To provide a detailed explanation of this topic, it is first necessary to make an important historical clarification: The premise merges two distinct—though equally fascinating—Viking Age phenomena that did not actually overlap in the way described.
While Viking Age Scandinavians did carve runes into ancient Central Asian coins, and the Varangian Guard did serve as mercenaries in Constantinople, the Byzantine Empire did not pay the Varangians in Central Asian coinage. Furthermore, the routes these two phenomena represent are geographically and economically distinct.
To understand how these pieces actually fit into the history of the Viking expansion, we must look at them as two separate networks: the Islamic Silver Trade (Volga Route) and the Byzantine Mercenary Network (Dnieper Route).
Here is a detailed breakdown of the real history behind these elements.
1. The Central Asian Coins and Runic Graffiti
During the 9th and 10th centuries, there was a massive flow of silver from the Islamic world—specifically from the Abbasid Caliphate and the Samanid Empire (based in Central Asia)—into Scandinavia.
- The Route: Swedish Vikings, known in the east as the Rus', traveled down the Volga River to trade heavily with Islamic merchants around the Caspian Sea and Bulgar markets. They traded slaves, furs, and amber for silver dirhams.
- The Hoards: Millions of these Central Asian and Islamic coins made their way back to Scandinavia, with massive hoards discovered on the Swedish island of Gotland.
- The Runes: Occasionally, archaeologists find Islamic dirhams with runic inscriptions scratched into them (runic graffiti). These runes typically represent personal names (indicating ownership), magical symbols, or religious invocations. Additionally, Vikings routinely "pecked" or scratched these coins with knives to test the purity of the silver.
2. The Varangian Guard and Constantinople
The Varangian Guard was an elite unit of the Byzantine Army, serving as the personal bodyguards of the Byzantine Emperor. They were formally established in 988 AD by Emperor Basil II.
- The Route: Unlike the Volga merchants who went east to Central Asia, the Varangians traveled south down the Dnieper River—the famous "Trade Route from the Varangians to the Greeks"—across the Black Sea to Constantinople (which the Vikings called Miklagard, "The Great City").
- The Payment: The Byzantine Empire had a highly sophisticated and centralized economy. They did not pay their elite guards in foreign Central Asian dirhams. The Varangians were paid handsomely from the Imperial Treasury in Byzantine coinage—primarily gold nomismata (or solidi) and silver miliaresia—as well as in fine silks and the right to plunder the imperial treasury upon the death of an emperor (a custom known as polutasvarf).
3. Why the Two Don't Mix
There are two main reasons why runic Central Asian coins cannot be used to trace Varangian Guard payments: 1. Economic Sovereignty: The Byzantine Empire minted its own highly regulated currency. Passing off foreign Islamic/Samanid silver as imperial payment to the Emperor's most elite guards would be historically inaccurate. 2. Chronology (The Silver Crisis): The influx of Central Asian silver dirhams into Scandinavia peaked in the 10th century and largely dried up by the 970s due to a silver shortage in the Islamic East. The Varangian Guard was not formally established until 988 AD, meaning the height of the Central Asian coin trade had already passed by the time the Varangian Guard became an institution.
4. The Real Runic Traces of the Varangian Guard
While Central Asian coins do not trace the Varangians in Constantinople, runes carved into stone absolutely do. If you want to trace the presence of the Varangian Guard in the Byzantine Empire through runes, historians look at:
- The Hagia Sophia Runes: Inside the Hagia Sophia in modern-day Istanbul, there are runic inscriptions carved into the marble parapets of the upper gallery. The most famous one translates to "Halfdan carved these runes" (essentially, "Halfdan was here")—the bored graffiti of a Varangian Guardsman attending a long church service.
- The Piraeus Lion: A massive marble lion originally located at the port of Athens (then a Byzantine territory). In the 11th century, Scandinavian mercenaries carved a long, winding runic inscription into the shoulders of the lion commemorating a fallen comrade. (The lion was later looted by the Venetians and now sits in Venice).
- Swedish Runestones: There are numerous runestones raised in Sweden commemorating men who "died in Greece" (the Norse term for the Byzantine Empire) or who returned home wealthy with Byzantine gold.
Summary
Viking Age runes inscribed on Central Asian coins are vital artifacts for tracing trade routes between Scandinavia and the Islamic East via the Volga River. However, they play no role in tracing the payment routes of the Varangian Guard. The Varangians were paid in Byzantine gold and silver, and their legacy in Constantinople is traced not through coins, but through runestones back home and runic graffiti carved directly into the ancient monuments of the Byzantine Empire.
