I read a lot of history books and I am a big fan of books dealing with the history of science and economics. Yet, I could not bring myself to finish this gargantuan book. Before you buy this book be aware that it was written in 1841, and in my opinion it did not age very well. If you are a casual reader of history books, this book is probably not for you.
Of the book's 740 pages, the first 100 or so deal with economic bubbles - these initial chapters are relatively engaging and easy to read. In comparison, the following 150 page are simply a LIST of famous alchemists, with a few brief anecdotes about each one. The other subjects covered later on, prophecies, fortunes telling etc. suffer from the same problem. The book contains no analysis, it merely offers a collection of anecdotes, some amusing some not.
The book is written in archaic language, with Latin and French phrases interspersed throughout it. Occasionally, entire Latin paragraphs are used with no English translation. I read a lot, and this is the first book in many years that I was not able to finish.
There is one positive thing I can say about this book: it is a fascinating example of 19th century writing. The approach to the subject matter, the narrative tone and the language used were very instructive and interesting for me. Nevertheless, I was only able to make it to page 323 before giving up. For the casual reader I would suggest more modern books on the topics covered. For example: Tulipomania by Mike Dash is a great book about the Tulip trade Bubble of 1636.
