the king james version of the bible mentions unicorns, but at that time one horned rinos were called unicorns.
f you get an old 1828 Noah Webster’s Dictionary, which is the very first edition dictionary that Webster came out with about 200 years ago, and look up the word “unicorn” it says:
Unicorn – An animal with one horn; the monoceros. this name is often applied to the rhinoceros.
(This 1828 dictionary can be accessed free online. Just go to Google.com and type in “Noah Webster 1828” and it will be one of the first links that pop up.)
Notice how this 200-year-old definition of the word “unicorn” says absolutely nothing about a horse. It says nothing about a horse-like animal, or a mythical animal, or a fictitious creature. It says absolutely nothing about mythology whatsoever. But rather, it says that this is a name that is often applied to the rhinoceros.
Now, anyone who has ever seen a rhinoceros knows that a rhino has two horns — a larger one up front, and a smaller one behind. So, how could a rhinoceros be considered a unicorn?
Well, if you look up the word “rhinoceros” in the same dictionary it says:
Rhinoceros – A genus of quadrupeds of two species, one of which, the unicorn, has a single horn growing almost erect from the nose. This animal when full grown, is said to be 12 feet in length. There is another species with two horns, the bicornis. They are natives of Asia and Africa.
According to Noah Webster, back in the early 1800’s it was understood that there were two species of the rhinoceros. The one-horned species was called “unicorn,” and the two-horned species was called “bicornis.”
Today it is understood that there are five species of the rhinoceros, three of which have two horns, and two of which have one horn.
