"A faun carrying an umbrella; a hobbit who lives in a hole; a mysterious name - Lyra; an ill-treated schoolboy with a scar and a secret. Children's fantasies may be said in some sense to begin with resonant images - certainly they often do so in the authors' myths of origins. However, they also begin in an author's reading practices, in his or her own experiences, in the influences which, acknowledged or not, shape and articulate their own vision and help define what it is and, sometimes more importantly, what it is not."
That's the opening of the chapter 'The magical Middle Ages in children's fantasy literature' by David Clark, from Magical Tales: Myth, Legend and Enchantment in Children's Books, a book which I am finding quite fascinating and which is leading me off down all sorts of highways and byeways, remembering books and stories I read as a child, discovering others I haven't read yet and very much want to; it's a many-branched signpost, and it provides a clear illustration - if one were needed - of the cross-pollination of ideas, of how an 'old story' can by re-interpretation become something new, and of how the chain of influence and inspiration stretches from folklore, myth and legend, through the earliest written literature to that of the present day.
