Emily Elizabeth Dickinson (December 10, 1830 – May 15, 1886) was an American poet. Born in Amherst, Massachusetts, to a successful family with strong community ties, she lived a mostly introverted and reclusive life. After she studied at the Amherst Academy for seven years in her youth, she spent a short time at Mount Holyoke Female Seminary before returning to her family's house in Amherst. Thought of as an eccentric by the locals, she became known for her penchant for white clothing and her reluctance to greet guests or, later in life, even leave her room. Most of her friendships were therefore carried out by correspondence.

Although Dickinson was a prolific private poet, fewer than a dozen of her nearly eighteen hundred poems were published during her lifetime. The work that was published during her lifetime was usually altered significantly by the publishers to fit the conventional poetic rules of the time. Dickinson's poems are unique for the era in which she wrote; they contain short lines, typically lack titles, and often use slant rhyme as well as unconventional capitalization and punctuation. Many of her poems deal with themes of death and immortality, two recurring topics in letters to her friends.

Although most of her acquaintances were probably aware of Dickinson's writing, it was not until after her death in 1886 — when Lavinia, Emily's younger sister, discovered her cache of poems — that the breadth of Dickinson's work became apparent. Her first collection of poetry was published in 1890 by personal acquaintances Thomas Wentworth Higginson and Mabel Loomis Todd, both of whom heavily edited the content. A complete and mostly unaltered collection of her poetry became available for the first time in 1955 when The Poems of Emily Dickinson was published by scholar Thomas H. Johnson. Despite unfavorable reviews and skepticism of her literary prowess during the late 19th and early 20th century, critics now consider Dickinson to be a major American poet.

Emily Elizabeth Dickinson was born at the family's homestead in Amherst, Massachusetts, on December 10, 1830, into a prominent, but not wealthy, family. Two hundred years earlier, the Dickinsons had arrived in the New World — in the Puritan Great Migration — where they prospered. Emily Dickinson's paternal grandfather, Samuel Dickinson, had almost single handedly founded Amherst College. In 1813 he built the homestead, a large mansion on the town's Main Street, that became the focus of Dickinson family life for the better part of a century. Samuel Dickinson's eldest son, Edward, was treasurer of Amherst College for nearly forty years, served numerous terms as a State Legislator, and represented the Hampshire district in the United States Congress. On May 6, 1828, he married Emily Norcross from Monson. They had three children:

• William Austin (1829 – 1895), known as Austin, Aust or Awe;
• Emily Elizabeth; and
• Lavinia Norcross (1833 – 1899), known as Lavinia or Vinnie.

By all accounts, young Emily was a well behaved girl. On an extended visit to Monson when she was two, Emily's Aunt Lavinia described Emily as "perfectly well & contented — She is a very good child & but little trouble." Emily's aunt also noted the girl's affinity for music and her particular talent for the piano, which she called "the moosic".

Dickinson attended primary school in a two story building on Pleasant Street. Her education was "ambitiously classical for a Victorian girl". Her father wanted his children well educated and he followed their progress even while away on business. When Emily was seven, he wrote home, reminding his children to "keep school, and learn, so as to tell me, when I come home, how many new things you have learned". While Emily consistently described her father in a warm manner, her correspondence suggests that her mother was regularly cold and aloof. In a letter to a confidante, Emily wrote she "always ran Home to Awe [Austin] when a child, if anything befell me. He was an awful Mother, but I liked him better than none."

On September 7, 1840, Dickinson and her sister Lavinia started together at Amherst Academy, a former boys' school that had opened to female students just two years earlier. At about the same time, her father purchased a house on North Pleasant Street. Emily's brother Austin later described this large new home as the "mansion" over which he and Emily presided as "lord and lady" while their parents were absent. The house overlooked Amherst's burial ground, described by one local minister as treeless and "forbidding".

Dickinson spent seven years at the Academy, taking classes in English and classical literature, Latin, botany, geology, history, "mental philosophy," and arithmetic. Daniel Taggart Fiske, the school's principal at the time, would later recall that Dickinson was "very bright" and "an excellent scholar, of exemplary deportment, faithful in all school duties". Although she had a few terms off due to illness — the longest of which was in 1845 – 1846, when she was only enrolled for eleven weeks — she enjoyed her strenuous studies, writing to a friend that the Academy was "a very fine school".

Dickinson was troubled from a young age by the "deepening menace" of death, especially the deaths of those who were close to her. When Sophia Holland, her second cousin and a close friend, grew ill from typhus and died in April, 1844, Emily was traumatized. Recalling the incident two years later, Emily wrote that "it seemed to me I should die too if I could not be permitted to watch over her or even look at her face." She became so melancholic that her parents sent her to stay with family in Boston to recover. With her health and spirits restored, she soon returned to Amherst Academy to continue her studies. During this period, she first met people who were to become lifelong friends and correspondents, such as Abiah Root, Abby Wood, Jane Humphrey, and Susan Huntington Gilbert (who later married Emily's brother Austin).

