Well I suspect that the writers of the article didn't think it through either.
And 1768 is only just over 200 years later.
I must also point out that most large stone moving projects took place in the tropics where there was no ice available which is why the technique was not used for the pyramids or the Mo'ai on Easter Island.
I am aware that the ...[text shortened]... riction in either civilization.
Its even possible that that sentence was added by a journalist.
I am sure everyone who ever tried to walk on ice knew it was slippery, that would have been obvious 20,000 years ago much less in the year 1500 but did anyone in Europe actually use it in those years? Probably not. Don't forget, the Chinese invented gunpowder around the year 1000, what, 500 odd years before Europe? Of course they didn't really know what to do with it, using it for pretty fireworks and such, they didn't really know what they had.
Just like the Babylonian batteries, it seems now fairly certain they had electricity some 5000 years ago but it was tied up in the religious rites of the day, electroplating gold onto statues and there it stood till my guess is the last priest died before being able to pass the secret to his acolytes and there went electricity for 5000 years.
The ancient Greeks may have know about electricity also, they seem to have had some kind of test of the gods thing where some voltage was applied to these brass handles and you could feel the presence of god by being shocked so some degree. So again it was not recognized as useful beyond religious ends. Just think, if they had known what they had back 5000 years ago and then again 3000 years ago, either of those civilizations could have walked on the moon. Lost opportunity and they didn't even know it.
