In the 1840s, her family faced severe financial difficulties due to the deterioration of her father’s physical and mental health. In 1843, he was diagnosed with persistent bronchitis, possibly tuberculosis, and faced losing his sight. He gave up his teaching post at King’s College and though he lived another 11 years, he suffered from depression and was never physically well again. Rossetti’s mother began teaching to keep the family out of poverty and Maria became a live-in governess, a prospect that Christina Rossetti dreaded. At this time her brother William was working for the Excise Office and Gabriel was at art school, leaving Christina’s life at home to become one of increasing isolation. When she was 14, Rossetti suffered a nervous breakdown and left school. Bouts of depression and related illness followed. During this period she, her mother and her sister became absorbed in the Anglo-Catholic movement that developed in the Church of England. Religious devotion came to play a major role in Rossetti’s life.

Rossetti began writing down and dating her poems from 1842, most of which imitated her favoured poets. In 1847 she began experimenting with verse forms such as sonnets, hymns and ballads, while drawing narratives from the Bible, folk tales and the lives of saints. Her early pieces often feature meditations on death and loss, in the Romantic tradition. She published her first two poems (“Death’s Chill Between”, “Heart’s Chill Between”) in the Athenaeum in 1848, when she was 18. Under the pseudonym “Ellen Alleyne” she contributed to the literary magazine, The Germ, published by the Pre-Raphaelites from January to April 1850 and edited by her brother William. This marked the beginning of her public career.

Rossetti sat for several of Dante Gabriel Rossetti’s most famous paintings. In 1848, she was the model for the Virgin Mary in his first completed oil painting, The Girlhood of Mary Virgin, and the first work to be inscribed with the initials “PRB”, later revealed to signify the Pre-Raphaelite Brotherhood. The following year she modelled for his depiction of the Annunciation, Ecce Ancilla Domini. A line from her poem “Who shall deliver me?” inspired the famous painting by Fernand Khnopff called I lock my door upon myself. In 1849 she became seriously ill again, suffering from depression and sometime around 1857 had a major religious crisis.

In her late teens, Rossetti became engaged to the painter James Collinson, the first of three suitors. He was, like her brothers Dante and William, one of the founding members of the avant-garde artistic group, the Pre-Raphaelite Brotherhood (founded 1848). The engagement was broken in 1850 when he reverted to Catholicism. In 1853, when the Rossetti family was in continuing financial difficulties, Christina helped her mother keep a school in Fromefield, Frome, but it was not a success. (A plaque commemorates the house.) In 1854 the pair returned to London, where Christina’s father died. Later she became involved with the linguist Charles Cayley, but declined to marry him, also for religious reasons. The third offer came from the painter John Brett, whom she likewise refused.

Rossetti’s more critical reflections on the artistic movement begun by her brother find expression in her 1856 poem “In the Artist’s Studio”. Here she reflects on seeing multiple paintings of the same model. For Rossetti, the artist’s idealised vision of the model’s character begins to overwhelm his work, until “every canvas means/the one same meaning.” Dinah Roe, in her introduction to the Penguin Classics collection of Pre-Raphaelite poetry, argues that this critique of her brother and similar male artists is not so much about “the objectification of women” as about “the male artist’s self-worship”.

Rossetti’s most famous collection, Goblin Market and Other Poems, appeared in 1862, when she was 31. It received widespread critical praise, establishing her as the foremost female poet of the time. Hopkins, Swinburne and Tennyson lauded her, and with the death of Elizabeth Barrett Browning in 1861 she was hailed as her natural successor. The title poem is one of Rossetti’s best known. Although it is ostensibly about two sisters’ misadventures with goblins, critics have interpreted the piece in a variety of ways, seeing it as an allegory about temptation and salvation, a commentary on Victorian gender roles and female agency, and a work about erotic desire and social redemption. Rossetti was a volunteer worker from 1859 to 1870 at the St Mary Magdalene house of charity in Highgate, a refuge for former prostitutes, and it is suggested that Goblin Market may have been inspired by the “fallen women” she came to know. There are parallels with Coleridge’s The Rime of the Ancient Mariner in both poems’ religious themes of temptation, sin and redemption by vicarious suffering. Swinburne in 1883 dedicated A Century of Roundels to Rossetti, as she adopted his roundel form in a number of poems, for instance in Wife to Husband. She was ambivalent about women’s suffrage, but many scholars have found feminist themes in her poetry. She opposed slavery (in the American South), cruelty to animals (in the prevalent practice of animal experimentation), and the exploitation of girls in under-age prostitution.

In the later decades of her life, Rossetti suffered from Graves’ disease, diagnosed in 1872, suffering a near-fatal attack in the early 1870s. In 1893, she developed breast cancer and though the tumour was removed, there was a recurrence in September 1894. She died in Bloomsbury on 29 December 1894 and was buried in Highgate Cemetery. The place where she died, in Torrington Square, is marked with a stone tablet.

Rossetti maintained a large circle of friends and correspondents, and continued to write and publish for the rest of her life, focusing mainly on devotional writing and children’s poetry. In 1892, she wrote The Face of the Deep, a book of devotional prose, and oversaw production of a new and enlarged edition of Sing-Song in 1893.

Rossetti’s Christmas poem “In the Bleak Midwinter” became widely known in the English-speaking world after her death, when it was set as a Christmas carol, first by Gustav Holst and later by Harold Darke. Her poem “Love Came Down at Christmas” (1885) has also been widely arranged as a carol. Rossetti is honoured with a feast day on the liturgical calendar of the Anglican Church on 27 April. Up-Hill is an allegorical poem.She compares humanlife with a painful journey. In 1918, John Ireland set eight of her poems from Sing-Song: A Nursery Rhyme Book to music in his song cycle Mother and Child. The title of J. K. Rowling’s novel The Cuckoo’s Calling is based on a line in Rossetti’s poem A Dirge. The poem “Song” was an inspiration for Bear McCreary to write his musical composition When I Am Dead, published in 2015. Two of Rossetti’s poems, “Where Sunless Rivers Weep” and “Weeping Willow” were set to music by Barbara Arens in her All Beautiful & Splendid Things: 12 + 1 Piano Songs on Poems by Women (2017, Editions Musica Ferrum).

In 2000, as one of the many Millennium projects across the country, a poetry stone was placed in what used to be the grounds of North Hill House in Frome. On one side is an excerpt from her poem, “What Good Shall My Life Do Me”: “Love lights the sun: love through the dark/Lights the moon’s evanescent arc:/Same Love lights up the glow-worms spark.” She wrote of her brief stay in Frome, which had “an abundance of green slopes and gentle declivities: no boldness or grandeur but plenty of peaceful beauty.”

In 2011, Rossetti was the subject of Radio 4’s programme In Our Time.
