Really and for true?
Cornwall was the ONLY source of tin for ancient Europe?
The ancient Cymru must have been sittin’ pretty in them days.
Don’t you know that Jesus visited the tin mines as a child? His biblical record stops at ~13 years and doesn’t start up until after his 30th. During that time, he traveled the world with his uncle to visit different sites where the Jews were engaged in commerce.
Of course, this is all legend (see Blake), but there is fascinating evidence of long lasting ties between the Hebrews and the British Isles.
