One of things I love most about art is the fluidity of my perception of it: how it affects me can change depending on my mood, where and how I see it, and even with whom I see it. This is what I love about paging through The Art Book: New Edition (Phaidon, $59.95)—it puts art into new perspectives. Rather than listing the artists by period or genre, the book places them alphabetically. This makes for some interesting juxtapositions—a classic medieval work appears right next to a thoroughly modern sculpture, for instance. (For perhaps the ultimate juxtaposition, turn to pages 164-165.) Even familiar iconic pieces look new and different in this context; I can’t remember when an art book was this much fun. I suggest reading it with someone else, so that together you can be surprised by the serendipity of who turns up next to whom. It reminds you that art constantly amazes and can be seen in new and exciting ways.
