The story started from a battle between the Chinese soldiers and the Hun tribes in 36 BC.
An Oxford history professor Homer Hasenphlug Dubs came over an ancient document written by the
Chinese historian, Ban Gu (32-92 BC). It describes an expedition of two generals of
the Han Dynasty (206 BC - 220 AD), who led 40,000 men to conquer Zhizhi (Dzhambul, Kazakhstan).
They encountered a nomadic army1 entrenched in a camp surrounded by double wooden palisade.
In the ensuing fight, a strange band of nomads locked their round shields shoulder to shoulder and formed a screen like fish scales.
The Han army victoriously defeated the nomads. About 150 nomads of the band were captured and brought
back to China. Emperor Yuandi (48-33 BC) granted the captives amnesty and settled them in a town called
Lijian (or Liqian) in western China. The nomads were retained to serve as local militia for the Emperor.
However, Professor Dubs compared the tactics of the nomads with a more disciplined army.
The use of wooden fortifications and the fish-scale formation were unusual for the tribal warriors of the Huns.
Particularly, the unique formation was similar to the Tortoise (Testudo) formation that had only been used by the Roman Legionaries.
In 1955, Professor Dubs concluded that the nomads were the remnants of a disintegrated Roman army in the battle of Carrhae
(southeastern Turkey) in 53 BC.2
The name of the outpost town Lijian was the translation of Alexandria that the Han referred to Rome.
In 1957, Dubs published a book entitled A Roman City in Ancient China.
After 30 years, an Australian writer and adventurer, David Harris, read Dubs' book and was intrigued by this story.
He came to China to search for Lijian. He met a scholar at Northwest University of Nationalities in Lanzhou.
Guan Yiquan had already researched about Lijian for about 10 years.
He identified Zhelaizhai village near Yongchang, Gansu Province as the probable location of Lijian in the late 1980's.
Many of the villagers had high-bridge noses and curly brown (blond?) hairs, and they had a custom of worship of ox.
They also practised bull dancing and bull sacrifices. In 1991, Harris published his book, Black Horse Odyseey,
sharing his experiences of the journey. However, Guan died in 1998 before he finished his research and his book
about Roman CIty.
Dubs' theory has not been universally accepted and there are still arguments.
Some researchers have gone to the Lijian area to perform genetic research on local villages
who have prominent Caucasian features. Some problems arise that the area was located in the trade route
of the ancient Silk Road. Various ethnicities from as far as the Mediterranean came and went.
Moreover, soldiers in the Roman legions were supposed to consist of peoples of different ethnic and
national backgrounds. Several tombs of Han Dynasty were uncovered in Yongchang in 2003.
The burial chamber of one tomb was large for a person of 1.8 metres tall. Some hope that these
finds might provide more concrete evidence for the theory. Elsewhere, a Roman inscription of 2nd-3rd centuries
has been found in eastern Uzbekistan in the Kara-Kamar cave complex. The relic has been analysed to belong to
some Roman soldiers of the Pannonian Legion, XV Apollinaris.
It is not important to know whether the existence of some errant Roman Legionaries,
as the Roman republic and Han dynasty had already known trades through intermediaries.3
There are official records of emissaries who claimed to come from Rome and presented themselves before the Han imperial court
in 144 AD. There are also records written by Florus, a Roman historian, which described several envoys
sent by a Roman emperor to Han imperial court. It is useful to know if ancient persons would journey or wander a long and hazardous distance
from the Mediterranean area to China.4 More important it is significant to put some insight into
how the exchange of ideas and knowledge between two physically isolated peoples.
