"All in all, Troianos' overview of Byzantine legal sources has been by far the best book on the subject since the first edition of the work appeared in 1986 [...] In sum, the German translation of Troianos' overview of Byzantine legal sources constitutes the best work to date on this subject and is a must-have for anyone interested in later Roman as well as Byzantine law. Neye and Simon are to be commended for making this invaluable text accessible to a German-reading audience." Zachary Chitwood in: Bryn Mawr Classical Review 2018.03.18
