"The Lady of the Lake is a narrative poem by Sir Walter Scott, first published in 1810. ...Its influence is indirect: Schubert's Ellens Dritter Gesang (later adapted to use the full lyrics of the Latin Ave Maria), Rossini's La Donna del Lago (1819), the Ku Klux Klan custom of cross burning, the last name of the U.S. abolitionist Frederick Douglass, and the song "Hail to the Chief", were all inspired by the poem."
