I would like the pieces to come from Lewis. I really would.
But there is very strong doubt and no proof.
Despite all the evidence pointing away from Lewis, on first contact the BM
said I cannot prove they never came from Lewis so they do not to have
to prove they did. Eh?
(Their attitude has changed quite a bit since then).
There is this Lewis priest who who appears in some of the myths
and he is in Edinburgh at the same time as Forrest who was a "dealer."
(he always described as a 'dealer'
Very plausible that when carrying out fresh burials at a church
(most of which are built on the sites of pagan worship)
they stumbled upon these graves and the pieces.
"Sell the pieces to make to money to fix up the church and make up a
story where they came from."
Forrest bought them no questions asked.
Somebody knows where they came from and if it was Lewis it is being
kept a secret to perhaps hide shame and stop armies of treasure seekers
from digging the place up.
I nearly have a full set of these things in all sizes.
People see one, buy it and give to me as a surprise present.
I'll visit Lewis one day and bury them in the sandbank.
They are not chess pieces.
