I used this book for the illustrations in my thesis on Blake. Although they are not in color, the sharp, black lines of the drawings accentuate a side of Blake that is often overlooked. That being his obstinate adherence to the "True Style of Art. The Art of Invention Not of Imitation." The Art of the "straight & wirey bounding line." All of the illuminated books are included in this volume, with commentary on each plate. This is an excellent book for the burgeoning Blake scholar. In fact, I used this book to make a photocopy of plate 10 from America a Prophecy for the tatoo I had carved on my right arm. I had the tatoo artist add the color from the Princeton editions of the illuminated books, which are the very best copies of Blake available if you can afford them.
