Poetic forms: the villanelle

https://www.poets.org/poetsorg/text/villanelle-poetic-form

“Contemporary poets have not limited themselves to the pastoral themes originally expressed by the free-form villanelles of the Renaissance, and have loosened the fixed form to allow variations on the refrains. Elizabeth Bishop’s “One Art” is another well-known example; other poets who have penned villanelles include W. H. Auden, Oscar Wilde, Seamus Heaney, David Shapiro, and Sylvia Plath.”
