The exhibition of Nasca

I went to National Museum of Nature and Science.
It is one of my favorite places in Tokyo. It was built more than 100 years ago and was renovated a few years ago. It is exhibiting many things the museum has collected for 100 years. The way of exhibiting is really modernized. I like the mixture of the history an high technology this museum has.
Now a special exhibition is being held there. It is the exhibition of Nasca, an ancient culture in Peru, which is famous for the huge picture drawn on a ground.


I haven't known nothing except the big ground picture, but I was very impressed the pictures painted on earthenware pots. The pictures were lively. The collar of the pots was clear and beautiful though they were made more than 1500 years ago.
I wonder why such sofisticated culture had not developed. I think that the fact that the culture in Nasca didn't have letters was one of the reasons of it.
