 The opera has typical elements of the Romantic in its Gothic mode, including an exotic Scottish locale, a lost heir, a mysterious castle, a hidden fortune, and a ghost, in this case benevolent.The work was one of the first attempts to introduce the fantastic into opera and is a model for works such as Giacomo Meyerbeer's "Robert le diable" (1831) and Charles Gounod's "Faust" (1859).The opera's musical style also heavily influenced later operas like "Lucia di Lammermoor", "I puritani" and "La jolie fille de Perth".
