Latest / Trade Routes That Changed Human History Forever — Fexingo History / The Kharosthi Script: Silk Road's Lost Writing
Transcript
- Lucas: So we've talked a lot about the goods that moved along the Silk Road — silk, spices, horses, paper. But one of the most important things that traveled those routes was writing itself. And today I want to look at a script that most people have never heard of, but it was absolutely crucial for centuries: Kharosthi. Luna: Kharosthi — that's the one that looks kind of like Aramaic written sideways, right? Lucas: Exactly. It's written from right to left, and it's derived from the Aramaic alphabet, which makes sense because Aramaic was the administrative language of the Persian Empire. When Alexander the Great conquered Central Asia and parts of India, the Greek influence mingled with the local traditions, and Kharosthi emerged probably around the 3rd or 2nd century BCE in the region of Gandhara, which is modern-day Pakistan and eastern Afghanistan. Lucas: It was used to write the Gandhari language, a middle Indo-Aryan language, and it became the official script of the Indo-Greek kingdoms and later the Kushan Empire. The earliest dated Kharosthi inscriptions come from the time of the Mauryan emperor Ashoka, who set up edicts carved on rocks and pillars across his empire. Two of those edicts, at Shahbazgarhi and Mansehra, are in Kharosthi. Luna: Wait, so Ashoka's edicts were written in different scripts depending on the region? Lucas: Yes, exactly. In the eastern parts, they used Brahmi, the ancestor of most modern Indian scripts. In the northwest, they used Kharosthi. It shows how the Mauryan administration adapted to local writing traditions. And that's a pattern we see again and again on the Silk Road — scripts traveled with merchants, monks, and administrators, and they adapted to new languages. Lucas: Kharosthi really flourished under the Kushan Empire, especially in the first few centuries CE. The Kushans controlled a huge territory from Central Asia down into the Indian subcontinent, and they used Kharosthi for administrative documents, coin legends, and Buddhist dedications. There are thousands of Kharosthi inscriptions on copper plates, stone, and even on birch bark manuscripts. Luna: I've heard about those birch bark manuscripts — the Gandharan Buddhist texts. Aren't they some of the oldest Buddhist manuscripts we have? Lucas: That's right. In the 1990s, a collection of birch bark scrolls written in Kharosthi surfaced — they're known as the Gandharan Buddhist texts, and they date from around the 1st century BCE to the 3rd century CE. They contain early versions of Buddhist scriptures, including the Dharmaguptaka tradition. These are among the oldest Buddhist manuscripts ever found, and they show how Buddhism spread along the Silk Road, carried by monks who wrote in Kharosthi. Lucas: But Kharosthi wasn't just used in India. It spread north into the Tarim Basin, in what is now Xinjiang, China. At sites like Niya, the British archaeologist Sir Aurel Stein discovered hundreds of wooden tablets and documents in Kharosthi from the 3rd to 4th centuries CE. These were administrative records of the Shanshan kingdom, a Buddhist state along the southern Silk Road. Luna: So Kharosthi was used from modern-day Pakistan all the way to the edge of the Taklamakan Desert. That's a huge range. Lucas: It is. And the documents from Niya are fascinating — they include tax records, legal contracts, letters, even a list of camel fodder. They give us a direct window into the daily life of a Silk Road oasis kingdom. The script was written on wooden tablets, often with a string and a clay seal to keep them secure. Some were even written on leather. Lucas: Now, here's something a lot of people don't realize: Kharosthi was deciphered largely through bilingual coins. The Indo-Greek kings minted coins with Greek on one side and Kharosthi on the other. By comparing the names of the kings, scholars could figure out the sounds of Kharosthi. It was a classic case of a bilingual key, much like the Rosetta Stone. Luna: That's amazing. So the same coins that helped us understand the Indo-Greek kingdoms also unlocked the script. Lucas: Exactly. And the study of those coins really took off in the 19th century. Scholars like James Prinsep and Alexander Cunningham used them to piece together the history of the region. It's one of those beautiful moments where numismatics and linguistics come together to rewrite history. Lucas: We deliberately don't run ads on these. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. Luna: Yeah, and it really does make a difference. Keeps the show exactly what we want it to be. Lucas: For anyone coming with us through these conversations about world trade routes, we appreciate that. So back to Kharosthi — by about the 4th or 5th century CE, the script began to decline. The Kushan Empire fell, and the Gupta Empire in India promoted Brahmi instead. In Central Asia, the rise of the Sogdians and the spread of their script, which was also derived from Aramaic, gradually replaced Kharosthi. Lucas: By the time of the Tang dynasty, Kharosthi was essentially a dead script, except in a few isolated pockets. But its legacy lives on in the manuscripts and inscriptions that survive. And there's still a lot we don't know — many Kharosthi documents remain untranslated, and new ones are still being discovered. Luna: Are there any places today where Kharosthi is still used, even symbolically? Lucas: Not really. It's a completely dead script. But it appears on banknotes and stamps sometimes as a nod to history. For example, the Pakistani rupee once featured a Kharosthi numeral. And in the region of Gandhara, you can still see Kharosthi inscriptions on ancient Buddhist stupas and monasteries. It's a reminder of a time when this script was the lingua franca of trade and religion across a vast swath of Asia. Luna: It's incredible how something as simple as a writing system can tell us so much about the movement of ideas and people. Lucas: Absolutely. And Kharosthi is a perfect example. It started as a local adaptation of Aramaic, got adopted by Greek kings, used by Buddhist monks, and then carried by merchants all the way to China. It's a microcosm of the Silk Road itself — a fusion of cultures, languages, and traditions, written in ink and carved in stone. Luna: Thanks for bringing this one to light. It's a side of the Silk Road I'd never really thought about. Lucas: Glad you enjoyed it. There's always more to uncover. And if you want to explore further, I highly recommend looking up the 'Gandharan Buddhist texts' — some of them are even available online. It's one thing to read about history, but to see the actual handwriting of a monk from 2,000 years ago — that's something else entirely.
