Notes on Ekphrasis by Alfred Corn

" ... The result is then not merely a verbal 'photocopy' of the original painting, sculpture, or photograph, but instead a grounded instance of seeing, shaped by forces outside the artwork. In such poems, description of the original work remains partial, but authors add to it aspects drawn from their own experience - the fact, reflections, and feelings that arise at the confluence of a work of visual art and the life of the poet."
