Jane Morris significantly influenced literature and art, particularly through her association with Dante Gabriel Rossetti. As Rossetti's muse and erotic partner, she became the dominant figure in many of his paintings, often impersonating roles of prominent women from medieval literature or ancient mythology 1.
Her enigmatic and melancholic figure contributed to the formation of the 19th-century Victorian England middle-class female stereotype and the second phase of Pre-Raphaelite art womanhood 1.
Additionally, Jane's involvement in many of her husband William Morris's endeavors, such as the family firm Morris & Co., the Society for the Protection of Ancient Buildings, the 1882 Icelandic Relief Committee, and the Kelmscott Press, further demonstrates her influence on art and literature 2.
Even more specifically, she served as the model for the heroine in Vernon Lee's novel "Miss Brown". Less verifiable but just as specific, Jane may well have inspired George Bernard Shaw's character Eliza Doolittle in "Pygmalion", which later went on to become adapted into the feature film, "My Fair Lady".
