Fourthly, What Horns soever they be which pass amongst us, they are not surely the Horns of any one kind of Animal, but must proceed from several sorts of _Unicorns_. For some are wreathed, some not: That famous one which is preserved at St. _Dennis_ near _Paris_, hath wreathy spires, and chocleary turnings about it, which agreeth with the description of the _Unicorns_ Horn in _Ælian_. Those two in the treasure of St. _Mark_ are plain, and best accord with those of the _Indian_ Ass, or the descriptions of other _Unicorns_: That in the Repository of the electour of Saxone is plain and not hollow, and is believed to be a true Land _Unicorns_ Horn. _Albertus Magnus_ describeth one ten foot long, and at the base about thirteen inches compass: And that of _Antwerp_ which _Goropius Becanus_ describeth, is not much inferiour unto it; which best agree unto the descriptions of the _Sea-Unicorns_; for these, as _Olaus_ affirmeth, are of that strength and bigness, as able to penetrate the ribs of ships. The same is more probable, because it was brought from Island, from whence, as _Becanus_ affirmeth, three other were brought in his days: And we have heard of some which have been found by the Sea-side, and brought unto us from _America_. So that while we commend the _Unicorns_ Horn, and conceive it peculiar but unto one animal; under apprehension of the same vertue, we use very many; and commend that effect from all, which every one confineth unto some one he hath either seen or described.
