“Two of them,” said Sancho, “are green, two bloodred, two blue, and one a mixture of all colours.”

“An odd sort of goat, that,” said the duke; “in this earthly region of ours we have no such colours; I mean goats of such colours.”

“That’s very plain,” said Sancho; “of course there must be a difference between the goats of heaven and the goats of the earth.”

“Tell me, Sancho,” said the duke, “did you see any he-goat among those goats?”

“No, señor,” said Sancho; “but I have heard say that none ever passed the horns of the moon.”