In 1845, a religious revival took place in Amherst, resulting in 46 confessions of faith among Dickinson's peers. Dickinson wrote to a friend the following year: "I never enjoyed such perfect peace and happiness as the short time in which I felt I had found my savior." She went on to say that it was her "greatest pleasure to commune alone with the great God & to feel that he would listen to my prayers." The experience did not last: Dickinson never made a formal declaration of faith and attended services regularly for only a few years. After her church going ended, about 1852, she wrote a poem opening: "Some keep the Sabbath going to Church – / I keep it, staying at Home".

During the last year of her stay at the Academy, Emily became friendly with Leonard Humphrey, its popular new young principal. After finishing her final term at the Academy on August 10, 1847, Dickinson began attending Mary Lyon's Mount Holyoke Female Seminary (which later became Mount Holyoke College) in South Hadley, about ten miles (16 km) from Amherst. She was at the seminary for only ten months. Although she liked the girls at Holyoke, Dickinson made no lasting friendships there. The explanations for her brief stay at Holyoke differ considerably: either she was in poor health, her father wanted to have her at home, she rebelled against the evangelical fervor present at the school, she disliked the discipline minded teachers, or she was simply homesick. Whatever the specific reason for leaving Holyoke, her brother Austin appeared on March 25, 1848, to "bring [her] home at all events". Back in Amherst, Dickinson occupied her time with household activities. She took up baking for the family and enjoyed attending local events and activities in the budding college town.

When she was eighteen, Dickinson's family befriended a young attorney by the name of Benjamin Franklin Newton. According to a letter written by Dickinson after Newton's death, he had been "with my Father two years, before going to Worcester – in pursuing his studies, and was much in our family." Although their relationship was probably not romantic, Newton was a formative influence and would become the second in a series of older men (after Humphrey) that Dickinson referred to, variously, as her tutor, preceptor or master.

Newton likely introduced her to the writings of William Wordsworth, and his gift to her of Ralph Waldo Emerson's first book of collected poems had a liberating effect. She wrote later that he, "whose name my Father's Law Student taught me, has touched the secret Spring". Newton held her in high regard, believing in and recognizing her as a poet. When he was dying of tuberculosis, he wrote to her, saying that he would like to live until she achieved the greatness he foresaw. Biographers believe that Dickinson's statement of 1862 — "When a little Girl, I had a friend, who taught me Immortality – but venturing too near, himself – he never returned" — refers to Newton.

Dickinson was familiar not only with the Bible but also with contemporary popular literature. She was probably influenced by Lydia Maria Child's Letters from New York, another gift from Newton (after reading it, she gushed "This then is a book! And there are more of them!"). Her brother smuggled a copy of Henry Wadsworth Longfellow's Kavanagh into the house for her (because her father might disapprove) and a friend lent her Charlotte Brontë's Jane Eyre in late 1849. Jane Eyre's influence cannot be measured, but when Dickinson acquired her first and only dog, a Newfoundland, she named him "Carlo" after the character St. John Rivers' dog. William Shakespeare was also a potent influence in her life. Referring to his plays, she wrote to one friend "Why clasp any hand but this?" and to another, "Why is any other book needed?"

In early 1850 Dickinson wrote that "Amherst is alive with fun this winter ... Oh, a very great town this is!" Her high spirits soon turned to melancholy after another death. The Amherst Academy principal, Leonard Humphrey, died suddenly of "brain congestion" at age 25. Two years after his death, she revealed to her friend Abiah Root the extent of her depression: "... some of my friends are gone, and some of my friends are sleeping – sleeping the churchyard sleep – the hour of evening is sad – it was once my study hour – my master has gone to rest, and the open leaf of the book, and the scholar at school alone, make the tears come, and I cannot brush them away; I would not if I could, for they are the only tribute I can pay the departed Humphrey".

During the 1850s, Emily's strongest and most affectionate relationship was with Susan Gilbert. Emily eventually sent her over three hundred letters, more than to any other correspondent, over the course of their friendship. Sue was supportive of the poet, playing the role of "most beloved friend, influence, muse, and adviser" whose editorial suggestions Dickinson sometimes followed, Susan played a primary role in Emily's creative processes." Sue married Austin in 1856 after a four year courtship, although their marriage was not a happy one. Edward Dickinson built a house for him and Sue called the Evergreens, which stood on the west side of the Homestead. There is controversy over how to view Emily's friendship with Sue; according to a point of view first promoted by Mabel Loomis Todd, Austin's longtime mistress, Emily's missives typically dealt with demands for Sue's affection and the fear of unrequited admiration. Todd believed that because Sue was often aloof and disagreeable, Emily was continually hurt by what was mostly a tempestuous friendship. However, the notion of a "cruel" Sue — as promoted by her romantic rival — has been questioned, most especially by Sue and Austin's surviving children, with whom Emily was close.

