Ekphrasis

E K P H R A S I S is a rhetorical device, in which one medium of art relates to another medium by describing its essence and form, and in
doing so, connects more directly to the audience. A descriptive work of prose or poetry may thus highlight what is shown in any of the visual arts, enhancing the original art and taking on a life of its own through its
description. Virtually any type of artistic media may be the actor of, or subject of ekphrasis. In this way, a poem may re-present a painting, or vice versa. *

In this book there are eight poems about the author's previously completed oil and watercolor paintings, a pencil sketch about one poem, and a watercolor sketch about another poem.
