Being rather ignorant on this subject, I don't know how this book compares to what else is out there. At first it was not terribly engaging, but I felt I was learning so read further. As it continued through the ages it got better and better, and I appreciated and saw much more in familiar pieces of art. I found the piece on Giotto's 'The Lamentation' very illuminating, but one of my favourites was Donatello's 'Judith and Holofernes' with a rear view of the piece that I have never seen anywhere else. Reading Cole's analysis and seeing nothing more of Judith and the sword than would distinguish her from any other figure of death, the only part of her victim visible being his legs emerging from under her cloak and hanging limply off the pedestal, was incredibly powerful.