Until 1855, Dickinson had not strayed far from Amherst. That spring, accompanied by her mother and sister, she took one of her longest and farthest trips away from home. First, they spent three weeks in Washington, where her father was representing Massachusetts in Congress. Then they went to Philadelphia for two weeks to visit family. In Philadelphia, she met Charles Wadsworth, a famous minister of the Arch Street Presbyterian Church, with whom she forged a strong friendship which lasted until his death in 1882. Despite only seeing him twice after 1855 (he moved to San Francisco in 1862), she variously referred to him as "my Philadelphia", "my Clergyman", "my dearest earthly friend" and "my Shepherd from 'Little Girl'hood".

From the mid 1850s, Emily's mother became effectively bedridden with various chronic illnesses until her death in 1882. Writing to a friend in summer 1858, Emily said that she would visit if she could leave "home, or mother. I do not go out at all, lest father will come and miss me, or miss some little act, which I might forget, should I run away – Mother is much as usual. I Know not what to hope of her". As her mother continued to decline, Dickinson's domestic responsibilities weighed more heavily upon her and she confined herself within the Homestead. Forty years later, Lavinia stated that because their mother was chronically ill, one of the daughters had to remain always with her. Emily took this role as her own, and "finding the life with her books and nature so congenial, continued to live it".

Withdrawing more and more from the outside world, Emily began in the summer of 1858 what would be her lasting legacy. Reviewing poems she had written previously, she began making clean copies of her work, assembling carefully pieced together manuscript books. The forty fascicles she created from 1858 through 1865 eventually held nearly eight hundred poems. No one was aware of the existence of these books until after her death.

In the late 1850s, the Dickinsons befriended Samuel Bowles, the owner and editor - in - chief of the Springfield Republican, and his wife, Mary. They visited the Dickinsons regularly for years to come. During this time Emily sent him over three dozen letters and nearly fifty poems. Their friendship brought out some of her most intense writing and Bowles published a few of her poems in his journal. It was from 1858 to 1861 that Dickinson is believed to have written a trio of letters that have been called "The Master Letters". These three letters, drafted to an unknown man simply referred to as "Master", continue to be the subject of speculation and contention amongst scholars.

The first half of the 1860s, after she had largely withdrawn from social life, proved to be Dickinson's most productive writing period. Modern scholars and researchers are divided as to the cause for Dickinson's withdrawal and extreme seclusion. While she was diagnosed as having "nervous prostration" by a physician during her lifetime, some today believe she may have suffered from illnesses as various as agoraphobia and epilepsy.

In April 1862, Thomas Wentworth Higginson, a literary critic, radical abolitionist, and ex-minister, wrote a lead piece for The Atlantic Monthly entitled, "Letter to a Young Contributor". Higginson's essay, in which he urged aspiring writers to "charge your style with life", contained practical advice for those wishing to break into print. Dickinson's decision to contact Higginson suggests that by 1862 she was contemplating publication and that it may have become increasingly difficult to write poetry without an audience. Seeking literary guidance that no one close to her could provide, Dickinson sent him a letter which read in full:

Mr Higginson,
Are you too deeply occupied to say if my Verse is alive?
The Mind is so near itself – it cannot see, distinctly – and I have none to ask –
Should you think it breathed – and had you the leisure to tell me, I should feel quick gratitude –
If I make the mistake – that you dared to tell me – would give me sincerer honor – toward you –
I enclose my name – asking you, if you please – Sir – to tell me what is true?
That you will not betray me – it is needless to ask – since Honor is it's [sic] own pawn –

This highly nuanced and largely theatrical letter was unsigned, but she had included her name on a card and enclosed it in an envelope, along with four of her poems. He praised her work but suggested that she delay publishing until she had written longer, being unaware that she had already appeared in print. She assured him that publishing was as foreign to her "as Firmament to Fin", but also proposed that "If fame belonged to me, I could not escape her". Dickinson delighted in dramatic self characterization and mystery in her letters to Higginson. She said of herself, "I am small, like the wren, and my hair is bold, like the chestnut bur, and my eyes like the sherry in the glass that the guest leaves." She stressed her solitary nature, stating that her only real companions were the hills, the sundown, and her dog, Carlo. She also mentioned that whereas her mother did not "care for Thought", her father bought her books, but begged her "not to read them – because he fears they joggle the Mind".

Dickinson valued his advice, going from calling him "Mr. Higginson" to "Dear friend" as well as signing her letters, "Your Gnome" and "Your Scholar". His interest in her work certainly provided great moral support; many years later, Dickinson told Higginson that he had saved her life in 1862. They corresponded until her death, but her difficulty in expressing her literary needs and a reluctance to enter into a cooperative exchange left Higginson nonplussed; he did not press her to publish in subsequent correspondence. Dickinson's own ambivalence on the matter militated against the likelihood of publication. Literary critic Edmund Wilson, in his review of Civil War literature, surmised that "with encouragement, she would certainly have published".

