Castles on the Rhine aren't there accidentally. The Rhine
is a big river, and ever since boats were invented, this river has been
Europe's most valuable means of commerce.
For millennial bends in the river provided ideal spots for bullies to
build castles overlooking bends and tributaries to extract fees from merchants
needing to go upstream and down.
Toledo was born with that idea in mind; but Spanish
rivers are fewer and don't command much commerce. Still, Toledo is imposing, looming over the
plain to the north like a sentinel. A
military couldn't do much about Spain without controlling this city built on a
huge rock. It has the fewest level
streets of any European city.

Actually, I went to Toledo because I'd been told that it
is the number one place in the world to see how Damascene is made. The number one shop is just north of the monster
rock that is the city.

When Isabella and Fernando rooted out the last of the
Moors (who were mostly north African), some Spaniards had mastered this mostly secret
art of welding steel to gold.
If it had been the high season, I might have been out of
luck to learn much; but as soon as I showed interest in the torches, the
supervisor of the shop I examined gave me a tour that lasted all afternoon. The
lead welder explained why the torches
were of varying sizes, how they fused the steel and gold, and how the black is
applied. I was allowed to meander everywhere, which was about the size of two
tennis courts. As you might expect, not the tiniest amount of gold ever
hit the floor, or disappeared. A little steel
might be burned away, but very little of that either.
Once I commented on an interesting steel design high on a
wall. The foreman instantly went ballistic.
"EL CID!!!" he yelled.
When he eventually cooled off enough to speak at a pace I
could track, he led me to understand that a movie company (American) had
produced the film "El Cid" on location near Toledo and contracted for
all sorts of welding and weaponry and other props useful in the film. But they
had not been very forthcoming with cash when due.
"Hollywood!" my tutor finally grumbled, drawing
a finger across his throat. When he eventually stopped sputtering, he murmured something
that was probably just as well I couldn't translate.
At last he smiled. He pointed toward a large sign outside
the shop that told visitors there was a forty percent discount on Damascene
that day.
“For the buses,” he said. “Means nothing." Then he
added, "Don't buy when the buses are here. When there is just you, then
buy. Not forty percent... Eighty percent.”
I still have the bolo I'd watched him make from a blob of
gold and a piece of steel. AND I got it
at eighty per cent off some price he invented because "the bus
people" were not shopping.
