One of the three books with similar design (and same introduction, so you only need to read it once if one read all three). Each is a group of 14-15 works of art, with comments and things to ponder from the author. All have Western/Orthodox art (except the one on Saints). They make a quick read, though one might stay pondering on each piece of art, if one wants.
My favorite on this one is: St. John The Baptist Retiring To The Desert (Di Paolo) / The Martyrdom Of St. Agatha (Tiepolo).
Some of the saints presented here are quite popular, some are less known. I like how Beckett puts her experience on certain saints into the comments. Each saint is also given their life-dates.
