"Sancho Panza"

Sancho Panza is the peasant sidekick of Don Quixote in the 17th century novel of that name.  His role in the novel is to puncture the elevated, chivalric bombast of his companion with earthier concerns and crude humour.  While less educated than Quixote, Panza frequently displays a canniness and common sense his social superior lacks.  Despite disagreements, he is loyal to Quixote, although this is perhaps motivated by Quixote's promise to make Panza the governor of an island in return for his assistance.
