When I’m traveling, I love finding unexpected connections between people and places and ideas. Like Ekphrasis — an ancient Greek thing that I learned about in Mexico for an event sponsored by Americans. (If, like most people, you haven’t been following along, I’m an American in Greece on my way back to Mexico). Ekphrasis is a literary work that’s about or inspired by a piece of art. Like everything Greek, the idea of ekphrasis goes deeper than that. But to keep things simple, Dan Brown’s The Da Vinci Code is ekphrasic because the story is built around Leonardo’s paintings, including “Vitruvian Man.” John Keats’ poem, “Ode on A Grecian Urn” is also ekphrasic.
