Perils of the night [electronic resource] : a feminist study of nineteenth-century Gothic by Mary Shelley’s Frankenstein; or, The Modern Prometheus deals with the monstrous in and around us, revealing the dark aspect beneath creation’s mystery and our quest for knowledge. Shelley gave us the first modern monster and a story that inspired (and still inspires) myriad tales across genres. We will examine the Romantic, Gothic, and scientific contexts in which she wrote and look back at the myths and stories that influenced her, the Promethean myth, the book of Genesis, and John Milton’s epicParadise Lost. That vantage will shed light on present-day retellings and narratives of mad scientists, monsters, and superheroes that-whether in literature, comic books, or film-extend the Frankenstein story.
