A. Evidence about 10th century trade networks
There are only two ways Vikings could have gained gold from the middle east, raiding and trading. Despite what many people believe, the Vikings were excellent traders, following rivers all across Europe. Many people believe that the Vikings traded in the Middle East for Damascus steel, making their own weapons superior to those in England and France.
