Follow the link in post #7 and you'll see that it is, at the least, very old mystical nonsense. Due in part to the tin mines of Britain there was more commerce between it and the Mediterranean lands then you might imagine.
Another fine story is that Jesus Christ traveled to Britain before he took up his recorded ministry in Israel. William Blake referenced that legend in a poem complaining about the ugly factories springing up at the beginning of the industrial age. (For reasons I have never understood it became the school hymn of my high school in Colorado).
And did those feet in ancient time
Walk upon England's mountains green?
And was the holy Lamb of God
On England's pleasant pastures seen?
And did the Countenance Divine
Shine forth upon our clouded hills?
And was Jerusalem builded here
Among these dark satanic mills?
Bring me my bow of burning gold!
Bring me my arrows of desire!
Bring me my spear! O clouds, unfold!
Bring me my chariot of fire!
I will not cease from mental fight,
Nor shall my sword sleep in my hand,
Till we have built Jerusalem
In England's green and pleasant land.
