This is a fantastic book, detailing how agriculture architecture, and building were revolutionized during the Middle Ages, and dispelling the myths of "The Dark Ages" and loss of technology for the 500 years after the fall of the Roman Empire. Anyone interested in the Middle Ages, SCA, or Renaissance Festivals should read this book. ( )

Changed how I thought about a lot of things. The overview of how agriculture and animal husbandry changed in the Middle Ages was a complete eye opener. In particular, the example of how the ancient world didn't know how to efficiently harness a horse was fascinating. Definitely want to go read his other books. ( )

This is an 1976 book recently reissued in paperback; when first published it was one of the few sources for information about medieval technology (the only other one I can think of is Lynn White’s Medieval Technology and Social Change). However, it’s now sadly dated and a little socially peculiar. Author Jean Gimpel covers medieval energy sources (wind and water mills), mining, farming (the horse collar, the wheeled plow, and horseshoes), and clocks – this is adequate but mostly already discussed by White. The discussion of cathedral building is disappointing, because Gimpel is more interested in cathedral design and the handling of skilled labor than the actual construction of cathedrals – these are interesting topics but not what I was looking for. Finally, the last chapter is a very strange discursus comparing medieval France with 1970s America – predicting the collapse of America due to the limitation of free enterprise, the collapse of the entrepreneurial spirit, overextension of higher education, and resistance to technological innovation. Now what place does that have in a book on medieval technology – despite being prescient and apparently true? ( )

A book that has a great deal to say about the advances in technology in Western Europe until 1400 CE. Quite insightful about that. However, in the last chapter he descends to make some forecasts about the future of technological advance, and the totality of the book suffers. One must remember that the copyright date was 1976, and things have not made many of his predictions brilliant. But for facts, some arresting charts and the strictly medieval portion of the book, still a valuable read. ( )

OK, so you have to be warned that Gimpel starts off by making a huge error that really, any trained historian should know better: he tries to predict the future. & declares that (speaking in 1976), the West has invented pretty much everything that it will, it's all decline from here on out, no more technical innovation for us.

Really: how many of our forebears had any idea what was coming next? The Black Death came seemingly out of nowhere; ditto for many of us (including Gimpel), the Information Age.

Now, if you can get past that, the rest of the book is brilliant. It's a technical/technological history, but that's a tale that can't be told without talking about the technicians, so it's also a social history. The innovation was funded by capital, so there's some banking history. Innovation is frequently adapted for combat, so there's some military history. It's a small book with a very broad scope.

Does that mean there's a little lacking in depth? Possibly: Gimpel himself regrets that there is not more attention paid to the history of engineering, & seems to be deliberately attempting to kickstart such a discipline.

Overall, a very worthwhile book for anyone interested in the Middle Ages, or any fan of the Renaissance willing to have a few of their bubbles burst. ( )
