Every where we hear that they did not use the wheel. I wonder if these

There is an awful lot we don't know about previous civilizations and a lot
of what we have thought we knew has been revised multiple times since we
first "knew" it. Take a close look at some of the 'religious artifacts'
and you will see that some will produce a couple volts if you fill them
with vinegar. Was that how they were used? We don't know ... and that's
why they are lumped in with all the other 'religious artifacts'.

I seem to recall a National Geographic article many, many years ago in which
they described a shipload of batteries that had been discovered. The thing
is the ship sank about 2000 years ago. The speculation was that the Greeks
had discovered electroplating--the batteries were built into amphorae, but
there wasn't much else they were likely to be but batteries given the
conformation.
