<P> Before a fit of madness turned Alonso Quijano into Don Quixote, Sancho Panza was indeed his servant . When the novel begins, Sancho has been married for a long time to a woman named Teresa Cascajo and has a daughter, María Sancha (also named Marisancha, Marica, María, Sancha, and Sanchica), who is said to be old enough to be married . Sancho's wife is described more or less as a feminine version of Sancho, both in looks and behaviour . When Don Quixote proposes Sancho to be his squire, neither he nor his family strongly oppose it . </P> <P> Sancho is illiterate and proud of it but by influence of his new master, he develops considerable knowledge about some books . Sancho instead provides the earthly wisdom of Spanish proverbs, surprising his master . During the travels with Don Quixote, he keeps contact with his wife by dictating letters addressed to her . </P> <P> 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 . Salvador de Madariaga detected that, as the book progresses, there is a "Quixotization" of Sancho and a "Sanchification" of Don Quixote, so much that, when the knight recovers sanity on his deathbed, it is Sancho who tries to convince him to become pastoral shepherds . </P> <P> In the novel, Don Quixote comments on the historical state and condition of Aragón and Castilla, which are vying for power in Europe . Sancho Panza represents, among other things, the quintessentially Spanish brand of skepticism of the period . </P>
