Everything is Illuminated

The concept of illumination here is threefold. Figuratively, it means clarification and explanation. Jonathan researches his family in order to illuminate its history. In turn, this research allows him to understand his own life in its broader context. Jonathan reads his own life, at least in part, by the light of past generations.

Cosmically, the "sex light" is a glow produced by couples making love, and it can be seen from outer space. In this context, illumination stands for generation or creation. People burn brightest when they conceive children, because this is the ultimate generative act. In a related way, Jonathan brings things to light for us through his own creativity, his writing. As related aspects of the story come together, the reader feels a touch of enlightenment.

Literally, illumination can mean embellishment, as in illuminated manuscripts. In this novel, fantasy constantly embellishes reality, making everything seem more beautiful or exciting. Alex, Jonathan, and the author illuminate their stories in this way.
