Lothario

Lothario is a male first name which came to connote an unscrupulous seducer of women in The Impertinent Curiosity, a metastory in Don Quixote.

The Novel of The Man Who Was Recklessly Curious

Don Quixote, Part One contains stories that do not directly involve the two main characters, but which are narrated by some of the picaresque figures encountered by Quixote and Sancho during their travels. The longest and best known story is El Curioso Impertinente (The Impertinently Curious Man), in Part One, Book Four, chapters 33–35, which is read to a group of travellers at an inn, about a Florentine nobleman, Anselmo, who becomes obsessed with testing his wife's fidelity, and talks his close friend Lothario into attempting to seduce her. In Part Two, the author acknowledges the criticism of his digressions in Part One and promises to concentrate the narrative on the central characters (although at one point he laments that his narrative muse has been constrained in this manner).
