The falsehood would then lie at my door, and as I am not a gentleman, I may be allowed to lie.” “Be of good heart, Planchet, you shall preserve your reputation as a veracious man.

Alexandre Dumas

The Three Musketeers

And so, after having composed, struck out, rejected, added to, unmade, and remade a multitude of names out of his memory and fancy, he decided upon calling him Rocinante, a name, to his thinking, lofty, sonorous, and significant of his condition as a hack before he became what he now was, the first and foremost of all the hacks in the world.42 Having got a name for his horse so much to his taste, he was anxious to get one for himself, and he was eight days more pondering over this point, till at last he made up his mind to call himself “Don Quixote,”43 whence, as has been already said, the authors of this veracious history have inferred that his name must have been beyond a doubt Quixada, and not Quesada as others would have it.
