An interdisciplinary study of the Book of Jonah from theological, hermeneutical, and psychological perspectives. An earlier version of the book was published as The Jonah Complex. Among other subjects, the authors examine the influence of popular philosophy and literature of Hellenism on Jonah, and how Jonah constitutes a bridge between the Greek and Jewish worlds.
This is a great book, not only about the Book of Jonah, but the book is really a good primer for understanding Leviathan mythology.
On a side note: I happened to rewatch 2001: A Space Odyssey about a week after I read this book. The Leviathan symbolism, which I hadn't even known existed, came through crystal clear, which made it much more interesting than the movie already was. Even the ending made sense.
I would also suggest Mircea Eliade's Rites and Symbols of Initiation to help understand the ending of 2001: A Space Odyssey.
