ekphrasis
If the dialectic of word and image is central to the study of media, then the term ekphrasis (alternatively spelled ecphrasis) must also be a crucial part of understanding media as the intersection of verbal and visual. Few pieces of media jargon have as long a history or as considerable an evolution as ekphrasis. The conflict of word and image in media can be better understood by tracing the history and evolution of ekphrasis, which embodies the practice of both elements.
