The art world loves hype. Works are touted as the biggest, the rarest, the most expensive. But even in this age of superlatives, the British Museum in London has something special — the oldest figurative art in the world. The artworks on display in the new exhibition Ice Age Art are so old that many are carved from the tusks of woolly mammoths. Made between 40,000 and 10,000 years ago, they are carved from bones, tusks and antlers and depict animals such as bison and lions, as well as human figures. The show, subtitled “arrival of the modern mind” explores the moment human brains began to embrace abstraction, symbolism and imagination.
