Afghanistan has brought its crown jewels to London, almost. In the British Museum‘s latest breath-stopping display, we are drawn on a journey of wonder into this culturally hybrid world of two thousand years ago. In London we proudly claim what is now the world’s most multi-cultural society, but this ancient crossroads of the Silk Road came close, if only by the conduit of trade and, presumably, artisans. As a result, Greek stylistic influence crossed paths with Chinese, Indian, Roman, Mesopotamian and Central Asian in a feast of artistic cross-fertilisation. Seeing this exhibition is like a whistle-stop tour of all those places.
