Yup...I reckon they went w a y further north. I've read that the Phoenicians traded westward to the Straits and beyond via the south side of the Med while the Greeks went along the north side. Who transported the Orkney vole, origin in the Levant and other stronghold on the Belgian coast, well, take your pick. The stone carvings in Denmark of boats look like hippoi, with their raised prows and decorations atop are very similar to Viking longships but predate them by many centuries. Progenitors? The Greek boat doesn't appear to have a prow decoration but of course it could have fallen off..but, hey, what remains is remarkable.
