I am currently undergoing research for my Fine Art dissertation which is about the definition of architectural style in Medieval Iberia. I have read near 30 books and articles on the subject and I have to say, this is perhaps the best I have found. It is rare for such a diverse topic to be written so well - most books tend to fall into the category of coffee-table book meets guidebook, but this is insightful and genuinely interesting. I have to admit to skim-reading it as it is largely a history book rather than an art-history book, but it has provided me with a fantastic understanding of the time period, as well as conveying a better grasp of what the social relationships of the time were actually like. So often art historians assume Muslim and Christian rulers were constantly at war, but in actual fact, they often formed strong alliances in order to vanquish a shared enemy. A very insightful book, I strongly recommend it to anyone else studying this time period.
