Zastrozzi: A Romance is a Gothic novel by Percy Bysshe Shelley first published in 1810 in London by George Wilkie and John Robinson anonymously, with only the initials of the author's name, as "by P B S.". The first of Shelley's two early Gothic novellas, the other being St. Irvyne, outlines his atheistic worldview through the villain Zastrozzi[1] and touches upon his earliest thoughts on irresponsible self-indulgence and violent revenge. An 1810 reviewer wrote that the main character "Zastrozzi is one of the most savage and improbable demons that ever issued from a diseased brain".
