By the close of the nineteenth century, many poets had abandoned rhyme and meter in favor of "free verse." Nearly one hundred years later, a growing number of younger poets are reclaiming traditional conventions of prosody by composing rhymed and measured poetry. Missing Measures is the first full articulation of the aesthetics of this new movement. Timothy Steele, one of the best of those poets who are sometimes called the "New Formalists," treats his subject against a backdrop of the long history of ideas about poetry, formulated first by the ancients and re-examined and re-interpreted by subsequent writers. Steele offers a new perspective on the wholesale departure from tradition proclaimed in modernist critical justifications. A rare marriage of clear writing, careful scholarship, and bold thinking, Missing Measures provides a vital new movement with a critical manifesto.
