In this second volume of his authoritative history of the region, Christoph Baumer explores the unique flow of goods, peoples and ideas along the dusty tracks and wandering caravan routes that brought European and Mediterranean orbits into contact with Asia. It is difficult to fault this remarkable volume. The publishers have created a book of quality with stunning illustrations and lucid maps. It will, I believe, become a standard reference for all who study the complex history of Central Asia and the Silk Road.
