Book excerpt: In diversity, connectedness. This is the surprising thread that emerges when admiring art around the world. Take masks -- in all their raw and exuberant beauty. Art enthusiast Garth Dahl has collected masks on his travels to other countries, attracted first by the beautiful designs and later by the fascinating mythology and cultural history behind the faces. In this book, Dahl presents 74 works from his personal collection, introducing their geographic origins, cultural history and underlying mythology. The vivid colour photographs are by Alistair Eagle.
