In short, he repeated all that Pedro had related to Don Quixote.
This conversation dropped, and another was commenced by him who was called Vivaldo asking Don Quixote what was the reason that led him to go armed in that fashion in a country so peaceful.

To which Don Quixote replied, "The pursuit of my calling does not allow or permit me to go in any other fashion; easy life, enjoyment, and repose were invented for soft courtiers, but toil, unrest, and arms were invented and made for those alone whom the world calls knights-errant, of whom I, though unworthy, am the least of all." The instant they heard this all set him down as mad, and the better to settle the point and discover what kind of madness his was, Vivaldo proceeded to ask him what knights-errant meant.
"Have not your worships," replied Don Quixote, "read the annals and histories of England, in which are recorded the famous deeds of King Arthur, whom we in our popular Castilian invariably call King Artus, with regard to whom it is an ancient tradition, and commonly received all over that kingdom of Great Britain, that this king did not die, but was changed by magic art into a raven, and that in process of time he is to return to reign and recover his kingdom and sceptre; for which reason it cannot be proved that from that time to this any Englishman ever killed a raven?
Well, then, in the time of this good king that famous order of chivalry of the Knights of the Round Table was instituted, and the amour of Don Lancelot of the Lake with the Queen Guinevere occurred, precisely as is there related, the go-between and confidante therein being the highly honourable dame Quintanona, whence came that ballad so well known and widely spread in our Spain-- O never surely was there knight So served by hand of dame, As served was he Sir Lancelot hight When he from Britain came-- with all the sweet and delectable course of his achievements in love and war.

Handed down from that time, then, this order of chivalry went on extending and spreading itself over many and various parts of the world; and in it, famous and renowned for their deeds, were the mighty Amadis of Gaul with all his sons and descendants to the fifth generation, and the valiant Felixmarte of Hircania, and the never sufficiently praised Tirante el Blanco, and in our own days almost we have seen and heard and talked with the invincible knight Don Belianis of Greece.

This, then, sirs, is to be a knight-errant, and what I have spoken of is the order of his chivalry, of which, as I have already said, I, though a sinner, have made profession, and what the aforesaid knights professed that same do I profess, and so I go through these solitudes and wilds seeking adventures, resolved in soul to oppose my arm and person to the most perilous that fortune may offer me in aid of the weak and needy." By these words of his the travellers were able to satisfy themselves of Don Quixote's being out of his senses and of the form of madness that overmastered him, at which they felt the same astonishment that all felt on first becoming acquainted with it; and Vivaldo, who was a person of great shrewdness and of a lively temperament, in order to beguile the short journey which they said was required to reach the mountain, the scene of the burial, sought to give him an opportunity of going on with his absurdities.

So he said to him, "It seems to me, Senor Knight-errant, that your worship has made choice of one of the most austere professions in the world, and I imagine even that of the Carthusian monks is not so austere." "As austere it may perhaps be," replied our Don Quixote, "but so necessary for the world I am very much inclined to doubt.
