I'm at
university right now, studying classics(ancient rome and
greece), and this reminds me of something my prof told me. He was
participating in one dig where they ended up uncovering a grand total
of about ten *tons* of potsherds. That's about nine thousand kilograms
for the metric inclined.
The problem is that most of them had no real diagnostic value - no
markings, nothing unusual. Not really much to be learned from them. Of
course, you couldn't put them in a museum. All the museums in the world
put together don't have space for ten tons of random, unmarked
potsherds. I had thought they should see about selling them, lots of
people would love to have a piece of ancient greece - but, no, my prof
pointed out that they would then become fodder for forgers. So, what to
do? Fortunately, at the time, Athens Airport was building a new runway
- and needed fill. Those potsherds are buried under the runway.
My cousin was on a dig like that, maybe 15 years ago, I think in
Sicily. I think she said that on that occasion, they just used a
backhoe to move the pile over a bit.
And someday we will be using backhoes to move over piles of PeeCees,
Macs, iPhones and Droids.
