'An ambitious and successful demonstration of the markedly different ways the medieval canon law of marriage was put into practice. Based on a command of archival evidence, it makes an important contribution to European legal and social history.' R. H. Helmholz, University of Chicago
'Müller would have written a more coherent and tightly argued book if he had confined himself to his abundantly documented Northern European case studies. By pushing his analysis southward, however, he wrote a more captivating and stimulating one. The result of his ambition is a sprawling and learned overview of the varied experiences, judicial and penitential, of sacramental marriage in Western Europe over a period of three centuries.' André Vitória, Speculum
'The book is packed with information and new ideas that everyone who researches medieval canon law must now grapple with.' Anders Winroth, Rezensionen im Deutschen
