It turns out China's famous terra-cotta army might have been influenced by the ancient Greeks.
Experts studying the sculpted warriors point to two important pieces of evidence.
And one study found European DNA in northwest China. That suggests Westerners may have lived in the area around the time the army was created.
If true, that would put Europeans in China about 1,500 years before Marco Polo first arrived.
The terra-cotta army was built by China's first emperor, Qin Shi Huangdi. The army was built to guard him for all of eternity. The statues were discovered in 1974.
One of the archaeologists at the site told the BBC, "We now have evidence that close contact existed ... before the formal opening of the Silk Road."
And a historian studying the warriors said there might have even been Greek artists at the site to train locals.
