Query: Rather dry and dull.

I found this book made a fascinating subject really boring. I had a tough time finnishing it.In all fairness, I learned quite a few interesting things. One of them being that the Greek civilization was not so great after all. This civilization developed great intellect, but no technological innovators. Their technology relied on harnessing the energy of their slaves period. They had no incentive to innovate, that would have caused an idle and restless underclass prone to civil unrest.I am sure there must be another much more interesting book about the same subject.
