Vansittart's great achievement is to take us into the completely different way of thinking of the men and women of those times; their superstitions and certainties, their rituals and fetishes and taboos. As he pointed out in an essay heralding his aims in the novel, even such primary things as colour had different meanings for them which were ‘bewilderingly complex; the medievals gave each colour heraldic, moral, magical, religious, strategic meanings, often contradictory’. With quick, deft imagery he conjures up not how things might seem to us from the distance of our own time, but how they would have been seen then. The effect is unusual and arresting; he is so swift-footed, his prose so teeming with curious detail, that we want constantly to stop and reflect on what we are reading.
