Controversy about the painting has centered on its violence, and on the melodramatic presence of the woman. Modern scholars have suggested that the painting may be read in terms of castration anxiety and fantasies of mastery over the body (e.g. Michael Fried), and that it documents Eakins's ambivalence about representing sex difference (e.g. Jennifer Doyle). The painting has also been understood to be drawing an analogy between painting and surgery and as identifying the work of the artist with the emergence of surgery as a respected profession.
