A virtually perfect mesh of history and fiction can be found in the writing of Rosemary Sutcliff. She seems to work from no recipe for mixing fact and imagination and thus, like fantasy, which it also resembles in its magic qualities, her writing defies neat categorization. Still, what cannot be defined can be observed. Thus what one perceives is that Sutcliff begins with a very well stored mind and an affinity for a given period in the distant past that she sets forth as if it were something she herself had once experienced, richly remembers, and recounts—much as some ordinary person talks about the memories of childhood or a trip. Sutcliff easily, unobtrusively, and naturally seems able to supply just the right detail at just the right time to make both setting and plot utterly convincing. Her persuasion is so compelling that readers are imperceptibly led back into the past with such subtlety they feel they are living side by side with her characters. (pp. 163-64)
With her first major novel, The Eagle of the Ninth …, Sutcliff brought a new dimension into historical fiction for children, indeed into children's literature…. [She] gives all her characters universal, human problems while making them vital and recognizable in their own time. And with all this she also tells a great story. (p. 164)
