It's brilliant, and the skills and craftsmanship of people 40,000 years ago with the most primitive of tools left me slightly freaked out. These were NOT primitive people. These were sophisticated, intelligent, skilful, artistic human beings.
Not only were they able to craft amazingly beautiful and evocative pieces of art, but they also came up with some amazing bits of engineering. There is a doll with moving limbs. There is the use of levers to increase the effectiveness of their spears when hunting. There were cave drawings that behaved like movies in flickering firelight.
So I'm really not sure why the British Museum thought these amazing accomplishments were in any need of modern art to jazz them up.
If that was the intent, then I'm pretty sure they've failed - all that it has made me think is that the now-famous modern artists like Moore, Mondrian and Matisse are just a bunch of derivative copiers.
It's also amazing to think that the finest artists using techniques developed over thousands of years have failed to find a way of recapturing motion in painting that cavemen in front of a flickering fire could manage. We needed to get motion pictures before we finally outdid that.
But the most powerful emotion that gripped me was a creeping sense of fear and of wonder: what happened 40,000 years ago that turned us from apes into fully-fledged humans with such incredible talents apparently overnight? That question remains unanswered and still haunts me powerfully.
Unusually for art, it left me questioning the very essence and origin of humanity. It is quite possibly the most powerful art I've ever seen.
