By now a classic, it presents in a single volume a coherent overall view of the history and the changing character of Early Christian and Byzantine architecture, from Rome and Milan to North Africa, from Constantinople to Greece and the Balkans, and from Egypt and Jerusalem to the villages and monasteries of Syria, Asia Minor, Armenia, and Mesopotamia.
i just love the fact that the history of any thing and everything has to be connected with the history of art and architecture, it is so much fun to understand it all together.
Very tough read. Although the volume is comprehensive, and the amount of research for it was colossal, I think Krautheimer has a gift to turn exciting things into boring. There are very long descriptions of buildings, like an enormous indistinguishable catalog, and very few stories to accompany the descriptions. Of course, the changes in architecture after the Justinian period are lethargic, pachydermic, so it's hard to make that section into anything fun. More on Cappadocia and Meteora would have been more exciting. The section on Hagia Sophia was amazing, though.
