The idea that a poem is like a picture has been a commonplace since at least ancient Greece, and writers and artists have frequently discussed poetry by discussing painting, and vice versa, but their efforts raise more questions than they answer. From Plutarch ("painting is mute poetry, poetry a speaking picture") to Horace ("as a picture, so a poem"), apparent clarity quickly leads to confusion about, for example, what qualities of pictures are being urged upon poets or how pictorial properties can be converted into poetical ones.
The history of comparing and contrasting painting and poetry turns out to be partly a story of attempts to promote one medium at the expense of the other. At the same time, analogies between word and image have enabled writers and painters to think about and practice their craft. Ultimately, Barkan argues, this dialogue is an expression of desire: the painter longs for the rich signification of language while the poet yearns for the direct sensuousness of painting.
