I like Caravaggio but there is no saving this little guide. Its so badly done, all the most interesting pictures are spread across two pages so you lose most of them in the fold, unless you crack the spine and even then its hard to see the full picture. The text is even worse, full of typos and grammatical errors, but so badly written whole pages make no sense. I found I was re-reading something for sense on every page and in the end gave up to skim read which was less painful.
If that wasn't bad enough the interpretations of elements of the paintings were gibberish.