In direct opposition to the immense productivity that she displayed in the early 1860s, Dickinson wrote fewer poems in 1866. Beset with personal loss as well as loss of domestic help, it is possible that Dickinson was too overcome to keep up her previous level of writing. Carlo died during this time after providing sixteen years of companionship; Dickinson never owned another dog. Although the household servant of nine years, Margaret O Brien, had married and left the Homestead that same year, it was not until 1869 that her family brought in a permanent household servant, Margaret Maher, to replace the old one. Emily once again was responsible for chores, including the baking, at which she excelled.

Scholar Judith Farr notes that Dickinson, during her lifetime, "was known more widely as a gardener, perhaps, than as a poet". Dickinson studied botany from the age of nine and, along with her sister, tended the garden at Homestead. During her lifetime, she assembled a collection of pressed plants in a sixty - six page leather bound herbarium. It contained 424 pressed flower specimens that she collected, classified, and labeled using the Linnaean system. The Homestead garden was well known and admired locally in its time. It has not survived, and Dickinson kept no garden notebooks or plant lists, but a clear impression can be formed from the letters and recollections of friends and family. Her niece, Martha Dickinson Bianchi, remembered "carpets of lily - of - the - valley and pansies, platoons of sweetpeas, hyacinths, enough in May to give all the bees of summer dyspepsia. There were ribbons of peony hedges and drifts of daffodils in season, marigolds to distraction — a butterfly utopia". In particular, Dickinson cultivated scented exotic flowers, writing that she "could inhabit the Spice Isles merely by crossing the dining room to the conservatory, where the plants hang in baskets". Dickinson would often send her friends bunches of flowers with verses attached, but "they valued the posy more than the poetry".

On June 16, 1874, while in Boston, Edward Dickinson suffered a stroke and died. When the simple funeral was held in the Homestead's entrance hall, Emily stayed in her room with the door cracked open. Neither did she attend the memorial service on June 28. She wrote to Higginson that her father's "Heart was pure and terrible and I think no other like it exists." A year later, on June 15, 1875, Emily's mother also suffered a stroke, which produced a partial lateral paralysis and impaired memory. Lamenting her mother's increasing physical as well as mental demands, Emily wrote that "Home is so far from Home".

Otis Phillips Lord, an elderly judge on the Massachusetts Supreme Judicial Court from Salem, in 1872 or 1873 became an acquaintance of Dickinson's. After the death of Lord's wife in 1877, his friendship with Dickinson probably became a late life romance, though as their letters were destroyed, this is surmise. Dickinson found a kindred soul in Lord, especially in terms of shared literary interests; the few letters which survived contain multiple quotations of Shakespeare's work, including the plays Othello, Antony and Cleopatra, Hamlet and King Lear. In 1880 he gave her Cowden Clarke's Complete Concordance to Shakespeare (1877). Dickinson wrote that "While others go to Church, I go to mine, for are you not my Church, and have we not a Hymn that no one knows but us?" She referred to him as "My lovely Salem" and they wrote to each other religiously every Sunday. Dickinson looked forward to this day greatly; a surviving fragment of a letter written by her states that "Tuesday is a deeply depressed Day".

After being critically ill for several years, Judge Lord died in March 1884. Dickinson referred to him as "our latest Lost". Two years before this, on April 1, 1882, Dickinson's "Shepherd from 'Little Girl'hood", Charles Wadsworth, also had died after a long illness.

Although she continued to write in her last years, Dickinson stopped editing and organizing her poems. She also exacted a promise from her sister Lavinia to burn her papers. Lavinia, who also never married, remained at the Homestead until her own death in 1899.

The 1880s were a difficult time for the remaining Dickinsons. Irreconcilably alienated from his wife, Austin fell in love in 1882 with Mabel Loomis Todd, an Amherst College faculty wife who had recently moved to the area. Todd never met Dickinson but was intrigued by her, referring to her as "a lady whom the people call the Myth". Austin distanced himself from his family as his affair continued and his wife became sick with grief. Dickinson's mother died on November 14, 1882. Five weeks later, Dickinson wrote "We were never intimate ... while she was our Mother – but Mines in the same Ground meet by tunneling and when she became our Child, the Affection came." The next year, Austin and Sue's third and youngest child, Gilbert — Emily's favorite — died of typhoid fever.

As death succeeded death, Dickinson found her world upended. In the fall of 1884, she wrote that "The Dyings have been too deep for me, and before I could raise my Heart from one, another has come." That summer she had seen "a great darkness coming" and fainted while baking in the kitchen. She remained unconscious late into the night and weeks of ill health followed. On November 30, 1885, her feebleness and other symptoms were so worrying that Austin canceled a trip to Boston. She was confined to her bed for a few months, but managed to send a final burst of letters in the spring. What is thought to be her last letter was sent to her cousins, Louise and Frances Norcross, and simply read: "Little Cousins, Called Back. Emily". On May 15, 1886, after several days of worsening symptoms, Emily Dickinson died at the age of 55. Austin wrote in his diary that "the day was awful ... she ceased to breathe that terrible breathing just before the [afternoon] whistle sounded for six." Dickinson's chief physician gave the cause of death as Bright's disease and its duration as two and a half years.

