Gregory is right is not an 'easy' read. I have found it to be an invaluable Tarot resource. I'm no expert, but I do not think it would hurt anyone who is studying/learning the Tarot to read 'Bohemians'.
I have read on here that Arthur E.Waite did the translation from French to English for this book and this pretty much explains why it may be hard to read. Waites' 'Pictorial Key' is a must read in my humble opinion, but his style is not of an easy flowing prose type.
I surmize I feel it is the best book on Tarot, because I come to the Tarot with a Rosicrucian type of vision and I feel it was the the first 'respected' book written about Tarot (maybe this is wrong??? I don't know). I would choose this book without a doubt over the Waite or Crowley books, but that it just my single opinion.... read them all and decide for yourself (s).
Here you can read 'Tarot of the Bohemians' online:
