ekphrasis

Ekphrasis has been considered generally to be a rhetorical device in which one medium of art tries to relate to another medium by defining and describing its essence and form, and in doing so, relate more directly to the audience, through its illuminative liveliness. A descriptive work of prose or poetry, a film, or even a photograph may thus highlight through its rhetorical vividness what is happening, or what is shown in, say, any of the visual arts, and in doing so, may enhance the original art and so take on a life of its own through its brilliant description. One example is a painting of a sculpture: the painting is “telling the story of” the sculpture, and so becoming a storyteller, as well as a story (work of art) itself. Virtually any type of artistic medium may be the actor of, or subject of ekphrasis. One may not always be able, for example, to make an accurate sculpture of a book to retell the story in an authentic way; yet if it’s the spirit of the book that we are more concerned about, it certainly can be conveyed by virtually any medium and thereby enhance the artistic impact of the original book through synergy.
