Pan's Labyrinth?

Question

My brother and I both remember it as a book before it was a movie, for example the skinny beast thing at the feast, when she looks up and sees the paintings of it eating the babies, I remember the book explaining that, and the feast and why it was all tinted red.

Also I remember the girl enchanted with fairytails learning that she was a moon princess, and the book describing the fawn as being tall, which at the time perplexed me since I had always thought of fawns as being rather short.

The entire movie was so firmiliar, and it seemed to hint at more than it could show, like additional stories from the little girl and the paintings on the ceiling of the feast room.

I have tried a few searches, but it does not give credit to a book that it was baised upon, (that I could find)
Please I know that I read this book, what was its original title?

Answer 1

The movie is from an original screenplay by the director, Guillermo Del Toro. From the Wikipedia page:

In 2004 Del Toro said: "Pan is an original story. Some of my favorite writers (Borges, Blackwood, Machen, Dunsany) have explored the figure of the god Pan and the symbol of the labyrinth. These are things that I find very compelling (remember the labyrinth image on Hellboy?) and I am trying to mix them and play with them." Some of the works he drew on for inspiration include Jorge Luis Borges' Labyrinths, Arthur Machen's The Great God Pan and The White People, Lord Dunsany's The Blessing of Pan, Algernon Blackwood's Pan's Garden and Francisco Goya's Saturn Devouring His Son.

Perhaps you've read some of the same books as Del Toro?
