Read via NetGalley. It’s out in August 2024.

This book is highly engaging, thoughtful, sometimes depressing, and overall wonderful.

It’s also occasionally snarky. To whit: “On 19 July 1870 France declared war on Prussia (this was a time when states still officially declared war).”

One of the things that people who have never studied history don’t really think about is just how much we don’t know about the past. And that that lack is not for want of trying, but because the sources simply aren’t available. And that sometimes, that lack isn’t because people in the past didn’t bother to record it, but because the sources have been “lost”. Sometimes “lost” means the sources succumbed to time and the environment; sometimes folks re-used the medium for other purposes (binding other books, or for bullet casings – which makes me weep). And sometimes, as in the focus of this book, they are destroyed when humans destroy archives and libraries during military campaigns. The examples are from France, Ireland, Italy and Germany – he is frank, in the introduction, about the focus being narrowly European and medieval; that’s his area, after all.

The book starts with an overview of how we know what we know – a good reminder for the expert, an easy intro for the novice. It then uses one of the most famous European examples of how narrowly some of our information has avoided being lost: the manuscript of Beowulf, whose story gives me nightmares every time I read it (one manuscript, nearly lost several times… we were THIS CLOSE to not having Grendel and Grendel’s mother and MY GOODNESS imagine how different European literature would be).

The meat of the book is in four chapters that focus on four specific case studies – four instances of the military destroying archives or libraries. In two cases, Bartlett focuses on one significant object that was lost in the destruction, as a specific example of what we used to have; in the other two, he focuses on the entire oeuvre that was destroyed, and what that means for our knowledge of an era. So each chapter has an explanation of why folks were fighting, and why the specific place (Dublin, Chartres) was affected; then discusses what was in the library/archive – how and when it was made, why it was important, how it got to be in that place. And then the process of destruction (being blown up from the inside; bombs dropping from above).

All of that is what I expected from the title, and the overview. What I had overlooked is that the subtitle also says “and Survival”. So each chapter also includes how scholars tried to save the information otherwise lost: finding examples of transcripts, lithographs, and photographs of the now-destroyed work; finding copies of letters and so on in other archives; and so on. Within the horror, therefore, at losing an enormous swathe of Irish medieval history or the largest Mappa Mundi, there is a small amount of joy and gratitude at how people tried to mitigate the loss. And that makes me very thankful.

This is an excellent book for the reader who has a keen interest in medieval history; for those interested in the construction of knowledge; and for those with a broad general interest in history. I loved it.
