Sancho Panza
Sancho Panza offers interpolated narrative voice throughout the tale, a literary convention invented by Cervantes. Sancho Panza is precursor to "the sidekick," and is symbolic of practicality over idealism. Sancho is the everyman, who, though not sharing his master's delusional "enchantment" until late in the novel, remains his ever-faithful companion realist, and functions as the clever sidekick.