Dickinson was buried, laid in a white coffin with vanilla scented heliotrope, a Lady's Slipper orchid, and a "knot of blue field violets" placed about it. The funeral service, held in the Homestead's library, was simple and short; Higginson, who had only met her twice, read "No Coward Soul Is Mine", a poem by Emily Brontë that had been a favorite of Dickinson's. At Dickinson's request, her "coffin [was] not driven but carried through fields of buttercups" for burial in the family plot at West Cemetery on Triangle Street.

Despite Dickinson's prolific writing, fewer than a dozen of her poems were published during her lifetime. After her younger sister Lavinia discovered the collection of nearly eighteen hundred poems, Dickinson's first volume was published four years after her death. Until the 1955 publication of Dickinson's Complete Poems by Thomas H. Johnson, her poems were considerably edited and altered from their manuscript versions. Since 1890 Dickinson has remained continuously in print.

A few of Dickinson's poems appeared in Samuel Bowles' Springfield Republican between 1858 and 1868. They were published anonymously and heavily edited, with conventionalized punctuation and formal titles. The first poem, "Nobody knows this little rose", may have been published without Dickinson's permission. The Republican also published "A narrow Fellow in the Grass" as "The Snake"; "Safe in their Alabaster Chambers –" as "The Sleeping"; and "Blazing in the Gold and quenching in Purple" as "Sunset". The poem "I taste a liquor never brewed – " is an example of the edited versions; the last two lines in the first stanza were completely rewritten for the sake of conventional rhyme.

Original wording I taste a liquor never brewed – From Tankards scooped in Pearl – Not all the Frankfort Berries Yield such an Alcohol!

Republican version I taste a liquor never brewed – From Tankards scooped in Pearl – Not Frankfort Berries yield the sense Such a delirious whirl!

In 1864, several poems were altered and published in Drum Beat, to raise funds for medical care for Union soldiers in the war. Another appeared in April 1864 in the Brooklyn Daily Union.

In the 1870s, Higginson showed Dickinson's poems to Helen Hunt Jackson, who had coincidentally been at the Academy with Dickinson when they were girls. Jackson was deeply involved in the publishing world, and managed to convince Dickinson to publish her poem "Success is counted sweetest" anonymously in a volume called A Masque of Poets. The poem, however, was altered to agree with contemporary taste. It was the last poem published during Dickinson's lifetime.

After Dickinson's death, Lavinia Dickinson kept her promise and burned most of the poet's correspondence. Significantly though, Dickinson had left no instructions about the forty notebooks and loose sheets gathered in a locked chest. Lavinia recognized the poems' worth and became obsessed with seeing them published. She turned first to her brother's wife and then to Mabel Loomis Todd, her brother's mistress, for assistance. A feud ensued, with the manuscripts divided between the Todd and Dickinson houses, preventing complete publication of Dickinson's poetry for more than half a century.

The first volume of Dickinson's Poems, edited jointly by Mabel Loomis Todd and T.W. Higginson, appeared in November 1890. Although Todd claimed that only essential changes were made, the poems were extensively edited to match punctuation and capitalization to late 19th century standards, with occasional rewordings to reduce Dickinson's obliquity. The first 115 poem volume was a critical and financial success, going through eleven printings in two years. Poems: Second Series followed in 1891, running to five editions by 1893; a third series appeared in 1896. One reviewer, in 1892, wrote: "The world will not rest satisfied till every scrap of her writings, letters as well as literature, has been published". Two years later, two volumes of Dickinson's letters, heavily edited, appeared. In parallel, Susan Dickinson placed a few of Dickinson's poems in literary magazines such as Scribner's Magazine and The Independent.

Between 1914 and 1929, Dickinson's niece, Martha Dickinson Bianchi, published a new series of collections, including many previously unpublished poems, with similarly normalized punctuation and capitalization. Other volumes edited by Todd and Bianchi followed through the 1930s, gradually making more previously unpublished poems available.

The first scholarly publication came in 1955 with a complete new three volume set edited by Thomas H. Johnson. It formed the basis of all later Dickinson scholarship. For the first time, the poems were printed very nearly as Dickinson had left them in her manuscripts. They were untitled, only numbered in an approximate chronological sequence, strewn with dashes and irregularly capitalized, and often extremely elliptical in their language. Three years later, Johnson edited and published, along with Theodora Ward, a complete collection of Dickinson's letters.

In 1981, The Manuscript Books of Emily Dickinson was published. Using the physical evidence of the original papers, the poems were intended to be published in their original order for the first time. Editor Ralph W. Franklin relied on smudge marks, needle punctures and other clues to reassemble the poet's packets. Since then, many critics have argued for thematic unity in these small collections, believing the ordering of the poems to be more than chronological or convenient.

