Latest / The Srivijaya Empire: Southeast Asia's Forgotten Maritime Superpower — Fexingo History / Srivijaya's Lost Library: The Pagaruyung Copper Leaves
Transcript
- Lucas: So we've talked a lot about Srivijaya's inscriptions — the Kedukan Bukit, the Telaga Batu — but there's one set of texts that's always fascinated me, and it comes from the very end of the Srivijaya period, or just after. The Pagaruyung Copper Leaves. Luna: Copper leaves? Like, actual leaves made of copper? Lucas: Exactly. They're thin copper plates, shaped vaguely like palm leaves — because in Southeast Asia, traditional manuscripts were written on dried palm leaves. So these are metal versions of that format. There are 18 of them, discovered in the 19th century in the highlands of West Sumatra, near a place called Pagaruyung. They date from the 14th century, during the reign of a king named Adityawarman. Luna: We've mentioned Adityawarman before — he was the one who took over from Srivijaya, right? Lucas: Right. He was a prince of Malayu — that's the Jambi-based kingdom that absorbed Srivijaya — and he eventually established his own kingdom called Malayapura in the Minangkabau highlands. The copper leaves are from his court. And what's remarkable is that they contain Buddhist texts, royal decrees, and legal codes — all inscribed in a mix of Sanskrit and Old Malay. Luna: So it's like a library, but made of metal. Lucas: Exactly. And these leaves are incredibly rare. They survived because copper doesn't rot like palm leaves. But only 18 have been found — there might have been hundreds originally. They were probably stored in a royal archive or a temple library, but most have been lost to war, theft, or simply decay. The ones we have were found by Dutch colonists in the 1800s, and they're now kept in museums in Jakarta and Leiden. Luna: What do they actually say? Lucas: Well, the most famous one is inscribed with the Buddhist mantra "Om Mani Padme Hum" — that's the Avalokiteshvara mantra — repeated many times. Another contains part of the Karanaavyuha Sutra, which is a Mahayana Buddhist text. But there are also secular inscriptions: tax regulations, land grants, and oaths of loyalty to the king. They give us a direct window into how Adityawarman ruled. Luna: An oath — like a loyalty pledge? That sounds like the Telaga Batu inscription from Srivijaya. Lucas: Very similar. In fact, the Telaga Batu inscription from 7th-century Palembang also has a curse against those who betray the king. So there's a clear continuity. Adityawarman was positioning himself as the heir to Srivijaya's Buddhist kingship. He even used the title "Adityawarman" — which means "protected by the sun" — and claimed descent from the Sailendra dynasty, who built Borobudur. Luna: So he was deliberately linking himself to the Srivijayan glory days. Lucas: Absolutely. The copper leaves are part of that propaganda. By having Buddhist texts inscribed on metal, he was showing that his kingdom was a center of Buddhist learning and piety. And by issuing decrees on copper, he was creating permanent records of his authority. It's the same logic as the stone inscriptions of earlier Srivijaya — but more portable, more durable. Luna: Were the copper leaves used as actual administrative documents, or were they more ceremonial? Lucas: Probably both. Some of them are clearly practical — like a tax list or a land grant. But others seem purely ritual, like the mantra leaves. They might have been buried as consecration deposits in temples. In fact, one of the leaves was found inside a stone box at a temple site called Candi Padang Roco, near the Amoghapasa statue we mentioned in an earlier episode. So they had a religious function as well. Luna: So what happened to the rest of them? Why only 18? Lucas: That's the big mystery. The Minangkabau highlands were a remote area, and after Adityawarman's kingdom declined, the copper leaves were probably scattered. Some might have been melted down for their metal. Others could still be buried in temple ruins. There's also a legend among the Minangkabau people that a great library of copper leaves existed in the royal palace of Pagaruyung, but it was destroyed during a war in the 19th century — the Padri War, which was a conflict between Islamic reformists and traditionalists. If that's true, we've only seen fragments of a much larger corpus. Luna: That's heartbreaking. All that knowledge lost. Lucas: It really is. But the surviving leaves still tell us a lot. For example, they show that even after Srivijaya's political power faded, its Buddhist and Sanskritic culture continued in the highlands. Adityawarman's court was a blend of local Minangkabau traditions, Malayu heritage, and Indian-inspired Buddhism. The copper leaves are like a fossil of that hybrid world. Luna: I remember you mentioned the Amoghapasa inscription earlier — that was also from Adityawarman's time, right? Lucas: Exactly. The Amoghapasa inscription is a stone tablet from 1347 that records Adityawarman dedicating a statue of the bodhisattva Amoghapasa. It's written in Sanskrit and Old Malay. So together with the copper leaves, we have a pretty good picture of his reign. But the copper leaves are unique because they're not just one-off dedications — they seem to be part of a systematic archive. Luna: So what's the most important thing we've learned from them? Lucas: I think it's the continuity. The leaves prove that the Srivijayan model of Buddhist kingship — where the ruler is both a temporal lord and a patron of the sangha — survived for centuries after the fall of Palembang. Adityawarman wasn't a Srivijayan king, but he consciously adopted their symbols and practices. That tells us that Srivijaya's legacy wasn't just a footnote — it shaped the political culture of Sumatra for generations. Luna: And the leaves themselves are a reminder of how fragile historical evidence can be. Lucas: Exactly. If those 18 plates hadn't been found by Dutch officials in the 1800s, we might not even know that Adityawarman had a written archive. It makes you wonder what else is still out there, buried in the jungle or hidden in local villages. The story of Srivijaya and its successors is still being written — one artifact at a time. Luna: I hope more are found someday. Lucas: Me too. And there's some effort — Indonesian archaeologists are working in the Batang Hari region, where Adityawarman's capital might have been. But the area is remote, and funding is limited. Each new discovery could rewrite what we know about this period. For now, the copper leaves remain one of our most precious windows into the world after Srivijaya.
