After all of the positive reviews, I was fairly disappointed by the book. The review of the technology is fairly general and not very specific. For example, brick composition percentages, firing temperatures, bond patterns, etc. are not discussed very much at all. He talks about Romans sawing bricks, but not what implements they used to saw them nor does the book include any illustrations of such implements from that period. Certainly some must be available from Pompeii.
What is worse is that the illustrations do not seem to be linked to the text. Not only is there no cross-referencing system (i.e. see Fig. 5), but more complicated points are not illustrated, e.g. opus recticulatum, and where there is an accompanying illustration, such as the Temple of Rediculus, the captions do not reflect the text, e.g. 'note the use of red brick highlights and moulded bricks.' Therefore, you must read the text to understand what to look for in the picture. Diagrams of how to lay the bricks to achieve the various designs shown in the photos would have been a great addition.
The photographs are good quality prints. Some have close ups of details. But others, like of the small mausoleum on p. 117, waste good space on the background, resulting in a smaller picture of the building, and do not have a close up of interesting details, in this case the two colour brickwork of the dome. The text often reads like for a guidebook, i.e. building x is noted by its use of y bricks and z patterns. These are great if you are going to visit, but rather weak in the light of limited photography.