Dickinson biographer Alfred Habegger wrote in his 2001 work My Wars Are Laid Away in Books: The Life of Emily Dickinson that "The consequences of the poet's failure to disseminate her work in a faithful and orderly manner are still very much with us".

Dickinson's poems generally fall into three distinct periods, the works in each period having certain general characters in common.

• Pre - 1861. These are often conventional and sentimental in nature. Thomas H. Johnson, who later published The Poems of Emily Dickinson, was able to date only five of Dickinson's poems before 1858. Two of these are mock valentines done in an ornate and humorous style, and two others are conventional lyrics, one of which is about missing her brother Austin. The fifth poem, which begins "I have a Bird in spring", conveys her grief over the feared loss of friendship and was sent to her friend Sue Gilbert.
• 1861 – 1865. This was her most creative period — these poems are more vigorous and emotional. Johnson estimated that she composed 86 poems in 1861, 366 in 1862, 141 in 1863, and 174 in 1864. He also believed that this is when she fully developed her themes of life and death.
• Post - 1866. It is estimated that two - thirds of the entire body of her poetry was written before this year.

The extensive use of dashes and unconventional capitalization in Dickinson's manuscripts, and the idiosyncratic vocabulary and imagery, combine to create a body of work that is "far more various in its styles and forms than is commonly supposed". Dickinson avoids pentameter, opting more generally for trimeter, tetrameter and, less often, dimeter. Sometimes her use of these meters is regular, but oftentimes it is irregular. The regular form that she most often employs is the ballad stanza, a traditional form that is divided into quatrains, using tetrameter for the first and third lines and trimeter for the second and fourth, while rhyming the second and fourth lines (ABCB). Though Dickinson often uses perfect rhymes for lines two and four, she also makes frequent use of slant rhyme. In some of her poems, she varies the meter from the traditional ballad stanza by using trimeter for lines one, two and four, while only using tetrameter for line three.

Since many of her poems were written in traditional ballad stanzas with ABCB rhyme schemes, some of these poems can be sung to fit the melodies of popular folk songs and hymns that also use the common meter, employing alternating lines of iambic tetrameter and iambic trimeter. Familiar examples of such songs are "O Little Town of Bethlehem" and "Amazing Grace'".

Dickinson scholar and poet Anthony Hecht finds resonances in Dickinson's poetry not only with hymns and song forms but also with psalms and riddles, citing the following example: "Who is the East? / The Yellow Man / Who may be Purple if he can / That carries the Sun. / Who is the West? / The Purple Man / Who may be Yellow if He can / That lets Him out again."

Late 20th century scholars are "deeply interested" by Dickinson's highly individual use of punctuation and lineation (line lengths and line breaks). Following the publication of one of the few poems that appeared in her lifetime – "A narrow Fellow in the Grass", published as "The Snake" in the Republican – Dickinson complained that the edited punctuation (an added comma and a full stop substitution for the original dash) altered the meaning of the entire poem.

Original wording A narrow Fellow in the Grass Occasionally rides – You may have met Him – did you not His notice sudden is –

Republican version A narrow Fellow in the Grass Occasionally rides – You may have met Him – did you not, His notice sudden is.

As Farr points out, "snakes instantly notice you"; Dickinson's version captures the "breathless immediacy" of the encounter; and The Republican's punctuation renders "her lines more commonplace". With the increasingly close focus on Dickinson's structures and syntax has come a growing appreciation that they are "aesthetically based". Although Johnson's landmark 1955 edition of poems was relatively unaltered from the original, later scholars critiqued it for deviating from the style and layout of Dickinson's manuscripts. Meaningful distinctions, these scholars assert, can be drawn from varying lengths and angles of dash, and differing arrangements of text on the page. Several volumes have attempted to render Dickinson's handwritten dashes using many typographic symbols of varying length and angle. R. W. Franklin's 1998 variorum edition of the poems provided alternate wordings to those chosen by Johnson, in a more limited editorial intervention. Franklin also used typeset dashes of varying length to approximate the manuscripts' dashes more closely.

Dickinson left no formal statement of her aesthetic intentions and, because of the variety of her themes, her work does not fit conveniently into any one genre. She has been regarded, alongside Emerson (whose poems Dickinson admired), as a Transcendentalist. However, Farr disagrees with this analysis saying that Dickinson's "relentlessly measuring mind ... deflates the airy elevation of the Transcendental". Apart from the major themes discussed below, Dickinson's poetry frequently uses humor, puns, irony and satire.

