He does not have a twenty-first-century head. Many characters in historical novels are us, with our point of view, wearing fancy dress. Votan’s dress is rarely fancy. The conceit that all protagonists in historical novels should share our values, our prejudices and our desires is a fine one (I’ve used it myself), and it is much more difficult and much more of an adventure to create characters who are not us, do not believe what we believe, but see things in a way that is alien to us and to our time.
