Firstly, it's probably important to say it's hard for me to make a judgment on the thesis of this book since I am, of course, not a historian. The basic premise is that Isidore's Etymologiae had made its way across Europe, all the way to the British Isles, to inform the education and literary culture that can be seen most clearly in the Exeter Book of Riddles. Salvador-Bello suggests that the riddles in this collection were much more than silly games and were a legitimate mode of education in the style of an encyclopedia.

I can say for sure this was a very fun read. Salvador-Bello stars with a general history of literacy and education in Europe and England, and then goes through the Exeter Book riddle by riddle, cross-referencing directly to the Etymologiae and other European engimata, comparing the wording and composition.

Regardless of the actual thesis, I think this book makes a great read for anyone interested in the Exeter Book of Riddles or Anglo-Saxon England. Every single riddle is placed in context and broken down, with all possible solutions posited and explained alongside Salvador-Bello's own theories. There is plenty of space to make your own judgments. I had no idea about the Etymologiae before I found this book and what a lovely text it is. How fun it is to see the medieval mind try to make sense of the world. Isidore explains that the barnacle goose lays barnacles (which are actually eggs) and effs off and dies; this was their way of explaining migration seasons because they had no clue where these birds went and how they returned.
