In its anonymous review of Christina Rossetti's Speaking Likenesses (1874), the Academy notes rather hopelessly: “this will probably be one of the most popular children's books this winter. We wish we could understand it” (606). The reviewer – who later dwells on the “uncomfortable feeling” generated by this children's tale and its accompanying images – still counts as the most generous among the largely puzzled and horrified readership of Rossetti's story about three sets of girls experiencing violence and failure in their respective fantasy worlds (606). While clearly such dystopic plots are not out of place in Victorian literature about children, something about Rossetti's unusual narrative bothered her contemporaries. John Ruskin, for instance, bluntly wondered how Rossetti and Arthur Hughes, who illustrated the story, together could “sink so low” (qtd. in Auerbach and Knoepflmacher 318). In any case, the book still sold on the Christmas market, and a few months later, Rossetti would publish Annus Domini, a benign pocketbook of daily prayers that stands in stark contrast to the grim prose of Speaking Likenesses. It is therefore tempting to cast this work of children's fiction as a strange anomaly in Rossetti's oeuvre, which from the 1870s, beginning with Annus Domini, to her death in 1894, became almost exclusively dominated by devotional prose and poetry. In contrast, I argue in the following essay that Speaking Likenesses points to a widespread interest throughout Rossetti's writing – but especially in her most well-known poems from Goblin Market and Other Poems (1862) and A Prince's Progress (1866) – in alternative modes of sociality that refract a conceptual preoccupation with likeness, rather than difference. Following traditions of critical thought that have paid increasing attention to relations that resist oppositional logic – Stephanie Engelstein and Eve Kosovsky Sedgwick's late work comes to mind here – I establish the primacy of a horizontal axis of similarity in both Speaking Likenesses and Rossetti's most canonical poem, “Goblin Market.” For Rossetti, the lure of similarity, or minimal difference, manifests itself most often in siblinghood and more specifically, sisterhood, the dominant kinship relation throughout her lyrics from Goblin Market and Other Poems. Sisterhood anchors the title poem I will examine in this essay, as well as shorter verses such as “Noble Sisters” and “Sister Maude.” At issue in such relations of likeness is the discreteness of a (typically) feminine self. For Rossetti, shunning oppositional structures of desire and difference that typically produce individuation (exemplified in the heterosexual couple form and the titles of her uneasy lyrics “He and She” and “Wife to Husband”) allows for a new (albeit perilous) space to carve out one's particularity as a gendered being.
