The Ancients (History Hit) — "The Romans and China" with Sir Barry Cunliffe
Aired: April 9, 2026 | Host: Tristan Hughes | Guest: Sir Barry Cunliffe

Overview

In this engaging episode, host Tristan Hughes sits down with legendary archaeologist Sir Barry Cunliffe to retell the extraordinary story of how the Roman and Han Chinese empires—separated by thousands of miles—were nonetheless connected by thriving maritime and overland trade routes 2000 years ago. Drawing on his new book, Driven by the Monsoons, Cunliffe presents a reconstructed voyage for Roman goods from Egypt’s Red Sea ports through the Indian Ocean, Sri Lanka, Southeast Asia, and on to Han China—unpacking the dynamic, multicultural networks that made these epic journeys possible.

Key Discussion Points & Insights

1. The Ancient World: Always Connected

• Barry emphasizes that trans-Eurasian connection is not a modern phenomenon. Long before modern globalization, robust networks—overland across the Eurasian Steppe and Sahara, and via the sea—linked distant societies.
• Quote:

  "The world has always been connected... This idea of acquiring things is so important, I think, to humans. They need to acquire things like useless yellow metal that they put around their hands and hang around their necks." — Barry Cunliffe (06:03)

2. Did the Romans and Chinese Know of Each Other?

• Direct contact between Imperial Rome and Han China was rare, but both were aware of each other, largely through intermediaries (notably the Parthians) and the Silk Roads.
• The famous (and often retold) mission of the Chinese envoy Gan Ying in 97 AD, which was stymied by Parthian intermediaries, illustrates how Parthia controlled east-west trade flow and information.
• Quote:

  "The Parthians... commanded the silk routes and they commanded the price of silk. The Romans wanted silk desperately... but [the Parthians] didn't want the Chinese to find another way around to the Romans." — Barry Cunliffe (09:54)

3. Luxury Goods and Complaints Over Trade

• Roman sources like Pliny the Elder lamented the staggering outflow of wealth to India and China for luxury goods (notably silk), reflecting anxieties over balance-of-trade:
  • "India, China and the Arabian Peninsula take 100 million sesterces from our empire every year at a conservative estimate. That's what our luxuries and our women cost." — (Barry reading Pliny, 09:54)
• Chinese sources mention the Roman Empire ("Daqin") and his 166 AD Han history records envoys from "Andun" (Marcus Aurelius), whose gifts (ivory, rhino horn, turtle shell) left Chinese officials unimpressed.
  • "But nothing of a precious nature. So they're saying these are tatty old gifts... I wonder whether they passed themselves off as ambassadors, but that really they were just Roman traders trying to open up a market." — Barry Cunliffe (13:56)

4. The Role of Intermediaries & the Flow of Goods

• Goods (Roman glass, Indian spices, Chinese silk) rarely traveled with the original producers—middlemen and local sailors facilitated the movement of items across far-flung regions.
• Archaeological evidence places Roman glass in Korea and Japan (16:07), mostly via overland Silk Road routes, but also maritime pathways.

5. Mapping the Maritime Journey: Theoretical Reconstruction

A. Roman Egypt to Red Sea Ports (25:17)

• Trade expedition starts in Alexandria, moves up the Nile, overland to Red Sea ports (Myos Hormos or Berenice) via camel caravans.
• Well-fortified caravan routes protected by Roman garrisons.

B. Down the Red Sea to Africa & Arabia (27:51, 29:49)

• Stopping at Adulis (in today’s Eritrea)—a major Axumite port, then through the narrow straits into Gulf of Aden, with cosmopolitan ports teeming with Indians, Arabs, and Africans.
• The Arabian incense ports were in use for a millennium (Kana, Aden) and crucial for trade in frankincense and myrrh.

C. Across the Indian Ocean to India (35:30)

• Use of seasonal monsoon winds enabled open-sea crossings (e.g., to Muziris on the Malabar Coast in Kerala).
• Ports:
  • Barbaricum (mouth of the Indus, Pakistan) — a northern trading hub and site for Silk Road goods.
  • Muziris (Kerala, South India) — a cosmopolitan port with a Roman quarter and even a temple to Augustus.
    • "There are foreigners [in Muziris]... there's a foreigner's quarter. There's even a temple to Augustus." — Barry Cunliffe (39:38)
    • Excavations have revealed coins, harbour works, and a wealth of imported foods (seeds of rice, wheat, grapes, etc.).

D. India to Sri Lanka (43:58)

• By the 2nd century AD, Sri Lanka (Taprobane) became a central hub, with ports like Mantai trading both east and west. Archaeology finds both Roman and Han Chinese objects.
• "Sri Lanka... is now part of the system. You're getting ships coming from the west going to Sri Lanka... it's Taprobane." — Barry Cunliffe (43:58)
• Historical records indicate embassies between Sri Lankan kings and Roman emperors.

E. Bay of Bengal & Southeast Asia (47:43)

• From Sri Lanka, ships crossed the Bay of Bengal, either hugging the Indian coast or going direct to the Malay Peninsula.
• At the narrow Kra Isthmus, goods were often portaged across land and re-embarked on new ships, reflecting how trade was modular and adaptive.
  • Funan (Katigara): In the Mekong Delta, this port city in today’s Cambodia/Vietnam was a crucial crossroads, populated by Indian, Roman, and Chinese traders.

F. Arrival in Han China (54:53)

• Sailors would follow Vietnam’s coast (Champa) to the Red River (near modern-day Hanoi), entering Han China.
• The major Chinese port was Panyu (now Guangzhou); from here, goods and representatives could travel inland to the imperial court.

Notable Moments & Quotes

• On the Silk Road vs. Maritime Routes:

  "The main silk route is that northern step route, the silk roads route, but there was also this southern route by sea... silk was getting down to various places and being picked up at various ocean routes." — Barry Cunliffe (11:36)

• On Trading Ports:

  "Many of the ports along the way, your Roman would have met up with people from Arabia, from India, from the Malay region. These ports were really cosmopolitan." — Barry Cunliffe (17:50)

• On Knowledge Sharing & Cosmopolitanism:

  "People were learning about each other there and learning each other's ways and picking up information about where to go, where the best deals could be done." — Barry Cunliffe on Socotra island (33:26)

• On Human Nature and Mobility:

  "It's a driving force, it's acquisition. Humans, the most mobile of all animals... always there is movement and contact and trade and exchange. I think the Rome-China story is probably the most exciting of them all." — Barry Cunliffe (56:58)

Extended Questions & Big Picture Themes

• The collapse of the Han Dynasty may have limited Chinese engagement with western sea routes (58:31). Barry suggests China’s geography inclined it toward overland routes until the Ming Dynasty, when maritime exploration briefly flourished.
• Roman goods found in Korea and Japan probably traveled via secondary regional networks.
• The episode showcases both the interconnectedness and limitations of ancient civilizations—much closer than we imagine, but still subject to the realities of geography, politics, and human ambition.
