DM writes concisely, vividly, and evocatively about the terrain, social history, rural customs of this small area of England, which makes for an excellent read. However, if you are looking for an analysis of the archaeological findings of his excavation (how deep is the chalk, etc.) he does not report this information. He does discuss discursively the importance of the horse in pre-history and early history, from the steppe cultures through the Mediterranean cultures, and those of the Celts, which help understanding why the horse image, rather than some other image, adorns this hillside. He speculates on what the creation of this image might have meant to the tribe/s that created it. The book is well-illustrated with color photographs.
