There is only this animal mentioned in the Bible, the name of which
begins with U, and of this I cannot give you a picture, because no
person now knows what sort of an animal it was. Some suppose it was a
kind of wild goat; others think that it was a sort of deer; and others,
that it was what we call the rhinoceros. Perhaps you have seen pictures
with the name of the unicorn under them; but you must remember that
those who made them only guessed it was so, and that no person can
certainly tell what it was.
