A compelling biography of the Renaissance painter, known equally for his magnetic personality and unusual subject matter: witchcraft and the sublime.     Painter, poet, and actor Salvator Rosa was one of the most engaging and charismatic personalities of seventeenth-century Italy. Although a gifted landscape painter, he longed to be seen as the preeminent philosopher-painter of his age. This new biography traces Rosa’s strategies of self-promotion and his creation of a new kind of audience for his art. The book describes the startling novelty of his subject matter—witchcraft and divination, as well as prophecies, natural magic, and dark violence—and his early exploration of a nascent aesthetic of the sublime.  Salvator Rosa shows how the artist, in a series of remarkable works, responded to new movements in thought and feeling, creating images that spoke to the deepest concerns of his age.
