Don Quixote

"In short, his wits being quite gone, he hit upon the strangest notion that every madman in this world hit upon, and that was that he fancied it was right and requisite, as well for the support of his own honour as for the service of his country, that he should make a knight-errant of himself, roaming the world over in full armour and on horseback in quest of adventures, and putting in practice himself all that he had read of as being the usual practices of knights-errant; righting every kind of wrong, and exposing himself to peril and danger from which, in the issue, he was to reap eternal renown and fame. Already the poor man saw himself crowned by the might of his arm Emperor of Trebizond at least; and so, led away by the intense enjoyment he found in these pleasant fancies, he set himself forthwith to put his scheme into execution."-- Excerpt It's the classic adventure of the "renowned Don Quixote de la Mancha." He attacks windmills, believes a peasant girl to be a lady, and fancies that he is a knight-errant, dedicated to righting wrongs and rescuing damsels in distress.
