The following quick post is really just a bit of fun, designed to look briefly at the potential evidence for a spreading awareness of Britain's existence outside of Northwestern/Atlantic Europe...
The map below plots some of the possible evidence for such an awareness, both in terms of the earliest literary and cartographic references to Britain (in black) and some potential literary and archaeological evidence for the physical presence of people from Britain in those areas (in red).

[mod note] This is a very cool little article, tracing references through regions and centuries on a sort of timeline. TONS of links for further reading, and images of artworks and artifacts.
