Well, one thing to keep in mind is that a trade route isn't a straight shot. So a single trader isn't going from Byzantium or China all the way to Britain. Rather these things pass through many many hands. But it is quite fascinating how it all manages to come together, isn't it? We don't have a lot of hard and fast indications of what was being traded and with whom until Offa. And even then, it's a bit of a sketchy record. But we can be pretty sure that Britain was trading both with continental europe and also probably had traders from the Mediterranean visiting.
