Transcript: The Ancient Indian History Our Schools Don’t Teach – William Dalrymple

Read the full transcript of British journalist Ash Sarkar in conversation with Scottish historian William Dalrymple on “The Ancient Indian History Our Schools Don’t Teach”, on Downstream IRL, premiered on August 10, 2025.

Welcome to a Different Kind of History

ASH SARKAR: Hi! Welcome to Downstream IRL. As I’m sure you’re all aware, popular historians in this country can be a bit of a mixed bag. So on the one hand, you’ve got those who say the empire was great. “What are you whining about? You didn’t even deserve the fucking trains anyway.” And on the other, you’ve got many people who can tell fascinating stories about individuals, but don’t really want to challenge dominant narratives of cultural superiority or indeed, our sense of what’s normal and advantageous today.

William Dalrymple has, however, cut a very different path. Combining travel writing, art history, archaeology, architecture, cultural commentary, his books are both richly researched and also compellingly written. His works on the history of India, the British Empire, and the Islamic world have challenged dominant narratives around civilization, conquest and cultural exchange.

And in addition to his work as a historian, he co-founded the Jaipur Literary Festival, and his podcast with Anita Anand Empire has hit 80 million downloads. Those are Ariana Grande numbers, mate. That’s insane.

We’re here to talk primarily about his book The Golden Road: How Ancient India Transformed the World, which is, I think, a kind of friendly retort to the Silk Roads theory, which says that the land trading route from China through Central Asia and into Europe, that’s the central way for thinking about the kinds of exchanges between east and West.

Instead, Dalrymple looks at sea trading routes from India westwards into the Red Sea, eastwards into the Mekong Delta, and traces the spread of people, ideas, religion, philosophy, numbers, silk, and even the humble rhubarb. I’m sorry, my husband’s going to kill me for doing a Yorkshire accent, but what can I say?

William Dalrymple, welcome to Downstream. I love that you’re walking on with a can of lager.

WILLIAM DALRYMPLE: Not just any old lager.

ASH SARKAR: Hells, let’s just jump into it.

WILLIAM DALRYMPLE: Sure.

Alexander the Great: A Forgotten Encounter

ASH SARKAR: I’m Alexander the Great. Less of the skepticism, please. I’m Alexander the Great.

WILLIAM DALRYMPLE: I never doubted it, Ash.

ASH SARKAR: And I’ve done a load of conquering. I finally show up in India. What am I making of what I find in ancient India and what are they making of me?

WILLIAM DALRYMPLE: Well, the second question first. There’s not a single reference to Alexander the Great in any Indian source.

ASH SARKAR: What? Why do I have so many Indians in Alexander, then? What’s going on?

WILLIAM DALRYMPLE: So we think of it as this sort of extraordinary moment in Western history with this great conqueror. Indians shrug it off and no one records it. Nobody knows. Some Indian historians doubt that it happened. I think it did happen, but it’s so unimportant in the wider flow of things in India that it’s simply not recorded.

But what he comes to and what develops in the centuries to come is a civilization about which in the west, but astonishingly in this country, which had 300 years of relations with India and has this enormous Indian population here, it’s astonishing how little we know about ancient India in this country.

The Forgotten Giants of Ancient Indian Science

To give one example, I suspect everyone in this audience knew about Archimedes in his bath, shouting “Eureka” by the age of 6, 7 or something.

ASH SARKAR: I’m really overestimating the quality of my education for sure.

WILLIAM DALRYMPLE: But it’s a name which, you know, the idea of this Greek and his toga or whatever it is, shouting “Eureka.” It’s something kids learn about equally. By the age of 10, most people come across Pythagoras and his theorem.

Now that’s all very well and Joe will be very pleased that we’re studying all these wonderful Greek figures, but we should also know, and we don’t, names like Aryabhatta and Brahmagupta, who the South Asians in the audience will know this and have uncles that have sent them WhatsApps about it from their childhood. But all the white Brits have never heard of these people. You can go to universities, you can go to Oxford and Cambridge and simply these names will not register.

But they are crucially important. Aryabhatta, in about 350 AD comes up with the exact circumference of the Earth. The distance of the Earth to the moon, the distance of the Earth to the sun, the fact that we live in a heliocentric universe, that the Earth goes round the sun.

ASH SARKAR: Lucky guesses?

WILLIAM DALRYMPLE: No, because he gets the figures exactly right. And that’s a thousand years before Galileo.

Brahmagupta, who takes his ideas forward. Brahmagupta, sitting on a mountaintop in Rajasthan, a place called Mount Abu, and he’s meditating on this idea of Sunya, which is an idea in both Buddhist and Hindu civilization about the void. And he comes up with definitions of zero.

So zero is, for example, the number you get when you subtract a number from itself. And he realizes that zero is not just an absence or the space between positive and negative. He realizes it’s a number with its own qualities and therefore you can do, well, number one, place value, tens, hundreds, thousands, tens of thousands, hundreds of thousands. You can also do things like algorithms and algebra and all sorts of fancy mathematical tricks. And it’s basically Brahmagupta who take zero, adds it to the existing nine Indian number symbols and creates our numbers.

The Journey of Numbers and Ideas

ASH SARKAR: What’s the relationship between Indian numbers and what we call Arabic numbers?

WILLIAM DALRYMPLE: They’re the same. We call them Arabic numbers because we got them from the Arabs, but the Arabs get them from India and they still call them Hindi numbers.
