A concise but illuminating examination of the period's advanced hydraulic engineering... Writing in a scholarly yet graceful and nearly literary style, Magnusson brings a niche topic to life and her treatment is refreshingly devoid of verbosity, a common fault of books of this type. Instead, what comes through is an engaging, intelligent story and study of a fundamental technical challenge that we still struggle with, albeit in different ways, 700 to 800 years later. Civil Engineering Well-written and well-organized... Throughout, [Magnusson's] documentation is careful and substantial, and she does a fine job of placing the history of water technology securely within its economic, social, and political context. -- William H. TeBrake H-France The particular value of this book lies in the convincing way Magnusson describes how medieval water systems functioned in differing social situations; the technological history is framed by general history very skillfully. -- Petra J. E. M. van Dam Technology and Culture A detailed look at gravity-flow water systems... Magnusson weaves together a wealth of information otherwise available only in scattered regional and archaeological studies. -- Charles W. Clark History: Reviews of New Books A richly interesting book on an unlikely topic. Virginia Quarterly Review A well-written and carefully structured account of the provision of the medieval water supply. -- Christopher Allmand Historian An admirably comprehensive and systematic summary of the technology of medieval water systems. Journal of Interdisciplinary History A fascinating introduction to the study of medieval complex water delivery systems. -- Thomas F. Glick Speculum
