
The maritime routes: from the Indus to the Euphrates
The maritime routes of the 7 Rivers civilization are documented by artefacts found at destination sites. Carnelian beads from Lothal in the royal tombs of Ur. Indus seals in Bahrain and Oman. Weights and measures identical to those of the 7 Rivers civilization in Sumerian markets.
These routes followed a relatively fixed itinerary. Ships left the ports of Gujarat and Sindh — Lothal, and probably other less well-documented ports on the Makran coast — crossed the Gulf of Oman hugging the Arabian coast, stopped at Magan (modern Oman) for copper, and at Dilmun (Bahrain) to redistribute goods, before heading up the Persian Gulf to the mouth of the Euphrates.
To complete these journeys of several thousand kilometres, the sailors of the 7 Rivers civilization had to master the seasonal winds — the south-west monsoon in summer, which pushes westward, and the north-east monsoon in winter, which facilitates the return. This knowledge of the winds is itself astronomical knowledge — the sailing seasons correspond to the cycles of the Sun and Moon that the Rig Veda hymns abundantly evoke.
Maritime trade as a vector of peace
What is remarkable about the maritime trade of the 7 Rivers civilization is that it functioned without a war fleet. No military vessels were depicted in the iconography. No Sumerian cuneiform text mentions any conflict with Meluhha — the Sumerian name for the 7 Rivers civilization.
Sumerian tablets describe Meluhha merchants as regular, reliable partners, whose goods were recognized and valued. There were even, at the Sumerian court, “interpreters of Meluhha” — specialists who facilitated commercial negotiations between the two civilizations.
Maritime trade without a navy, without pillage, without servitude imposed on partners — for centuries. This is another manifestation of what I documented in The Civilization of the 7 Rivers: a civilization whose leaders, regularly exposed to the ego-dissolution experience of soma, sought not domination but exchange.
The Rig Veda and the sea
In the hymns of the Rig Veda, the sea — samudra — is omnipresent. It is the final destination of the rivers, the symbol of the Brahman as an ocean of absolute consciousness, the horizon that surpasses everything.
7.95.2 — Alone among rivers, Sarasvatī shows herself brilliant. She goes from the mountains to the ocean.
The creative speech Vāc herself says that her “matrix is in the waters of the ocean.” The ocean is not only a geographical reality for the rishis. It is the most accurate metaphor for the Brahman — immense, impenetrable to ordinary senses, source of all and destination of all.
A maritime civilization that deifies the ocean and sees in it the face of the Brahman maintains a relationship with the sea that goes beyond the merely utilitarian. It sails toward something.
