The Crystal Skull

I was at the museum yesterday and I saw a Crystal Skull there. I liked it very much because it is very difficult to make a skulpture like this. Here is some information about the skull which I took from the internet.
The crystal skull is probably European, 19th century AD. Large quartz crystal skulls have caused great interest since they began to be shown in public and private collections, during the second half of the nineteenth century. Some of them have been attributed to the work of ancient Aztec, Mixtec or even Maya stone workers in Mexico. Others are said to be examples of colonial Mexican art, for use in churches, perhaps as bases for crucifixes.Large quartz crystal skulls have generated great interest and fascination since they began to surface in public and private collections, during the second half of the nineteenth century.

So, that's all what I enjoyed at the museum, but I want to visit it another time to find and enjoy something more.
