Was introduced to the author of this book from a Lucy Worsley BBC documentary.
It is a very good social history of the development of lighting and its extent and economics. It is UK centric with examples from National Trust properties. It is very interesting and gives a totally different view than one obtained from films and historical novels. The total ignoring of the economics of lighting, especially of the use of numerous candles and their type in most fictional productions distorts the general view of history.
It could of used additional drawn illustrations, perhaps patent application drawings, or new ones instead of the photo illustrations. I found the photo illustrations hard to extract any hard information from. Some additional hard data, say from great house account books, would also improve its usefulness as history.
