How We Know: Inscriptions, Manuscripts and Archaeology

For most of the last two thousand years, ancient India could not be read. Across the subcontinent stood pillars and rock faces covered in neat rows of letters, and no living person knew what a single one of them said. Emperors had carved their decrees into stone to last forever, and forever had arrived, and the stone had gone silent.

Then, in 1837, in Calcutta, a clerk at the mint broke the silence with a single word.

His name was James Prinsep. He was the assay-master of the East India Company’s mint and the secretary of the Asiatic Society of Bengal, and he had been worrying at the old script the way you worry a knot. His way in was small. On the railings of the great stupa at Sanchi, short inscriptions kept ending in the same two characters. Prinsep guessed they were donation records, and that the repeated ending was the word for the act itself: dānam, the gift. He was right. From that one word the whole alphabet began to unlock.

The gift of so-and-so. The gift of so-and-so. The same two signs, again and again, until they gave up their sound.

This is where the real history of Sanatana Dharma begins, in the sense of history that can be dated and checked. Behind every confident year in this story stands a piece of physical evidence and a method for reading it. Knowing those methods is the difference between taking the past on faith and actually knowing it, and it is the best defence against two opposite errors: swallowing every traditional date whole, and dismissing the deep past as unknowable. We know a great deal. We know it unevenly. The honesty is in saying which is which.

The stones that learned to speak

Prinsep did not work alone, and good history credits the chain. The year before, the scholar Christian Lassen had fixed some Brahmi letters using bilingual coins of the Indo-Greek kings, Greek on one face and Indian script on the other, an accidental Rosetta Stone struck in silver. Prinsep finished the work. And the reward was enormous, because Brāhmī is the ancestor of nearly every script later used in India. Crack it once and the whole inscribed record opens at the same moment.

What opened first was Ashoka. The edicts of the Mauryan emperor, carved around 250 to 232 BCE on rocks and pillars from Afghanistan to the south, turned out to be the words of a living ruler who called himself Devanampiya Piyadasi, Beloved of the Gods. Using a king-list preserved in Sri Lanka, Prinsep identified him as Ashoka. A man who had been a name in legend became a voice with a date.

Inscriptions are the historian’s firmest ground, because they are contemporary with the events they record and often carry their own date. The Allahabad pillar holds the eulogy of the Gupta emperor Samudragupta, composed by his court poet Harisena, cut into the very same shaft that already bore an edict of Ashoka, one stone wearing six centuries like rings on a tree. The Aihole inscription dates a Chalukya temple to 634 or 635 CE in polished Sanskrit verse. Best of all are the copper-plate land grants, engraved with a date, a donor king, a recipient, the boundaries of the gifted land, and a royal genealogy, documents almost designed for the future historian.

And then there is the silence that proves the rule. The Indus script, older than all of these, has never been read. That is the whole reason its religion is guesswork. Brahmi turned mute stone into testimony. The Indus seals still keep their mouths shut.

The texts that had to be copied to survive

Manuscripts are the second witness, and they come wrapped in a paradox: India’s oldest texts survive in its youngest copies.

The reason is physical. Indian manuscripts were written on palm leaf and birch bark, organic things, and the climate is merciless to them. Heat, damp and insects destroy a manuscript within a few centuries. A text survived only if someone copied it, and then copied the copy, generation after generation, a relay race run for thousands of years in which the baton was constantly remade. Most surviving Indian manuscripts are therefore only a few hundred years old, even when the work they carry is ancient.

The Vedas escaped the relay by refusing to run it. They were held in memory, recited by methods so redundant, the same verse chanted forwards, backwards, in interlocking permutations, that error was almost impossible, and they were preserved this way for centuries before anyone wrote them down. For the Vedas the living chant, not any sheet of bark, is the primary witness. The oldest text has the youngest paper, and that is not a flaw in the record. It is the record telling you how it was kept.

When many hand-copies of a text disagree, scholars do not simply pick a favourite. They compare the variants and the shared mistakes to reconstruct the closest recoverable ancestor of them all. The monument of this method is the Critical Edition of the Mahābhārata, begun at the Bhandarkar Oriental Research Institute in Pune in 1919 under V. S. Sukthankar and finished in 1966, built by collating nearly thirteen hundred manuscripts in ten scripts. It is one of the great scholarly labours of the century. It is also widely misunderstood. What it reconstructs is the earliest written form the evidence can reach. It does not reconstruct an original epic by a single author, and it never claimed to.

The cities under the soil

The third witness is the spade. The Archaeological Survey of India was founded in 1861 under Alexander Cunningham, and it was the Survey that pulled the Indus civilisation out of oblivion in the 1920s, when Daya Ram Sahni dug at Harappa and R. D. Banerji at Mohenjo-daro, and the director John Marshall announced to the world in 1924 that an entire lost civilisation had surfaced. In a single decade the urban history of the subcontinent grew older by fifteen hundred years.

Archaeology gives what no text can: the texture of ordinary life, the houses and drains and cooking pots, and through stratigraphy, the layering of remains, a relative order of before and after. Turning that order into calendar dates took a further tool. Until the 1950s the Indus was dated by comparison with datable Mesopotamian finds. Then radiocarbon dating arrived and gave the first independent absolute chronology, anchoring the mature Indus phase to roughly 2600 to 1900 BCE. Coins add their own precise thread, often stamped with a ruler’s name and sometimes a year, so that entire dynasties such as the Indo-Greeks are known largely from their coinage. The same bilingual coins, as we saw, helped break the scripts in the first place. The evidence loops back and checks itself.

Outside witnesses, and a witness made of bone

No tradition is the only witness to itself, and India was watched by visitors who wrote down what they saw. The Greek ambassador Megasthenes described the Mauryan capital around 300 BCE, in a book now lost and surviving only as fragments quoted by later writers, which is why he must be used with care. The Chinese Buddhist pilgrims left priceless eyewitness reports: Faxian around 400 CE, and Xuanzang in the seventh century, who studied at the great university of Nalanda. The Persian polymath al-Bīrūnī, in the eleventh century, produced a study of Indian religion and science so systematic it still astonishes. India also broke its own habit once, magnificently, in Kalhana’s Rājataraṅgiṇī, the River of Kings, a verse chronicle of Kashmir written around 1150 CE, though even Kalhana mixes legend into his oldest reigns.

The newest witness is made of bone. Since the 2010s, ancient DNA has let researchers read the movement of whole populations directly from old skeletons. It is powerful and it is partial. It can tell you that people moved, and roughly when. It cannot tell you what they believed, or what they sang at the fire.

Why the honesty is the point

Set the witnesses side by side and a picture forms, sharp in some places and faint in others. Inscriptions give firm political history from Ashoka onward. Manuscripts and the living chant carry the texts, reconstructed with patience. Archaeology and radiocarbon date the cities. Coins, foreign travellers and now genetics fill the gaps and cross-check the rest. What India did not leave, before the medieval period, was a running dated chronicle of itself, and that single absence is why so many early dates are estimates with real margins around them.

To give those dates with their uncertainty intact, to say “about 1500 BCE” and mean the “about,” is exactly what separates history from legend. It is slower and less satisfying than a confident round number. It is also the only honest way to love a tradition this old: to study it as carefully as it deserves, and to refuse it the flattery of false precision.

The stones learned to speak. The discipline is in not putting words in their mouths.
