Marina Tsvetaeva and Sophia Parnok were both Russian poets living during the first half of the twentieth century. Tsvetaeva is considered one of the most prominent poets of the Silver Age, and is recognized for her innovative and complex style. Parnok is far less well-known, by Russians and scholars alike, and the process of re-establishing her as a figure in Russian literary history began just thirty years ago, with the work of scholars that will be discussed below. What connects these two women is the affair they conducted from 1914 to 1916, and the poetry they wrote chronicling it. This paper endeavors to examine the poetry of Tsvetaeva and Parnok in the context of that relationship, and also to consider how their poetry and thought on queerness evolved afterwards.
