"The world spinning. AUTHOR'S NOTE PHILIPPE PETIT WALKED A TIGHTROPE WIRE between the World Trade Center towers on August 7, 1974. I have used his walk in this novel, but all the other events and characters in this work are fictional. I have taken liberties with Petit's walk, while trying to remain true to the texture of the moment and its surroundings. Readers interested in Petit's walk should go to his book To Reach the Clouds (Faber and Faber, 2002) for an intimate account. The photograph used on page 237 is by Vic DeLuca, Rex Images, August 7, 1974, copyright Rex USA. To both of these artists I'm deeply indebted. The title of this book comes from the Alfred, Lord Tennyson poem "Locksley Hall." That in turn was heavily influenced by the "Mu'allaqat," or the "Suspended Poems," seven long Arabic poems written in the sixth century. Tennyson's poem mentions "pilots of the purple twilight dropping down with costly bales," and the "Mu'allaqat" asks, "Is there any hope that this desolation can bring me solace?" Literature can remind us that not all life is already written down: there are still so many stories to be told."
