An indispensable classic and a thoroughly illustrated introduction to Byzantine art, wide-ranging and literate. Though it focuses on the extraordinary early Christian treasures of Constantinople (including site plans and photographs of mosaics, carving and decoration), the book also includes chapters on Sicily, Venice and Slavonic art of the Balkans. With 250 illustrations, many in color, and accompanying text, it is a compact introduction to the art and architecture of the era.  (TKY22, $16.95)
