Although this book's subtitle is "The Telescope and the Mirror", there is very little discussion on the technical evolution and actual uses of these devices. Instead, the author focuses on the myths and legends about "magic mirrors" allowing the ancients to see what people were doing a great many miles away. The evolution of such myths over the centuries is also discussed, culminating with the invention of a real telescope, knowledge of which eventually reached Galileo. This is indeed a scholarly work. It is focused and heavily annotated, i.e., 166 pages of main text are supported by 50 pages of notes/references. However, scholarly works that are also aimed at general readers should be written in a style that is accessible, friendly and engaging. In my view, this is where this book misses the mark. Although I found the writing style to be authoritative, I also found it to be rather dry and awkward, due in no small part to the many very long-winded and often complex sentences. Consequently, it is very difficult to say what the book's target audience is. In my opinion, this is a work that should be studied rather than simply read for pleasure. It would likely be of interest to scholars who may be involved in research along related topics. However, I suspect that general readers, and even many history buffs like me, may find the book confusing and rather boring.
