“And I’M Going To Destroy You.”: Persona And Gender Performativity In Ernest Hemingway’S The Garden Of Eden, Nicole Minton

UNLV Theses, Dissertations, Professional Papers, and Capstones

While debate of Ernest Hemingway’s authorial masculine persona in connection to The Garden of Eden has been a point of interest in literary scholarship, no single work has tied together theory of gender performativity to persona. A borderline parodic display of masculine adventure has encouraged a one-dimensional view of Hemingway, who is viewed by audiences as the pinnacle of masculinity. However, this image is complicated by the publication of Eden, which reveals an author interested in gender and sexual identity fluidity. Rarely has a single text called into question so controversially an author’s public image. Eden showcases an empathetic …
