Let’s start with Tolstoy’s War and Peace. I wouldn’t normally think of it as a historical novel – why did you choose to put it on your list?

Partly because it’s one of my favourite books of all time and partly because I think it counts as a historical novel in my definition, which is very broad and is simply a novel that shows people’s lives from an earlier time. I don’t like the idea of containing historical fiction in this genre ghetto where you are sort of writing for the women’s market and you’ve got a lot of patronising. I love this idea that Tolstoy is telling this story from the past and meditating on what he thinks the nature of history is about. His idea is that it is very much an accident that things happen, and there are these small things – someone is in a bad mood at the time – that have vast repercussions across people’s lives. I love that. There are these Napoleon figures, these very vulgar kind of post-revolutionary French figures who are destroying the old Europe and who are mixed up with our heroes and heroines living their lives. I think it’s the most amazing mixture.

It’s told from the perspective of five aristocratic families: do these different points of view make it more accessible?

Yes, absolutely. It’s a panorama and you see everything from these epic battle scenes to a magical sleigh ride at night in the snow, which was the most beautiful and lyrical passage. You do have the sense of the whole of society interacting as they fall in love or their fortunes change because of the war; you see things on a big scale as well as a small scale at the same time. 

Let’s move on to The Name of the Rose by Umberto Eco.

I read this a few years ago and it was one of those books you always remember because it creates a whole new way of thinking. I had no idea at the time that the medieval mindset was any different to the modern one. It is about the adventure of a Franciscan friar and his novice in medieval Italy and it is part murder mystery, part game with semiotics and medieval knowledge. At university I read lots of French books referring to this medieval period where all knowledge was supposed to be classified, and re-classified and super-classified, and it became sort of idiotic, this academic approach that these monks had. Yet there was something amazing about this belief that you could classify knowledge. It’s also very good storytelling, but the part I remember was the sort of library filled with knowledge and these games, which teased you with knowing things and not knowing things. It’s just this very complex mindset that’s really different from our own and because I knew nothing about it, it was just terribly exciting to be taken off into this world.

This book seems to appeal to a very wide variety of people from mathematicians and science-fiction enthusiasts to linguists and literature professors…

I must say that I have tried to read a couple of other books by Umberto Eco and found them quite difficult, so I think he was reaching out to the world of fiction. There was an interesting book that I read recently by him about art and beauty in the Middle Ages, but it was so much more an academic book. I think The Name of the Rose crosses boundaries in a way that others don’t. 

Let’s go on to the next book, An Instance of the Fingerpost by Iain Pears.

This one is really complicated – maybe I just like them complicated. Pears is also a really intelligent man and has oscillated between writing fiction for entertainment and academics. He’s lived in Italy and he’s a professor and this book sort of speaks to all of those things. On the face of it, it’s about a murder in 17th-century Oxford, but quite amazing things are going on that are creepy yet fascinating. There were things I hadn’t thought about before like body-stealing to learn dissections and anatomy. There is a lot about this rudimentary science, well, rudimentary to us but very exciting and magical to them. The first part of the book is told by one character and you feel you’ve learned the story. You get to the next part and it’s one of the other characters telling the same story but from his point of view and it’s really different. There are four characters who each tell it and each time you learn something new. Then you’re thinking it’s a clever game, but with the final story it suddenly becomes something different. I don’t want to give the story away but it’s a very moving and strange story with these religious overtones and it’s just amazing. It really blows you away.

As a reader you tend to trust your narrator, so how does having four affect the way you’re reading the story?

I think it is reinforcing the way that the boundaries were being shifted at the time and that knowledge was expanding. You’re looking at the cadaver from different points of view and then looking at the story from different points of view too. It all fits together very beautifully. Then there’s the shock of something else.
