Like the protagonists of Renaissance epics, such as Milton's Satan and Faustus, Frankenstein emerges as a heroic figure in his quest to challenge divine powers. Drawing from the literary tradition of Greco-Roman heroic epics, Mary Shelley, as a writer, accentuates two key aspects of companionship in her Frankenstein: the nature of homosexuality shared between Frankenstein and his male companion, Clerval, and the cherished values of family and domesticity embodied by Elizabeth, Frankenstein's female companion. By employing a dialectical approach, Shelley skillfully explores the significance of male and female roles as complementary companions during the hero's journey. This examination focuses primarily on the roles of Clerval and Elizabeth as they accompany Frankenstein in his heroic scientific exploration. The portrayal of both the nature of homosexuality that Clerval and Frankenstein seem to hold and Elizabeth's love with Frankenstein serves to emphasize the importance of companionship and how it plays a vital role in the hero's scientific journey. Therefore, this study sheds light on the exploration of companionship in Frankenstein, offering insights into how these relationships contribute to the hero's quest and the broader themes of the novel.
