Modern sonnet
With the advent of free verse, the sonnet came to be seen as somewhat old-fashioned and fell out of use for a time among some schools of poets.[citation needed] However, a number of modern poets, including Wilfred Owen, John Berryman, George Meredith, Edwin Morgan, Robert Frost, Rupert Brooke, George Sterling, Edna St. Vincent Millay, Federico García Lorca, E.E. Cummings, Jorge Luis Borges, Pablo Neruda, Robert Lowell, Joan Brossa, Vikram Seth, Rainer Maria Rilke, Jan Kal, Ernest Hilbert, Kim Addonizio, and Seamus Heaney continued to use the form. Elizabeth Bishop's inverted "Sonnet" was one of her last poems. Ted Berrigan's book, THE SONNETS, is an arresting and curious take on the form. Paul Muldoon often experiments with 14 lines and sonnet rhymes, though without regular sonnet meter. The advent of the New Formalism movement in the United States has also contributed to contemporary interest in the sonnet.
