Many ancient societies commanded an elaborate grasp of the movements of the sun, moon, stars and planets using little or no technology. In this book, Professor Aveni considers the achievements of the Incas and the construction of Stonehenge. No library descriptions found. |

The writing is pretty dry. And it goes into a lot of detail about the calculations that are used to track the motions of heavenly bodies, keep accurate calendars, predict eclipses, and so forth. These calculations are fundamental to the subject matter, but I have to admit, they inevitably made my eyes glaze a little bit. I'd say this book is probably great for anyone who wants to really get into those nitty-gritty details -- it even provides exercises in the back of the book if you want to try it yourself! -- but is less appealing for someone with a more casual interest in astronomy or archeology.
I did learn some interesting things from it, though, such as the fact that Stonehenge as we know it today actually took shape over something like a thousand years, and the fact that the ancient Mayans used a base-20 counting system. ( )