• Flowers and gardens. Farr notes that Dickinson's "poems and letters almost wholly concern flowers" and that allusions to gardens often refer to an "imaginative realm ... wherein flowers [are] often emblems for actions and emotions". She associates some flowers, like gentians and anemones, with youth and humility; others with prudence and insight. Her poems were often sent to friends with accompanying letters and nosegays. Farr notes that one of Dickinson's earlier poems, written about 1859, appears to "conflate her poetry itself with the posies": "My nosegays are for Captives – / Dim – long expectant eyes – / Fingers denied the plucking, / Patient till Paradise – / To such, if they sh'd whisper / Of morning and the moor – / They bear no other errand, / And I, no other prayer".
• The Master poems. Dickinson left a large number of poems addressed to "Signor", "Sir" and "Master", who is characterized as Dickinson's "lover for all eternity". These confessional poems are often "searing in their self - inquiry" and "harrowing to the reader" and typically take their metaphors from texts and paintings of Dickinson's day. The Dickinson family themselves believed these poems were addressed to actual individuals but this view is frequently rejected by scholars. Farr, for example, contends that the Master is an unattainable composite figure, "human, with specific characteristics, but godlike" and speculates that Master may be a "kind of Christian muse".
• Morbidity. Dickinson's poems reflect her "early and lifelong fascination" with illness, dying and death. Perhaps surprisingly for a New England spinster, her poems allude to death by many methods: "crucifixion, drowning, hanging, suffocation, freezing, premature burial, shooting, stabbing and guillotinage". She reserved her sharpest insights into the "death blow aimed by God" and the "funeral in the brain", often reinforced by images of thirst and starvation. Dickinson scholar Vivian Pollak considers these references an autobiographical reflection of Dickinson's "thirsting - starving persona", an outward expression of her needy self image as small, thin and frail. Dickinson's most psychologically complex poems explore the theme that the loss of hunger for life causes the death of self and place this at "the interface of murder and suicide".
• Gospel poems. Throughout her life, Dickinson wrote poems reflecting a preoccupation with the teachings of Jesus Christ and, indeed, many are addressed to him. She stresses the Gospels' contemporary pertinence and recreates them, often with "wit and American colloquial language". Scholar Dorothy Oberhaus finds that the "salient feature uniting Christian poets ... is their reverential attention to the life of Jesus Christ" and contends that Dickinson's deep structures place her in the "poetic tradition of Christian devotion" alongside Hopkins, Eliot and Auden. In a Nativity poem, Dickinson combines lightness and wit to revisit an ancient theme: "The Savior must have been / A docile Gentleman – / To come so far so cold a Day / For little Fellowmen / The Road to Bethlehem / Since He and I were Boys / Was leveled, but for that twould be / A rugged billion Miles –".
• The Undiscovered Continent. Academic Suzanne Juhasz considers that Dickinson saw the mind and spirit as tangible visitable places and that for much of her life she lived within them. Often, this intensely private place is referred to as the "undiscovered continent" and the "landscape of the spirit" and embellished with nature imagery. At other times, the imagery is darker and forbidding — castles or prisons, complete with corridors and rooms — to create a dwelling place of "oneself" where one resides with one's other selves. An example that brings together many of these ideas is: "Me from Myself – to banish – / Had I Art – / Impregnable my Fortress / Unto All Heart – / But since myself— assault Me – / How have I peace / Except by subjugating / Consciousness. / And since We're mutual Monarch / How this be / Except by Abdication – / Me – of Me?".

The surge of posthumous publication gave Dickinson's poetry its first public exposure. Backed by Higginson and with a favorable notice from William Dean Howells, an editor of Harper's Magazine, the poetry received mixed reviews after it was first published in 1890. Higginson himself stated in his preface to the first edition of Dickinson's published work that the poetry's quality "is that of extraordinary grasp and insight", albeit "without the proper control and chastening" that the experience of publishing during her lifetime might have conferred. His judgment that her opus was “incomplete and unsatisfactory” would be echoed in the essays of the New Critics in the 1930s.

Maurice Thompson, who was literary editor of The Independent for twelve years, noted in 1891 that her poetry had "a strange mixture of rare individuality and originality". Some critics hailed Dickinson's effort, but disapproved of her unusual non-traditional style. Andrew Lang, a British writer, dismissed Dickinson's work, stating that "if poetry is to exist at all, it really must have form and grammar, and must rhyme when it professes to rhyme. The wisdom of the ages and the nature of man insist on so much". Thomas Bailey Aldrich, a poet and novelist, equally dismissed Dickinson's poetic technique in The Atlantic Monthly in January 1892: "It is plain that Miss Dickinson possessed an extremely unconventional and grotesque fancy. She was deeply tinged by the mysticism of Blake, and strongly influenced by the mannerism of Emerson ... But the incoherence and formlessness of her — versicles are fatal ... an eccentric, dreamy, half educated recluse in an out - of - the - way New England village (or anywhere else) cannot with impunity set at defiance the laws of gravitation and grammar".

