Beyond this fact, it is hard to define a unicorn. A multitude of different unicorn species populated the mythology of nations in Europe, Asia and Africa. The original unicorn seems to be the one spoken of in myths from India. It was often thought to live in inaccessible, mountainous terrain such as the mountains of Tibet. This animal seemed like a wild ass or antelope with one horn. The unicorn of China combined body parts from several animals and was perhaps the smallest unicorn. Its horn was short, soft and harmless.

Because of its single nose horn, the rhinoceros was often called a unicorn. Technically, it fits the requirement of having a single, natural, centered horn, but it does not look like the general type of unicorn that the largest number of myths have focused on. Despite this, the rhinoceros is often trotted out as an all-purpose explanation for all unicorn sightings, including those in Europe, where Medieval peasants would not have had a chance to see any such creature.

The khara of Persia was a giant donkey with a single horn growing from its forehead. It had only three legs, but six eyes. It had protective powers of much the same sort as unicorns the world over, and it was important in the Zoroastrian religion.

The unicorn of European myth was smaller than a horse and had characteristics combining a horse, goat and deer. It always had dainty cloven hooves, not heavy horse-hooves. The idea that a unicorn looks exactly like a horse except for its horn is an invention of modern fantasy art.

Unicorn sightings from many areas of the world have caught the attention of explorers and scientists for hundreds of years. For a long time, people were generally expecting that unicorns were going to be discovered one of these days. Unicorns always seemed to be just around the corner, and there were many relatively unexplored corners of the world where they presumably might lurk.

Eventually, this expectation faded. Unicorns did not get discovered, and the number of sightings faded too. Yet, there are still some cryptozoologists today who think that so much hoopla could not have been based on nothing.

Once again, we can trot out a presumably extinct animal in order to "explain" a cryptozoological oddity. Europe was once home to an antelope that had its two horns set so close together on its head that paleontologists believe that a single horn-sheath probably covered both horns, thus converting them into a single central horn. There is no fossil evidence for this beast surviving beyond a time that was a million years ago, but this proves little. In the life of a species, a million years is a relatively short time. There are many perfectly real modern antelopes that we have no fossil record for. If this antelope had lived long enough to have been around sometime during the last few thousand years, it could presumably be the inspiration for unicorns. Some researchers have proposed that another cryptid, the Vu Quang ox, inspired the ki-lin, China's unicorn. A presumably extinct prehistoric Eurasian rhinoceros, Elasmotherium, has also been suggested as a basis for the unicorn myth.
