This is a delightful, no-nonsense conversation about, oddly enough, what medieval history is. Arnold's voice is incredibly conversational, easy to understand, and funny, which is a delight in any book, especially scholarly ones. Each chapter starts with a little vignette of some sort that he continues as an illustration of his point, which makes all of the chapters really easy to follow. And the last chapter, his justification of being a medievalist, is so good I'm going to retype some of it for you:
"Around the time I began writing this book, we had some wood delivered in order to make book shelves. As I helped the delivery man unload the timber, he asked me what I did for a living. 'Medieval history,' I said. 'Oh,' he replied. 'Right....Much call for that, is there?'
"Despite his doubtful tone, the question rather pleased me. It implied the possibility of an artisanal approach to studying the middle ages--a jobbing medieval historian called in to fix a particular kind of problem, implicitly standing alongside other skilled trades." (p. 119)
If you're at all curious about the topic, read this. It's very good.
