Teotihuacan at Quai Branly

Today I went to see Teotihuacan at the Musée du Quai Branly (here's a link in English).  It was my first time visiting this art museum (focused on the far flung regions of the world) so I also went through part of the main collections (sticking with Americas since I'd already spent 2 hours on that). 

It was enjoyable - a part of history I don't know at all, so I learned a good deal.  I'm always astonished though, when I look at the development of the populations in the Americas at how far behind on most technology they were for so long (writing, sciences, etc).  The art too seems so primitive, even if some of it is lovely.
