"He writes the words that he was written by."
The idiom 'nature abhors a vacuum' is attributed to Aristotle (as 'horror vacui'). I can understand the feeling, to a degree, because when confronted with a blank wall in someone's house, I feel that it needs a canvas. But, unfortunately for the world of The Unwritten, nature is less choosy about what it fills its vacuum with, including the space left after Tom's encounter with Leviathan.
Aristotle also taught — in his Poetics (c. 335 BC), a philosophical work looking at dramatic theory and its applications — that acts of creation, in its many guises, including storytelling, are fundamentally acts of mimesis, with each act varying by its medium and its manner.
It may seem like I've gone off on a tangent, but I see every part of what's written above as having relevance to the multi-faceted approach that Carey took with the series. Poetics is a short work, but an understanding of the basic principles that Aristotle was postulating will enrich a reading of Orpheus in the Underworld; and, if it's not already apparent, familiarity with the Orpheus myth will help also.
