this one of
the cave, I see no way of accepting it as true, as it passes all
reasonable bounds. For me to believe that Don Quixote could lie, he being
the most truthful gentleman and the noblest knight of his time, is
impossible; he would not have told a lie though he were shot to death
with arrows. On the other hand, I reflect that he related and told the
story with all the circumstances detailed, and that he could not in so
short a space have fabricated such a vast complication of absurdities;
if, then, this adventure seems apocryphal, it is no fault of mine; and
so, without affirming its falsehood or its truth, I write it down. Decide
for thyself in thy wisdom, reader; for I am not bound, nor is it in my
power, to do more; though certain it is they say that at the time of his
death he retracted, and said he had invented it, thinking it matched and
tallied with the adventures he had read of in his histories." And then he
goes on to say:

The cousin was amazed as well at Sancho's boldness as at the patience of
his master, and concluded that the good temper the latter displayed arose
from the happiness he felt at having seen his lady Dulcinea, even
enchanted as she was; because otherwise the words and language Sancho had
addressed to him deserved a thrashing; for indeed he seemed to him to
have been rather impudent to his master, to whom he now observed, "I,
Senor Don Quixote of La Mancha, look upon the time I have spent in
travelling with your worship as very well employed, for I have gained
four things in the course of it; the first is that I have made your
acquaintance, which I consider great good fortune; the second, that I
have learned what the cave of Montesinos contains, together with the
transformations of Guadiana and of the lakes of Ruidera; which will be of
use to me for the Spanish Ovid that I have in hand; the third, to have
discovered the antiquity of cards, that they were in use at least in the
time of Charlemagne, as may be inferred from the words you say Durandarte
uttered when, at the end of that long spell while Montesinos was talking
to him, he woke up and said, 'Patience and shuffle.' This phrase and
expression he could not have learned while he was enchanted, but only
before he had become so, in France, and in the time of the aforesaid
emperor Charlemagne. And this demonstration is just the thing for me for
that other book I am writing, the 'Supplement to Polydore Vergil on the
Invention of Antiqui
