When the nephew heard this, he exclaimed, “Uncle, for God’s sake! if what you say be true, the devil has brought me to this country; for certainly, if these are cows, then I have lost my senses, for in all parts of the world these are mares and not cows.” But Don Alvar persisted that he was right in saying they were cows and not mares. And thus they argued until Vascuñana came up to them, when they related to her all that had passed between them.
Now, although she thought her nephew right, yet, for the same reason as before, she said so much in support of her husband, and that, too, with such apparent truth and inward conviction, that the nephew and those with the mares began to think that their sight and judgment erred and that what Don Alvar had said was true; and so the debate ended.
Again Don Alvar and his nephew proceeded on their road homeward, and had proceeded at a considerable distance when they arrived at a river, on the banks of which were a number of mills. While their horses were drinking, Don Alvar remarked that river ran in the direction from which it flowed, and that the mills received their water from a contrary point. When the nephew heard this he thought to a certainty he himself had lost his senses, for, as he appeared to be wrong with respect to the mares and cows, so might he be in error here also, and the river might really run toward and not from its source. Nevertheless, he contended the point. When Vascuñana, on her arrival, found them again warmly disputing, she begged to know the cause. They then informed her; when, although, as before, it appeared to her that the nephew was right, yet she could not be persuaded that her husband was wrong, and so again supported his opinion; and this time with so many good arguments, that the nephew and those present felt that they must have been in error. And it remains a proverb to this day that, “If the husband affirms that the river runs up to its source, the good wife ought to believe it and say that it is true.”
Now, when the nephew heard all this, supposing that Don Alvar Fañez must be right, he began to feel very unhappy and to suspect that he was losing his senses, etc., etc.

Pet. Come on, o’ God’s name; once more toward our father’s.
Good Lord, how bright and goodly shines the moon!
Kath. The moon! the sun; it is not moonlight now.
Pet. I say it is the moon that shines so bright.
