Robert Lowell in the context of "Jean Racine"

Accentual-syllabic verse is an extension of accentual verse which fixes both the number of stresses and syllables within a line or stanza. Accentual-syllabic verse is highly regular and therefore easily scannable. Usually, either one metrical foot, or a specific pattern of metrical feet, is used throughout the entire poem; thus one can speak about a poem being in, for example, iambic pentameter. Poets naturally vary the rhythm of their lines, using devices such as inversion, elision, masculine and feminine endings, the caesura, using secondary stress, the addition of extra-metrical syllables, or the omission of syllables, the substitution of one foot for another.

Accentual-syllabic verse dominated literary poetry in English from Chaucer's day until the 19th century, when the freer approach to meter championed by poets such as Samuel Taylor Coleridge and Ralph Waldo Emerson and the radically experimental verse of Gerard Manley Hopkins and Walt Whitman began to challenge its dominance. In the early 20th century, accentual-syllabic verse was largely supplanted by free verse in literary poetry through the efforts of Modernists such as Ezra Pound and Amy Lowell. Nonetheless, some poets, such as Robert Frost, W. H. Auden, Keith Douglas, Robert Lowell, Philip Larkin, Howard Nemerov, James Merrill, Derek Walcott, Geoffrey Hill, Seamus Heaney and Derek Mahon continued to work (though not exclusively) in accentual-syllabic meters throughout the century.

Seamus Justin Heaney MRIA (13 April 1939 – 30 August 2013) was an Irish poet, playwright and translator. He received the 1995 Nobel Prize in Literature. Among his best-known works is Death of a Naturalist (1966), his first major published volume. American poet Robert Lowell described him as "the most important Irish poet since Yeats", and many others, including the academic John Sutherland, have said that he was "the greatest poet of our age". Robert Pinsky has stated that "with his wonderful gift of eye and ear Heaney has the gift of the story-teller." Upon his death in 2013, The Independent described him as "probably the best-known poet in the world".

Heaney was born in the townland of Tamniaran, near Castledawson, Northern Ireland. His family moved to nearby Bellaghy when he was a boy. He became a lecturer at St. Joseph's College in Belfast in the early 1960s, after attending Queen's University, and began to publish poetry. He lived in Sandymount, Dublin, from 1976 until his death. He lived part-time in the United States from 1981 to 2006. He was a professor at Harvard from 1981 to 1997, and their Poet in Residence from 1988 to 2006. From 1989 to 1994, he was also the Professor of Poetry at Oxford. In 1996 he was made a Commandeur of the Ordre des Arts et des Lettres and in 1998 was bestowed the title Saoi of Aosdána. He received numerous prestigious awards.

Sylvia Plath (/plæθ/; October 27, 1932 – February 11, 1963) was an American poet and author. She is credited with advancing the genre of confessional poetry and is best known for The Colossus and Other Poems (1960), Ariel (1965), and The Bell Jar (1963), a semi-autobiographical novel published one month before her suicide. The Collected Poems was published in 1981, which included previously unpublished works. For this collection Plath was awarded a Pulitzer Prize for Poetry in 1982, making her the fourth person to receive this honor posthumously.

Born in Boston, Massachusetts, Plath graduated from Smith College in Northampton, Massachusetts and then the University of Cambridge in England, where she was a Fulbright student at Newnham College. In 1959, Plath took a creative writing seminar with Robert Lowell at Boston University, alongside poets Anne Sexton and George Starbuck. She married fellow poet Ted Hughes in 1956 in London. In 1957, they briefly moved to the United States, but moved back to England in winter 1959. Their relationship was tumultuous and, in her letters, Plath alleges abuse at his hands. They had two children, Frieda and Nicholas, before separating in 1962.

Anactoria (or Anaktoria; Ancient Greek: Ἀνακτορία) is a woman mentioned in the work of the ancient Greek poet Sappho. Sappho, who wrote in the late seventh and early sixth centuries BCE, names Anactoria as the object of her desire in a poem numbered as fragment 16. Another of her poems, fragment 31, is traditionally called the "Ode to Anactoria", although no name appears in it. As portrayed by Sappho, Anactoria is likely to have been an aristocratic follower of hers, of marriageable age. It is possible that fragment 16 was written in connection with her wedding to an unknown man. The name "Anactoria" has also been argued to have been a pseudonym, perhaps of a woman named Anagora from Miletus, or an archetypal creation of Sappho's imagination.

The English poet Algernon Charles Swinburne's "Anactoria" was published in his 1866 collection, Poems and Ballads. "Anactoria" is written from the point of view of Sappho, who addresses the title character in a long monologue written in rhyming couplets of iambic pentameter. The monologue expresses Sappho's lust for her in sexually explicit terms; she first rejects art and the gods for Anactoria's love before reversing her stance and claiming to reject Anactoria in favour of poetry. Swinburne's poem created a sensation by openly approaching then-taboo topics such as lesbianism and dystheism. Anactoria later featured in an 1896 play by H. V. Sutherland and in the 1961 poetic series "Three Letters to Anaktoria" by Robert Lowell, in which an unnamed man loves her before transferring, unrequitedly, his affections to Sappho.