Critical attention to Dickinson's poetry was meager from 1897 to the early 1920s. By the start of the 20th century, interest in her poetry became broader in scope and some critics began to consider Dickinson as essentially modern. Rather than seeing Dickinson's poetic styling as a result of lack of knowledge or skill, modern critics believed the irregularities were consciously artistic. In a 1915 essay, Elizabeth Shepley Sergeant called the poet's inspiration "daring" and named her "one of the rarest flowers the sterner New England land ever bore". With the growing popularity of modernist poetry in the 1920s, Dickinson's failure to conform to 19th century poetic form was no longer surprising nor distasteful to new generations of readers. Dickinson was suddenly referred to by various critics as a great woman poet, and a cult following began to form.

In the 1930s, a number of the New Critics – among them R.P. Blackmur, Allen Tate, Cleanth Brooks and Yvor Winters – appraised the significance of Dickinson's poetry. As critic Roland Hagenbüchle pointed out, their "affirmative and prohibitive tenets turned out to be of special relevance to Dickinson scholarship". Blackmur, in an attempt to focus and clarify the major claims for and against the poet's greatness, wrote in a landmark 1937 critical essay: "... she was a private poet who wrote as indefatigably as some women cook or knit. Her gift for words and the cultural predicament of her time drove her to poetry instead of antimacassars ... She came... at the right time for one kind of poetry: the poetry of sophisticated, eccentric vision."

The second wave of feminism created greater cultural sympathy for her as a female poet. In the first collection of critical essays on Dickinson from a feminist perspective, she is heralded as the greatest woman poet in the English language. Biographers and theorists of the past tended to separate Dickinson's roles as a woman and a poet. For example, George Whicher wrote in his 1952 book This Was a Poet: A Critical Biography of Emily Dickinson, "Perhaps as a poet [Dickinson] could find the fulfillment she had missed as a woman." Feminist criticism, on the other hand, declares that there is a necessary and powerful conjunction between Dickinson being a woman and a poet. Adrienne Rich theorized in Vesuvius at Home: The Power of Emily Dickinson (1976) that Dickinson's identity as a woman poet brought her power: "[she] chose her seclusion, knowing she was exceptional and knowing what she needed... She carefully selected her society and controlled the disposal of her time... neither eccentric nor quaint; she was determined to survive, to use her powers, to practice necessary economics."

Some scholars question the poet's sexuality, theorizing that the numerous letters and poems that were dedicated to Susan Gilbert Dickinson indicate a lesbian romance, and speculating about how this may have influenced her poetry. Critics such as John Cody, Lillian Faderman, Vivian R. Pollak, Paula Bennett, Judith Farr, Ellen Louise Hart, and Martha Nell Smith have argued that Susan was the central erotic relationship in Dickinson's life.

Emily Dickinson is now considered a powerful and persistent figure in American culture. Although much of the early reception concentrated on Dickinson's eccentric and secluded nature, she has become widely acknowledged as an innovative, pre-modernist poet. As early as 1891, William Dean Howells wrote that "If nothing else had come out of our life but this strange poetry, we should feel that in the work of Emily Dickinson, America, or New England rather, had made a distinctive addition to the literature of the world, and could not be left out of any record of it." Twentieth century critic Harold Bloom has placed her alongside Walt Whitman, Wallace Stevens, Robert Frost, T.S. Eliot, and Hart Crane as a major American poet.

Dickinson is taught in American literature and poetry classes in the United States from middle school to college. Her poetry is frequently anthologized and has been used as texts for art songs by composers such as Aaron Copland, Nick Peros, John Adams and Michael Tilson Thomas. Several schools have been established in her name; for example, two Emily Dickinson Elementary Schools exist in Bozeman, Montana, and Redmond, Washington. A few literary journals — including The Emily Dickinson Journal, the official publication of the Emily Dickinson International Society — have been founded to examine her work. An 8-cent commemorative stamp in honor of Dickinson was issued by the United States Postal Service on August 28, 1971 as the second stamp in the "American Poet" series. A one woman play entitled The Belle of Amherst first appeared on Broadway in 1976, winning several awards; it was later adapted for television.

Dickinson's herbarium, which is now held in the Houghton Library at Harvard University, was published in 2006 as Emily Dickinson's Herbarium by Harvard University Press. The original work was complied by Dickinson during her years at Amherst Academy, and consists of 424 pressed specimens of plants arranged on 66 pages of a bound album. A digital facsimile of the herbarium is available online. The Amherst Jones Library's Special Collections department has an Emily Dickinson Collection consisting of approximately seven thousand items, including original manuscript poems and letters, family correspondence, scholarly articles and books, newspaper clippings, theses, plays, photographs and contemporary artwork and prints. The Archives and Special Collections at Amherst College has substantial holdings of Dickinson's manuscripts and letters as well as a lock of Dickinson's hair and the original of the only positively identified image of the poet. In 1965, in recognition of Dickinson's growing stature as a poet, the Homestead was purchased by Amherst College. It opened to the public for tours, and also served as a faculty residence for many years. The Emily Dickinson Museum was created in 2003 when ownership of the Evergreens, which had been occupied by Dickinson family heirs until 1988, was transferred to the college.
