This study examines the figures of Ophelia and the Arthurian Vivien in the poetry of the fin-de-siècle lesbian poet, Pauline Tarn, who wrote in French under the name Renée Vivien (1877-1909). Often depicted in Victorian literature and art, the mad self-sacrificing Ophelia, and the seductive sorceress Vivien of the Lake, represent two sides of a feminine gender dynamic that was shifting during the late nineteenth century. Vivien's problematic identification with these "Ladies of the Lake" highlights the conflicts and contradictions inherent in Sapphic decadence, and reveals both the restrictions suffered by creative women, and the disruptive possibilities of feminist poetic revisions.
