It’s perhaps a stretch to consider Spanish history “Asian”. Yet a large portion of what we now call Spain, and for at least a couple centuries most of it, was part of the Muslim world, with a dynasty whose founder was the last remaining scion of the overthrown Umayyad dynasty in Damascus. Europe, Asia, East and West had, if they were defined at all, rather different meanings in the Middle Ages than than they do today.

William Atkins has done extensive and presumably rather expensive research for The Immeasurable World. He writes from first hand experience of visiting eight deserts as diverse as the empty quarter of Oman and the famous Burning Man Festival in the United States. Each gets an extended essay with similar components. So, no rides for days on end with just a camel for a friend, but Atkins, to his credit, does manage at each of the deserts he visits to get some sand in his shoes and some camel hair in his oatmeal porridge.
