In fiction, the adventurer figure or Picaro may be regarded as a descendant of the knight-errant of Medieval romance. Like the knight, the adventurer roams through episodic encounters, usually involving wealth, romance, or fighting. Unlike the knight, the adventurer was a realistic figure, often lower class or otherwise impoverished, who is forced to make his way to fortune, often by deceit. Also, an adventurer is a roguish hero of low social class who lives by his or her wits in a corrupt society.
