The origins of medieval architecture

the long version

"This book is the first devoted to the important innovations in architecture that took place in western Europe between the death of Emperor Justinian in 565 A.D. and the tenth century. During this period of transition from late antiquity to the Middle Ages, the Early Christian basilica was transformed in both form and function." "Charles B. McClendon draws on rich documentary evidence and archaeological data to show that the buildings of these three centuries, studied in isolation but rarely together, set substantial precedents for the future of medieval architecture."--Jacket.
