Yesterday, I visited the "Schädelkult" (= Skull cult) exhibition in Herne. I noticed the flyer (purple! with a skull!) at the Sea Life and since the exhibition will close at 14.4.2013, we went this weekend. The entry is free this and the next weekend, so if I made you curious, just go ahead and see the skulls for yourself!
The exhibition is centred about skulls and what they mean to different cultures. A very Gothic topic, as many of the cults were centered around getting in touch with death - your own or your beloved ones. They show crystal skulls (a replicate as all the ones that were attributed to the Maya), sugar skulls from the Mexican Day of the Dead, shrunken heads, carved skulls...
There was even a part of the exhibition dedicated to human skull development, brains and skull deformations that were in fashion during the ages. I personally was not aware, that women around 1000 b.c. formed their head conically to get a longer -fashionable- forehead!
I really liked the exhibition and can only recommend it. And if you go there, bring me some of these great but expensive chairs and Schnaps in skull bottles!
