Never heard of Benin... and after reading the article, I "knew": lost without trace, great culture, great wealth and great security for all its people..., great artists. And in the end - destroyed by the Britains.

Hm ... so after reading Wikipedia, I knew, it is not lost without trace, but the great Kingdom of Benin was also the great capital of slave trade, with human sacrifices(in the end about 23 a day) and all in all a deep despotic society, etc.

But the artists are indeed great.
