“If Gothic literature had a family tree, its twisted gnarled branches chock-full of imperiled, swooning heroines and mysterious monks, with ghosts who sit light on the branches, and Frankenstein’s monster who sits heavy, with troops of dwarves, and winking nuns, and stunted, mostly nonflammable babies, at its base would sit Horace Walpole’s The Castle of Otranto.” Carrie Frye writes for Longreads about the history and personality behind the first Gothic novel, which turns 250 this year.
