There has been much discussion as to the identity of the animal referred to in many passages of the Bible, the Hebrew name of which, _Reem_, has been translated "unicorn." Mr. W. Smith considers that a species of rhinoceros could not have been indicated, as it is spoken of in one passage as a sacrificial animal, whereas the ceremonial ritual of the Jews forbade the use of any animal not possessing the double qualifications of chewing the cud and being cloven-footed. The qualities attributed to it are great strength, an indomitable disposition, fierce nature, and an active and playful disposition when young. He considers that the passage, Deut. xxxiii. 17, should be rendered "his horns are like the horns of a unicorn," and not, as it is given, "horns of unicorns"; and is of opinion that some species of wild ox is intended. Among profane Western authors we first find the unicorn referred to by Ctesias, who describes it as having one horn, a cubit long. Herodotus also mentions it in the passage,[282] "For the eastern side of Libya, where the wanderers dwell, is low and sandy, as far as the river Triton; but westward of that, the land of the husbandmen is very hilly and abounds with forests and wild beasts, for this is the tract in which the huge serpents are found, and the lions, the elephants, the bears, the aspicks, and the horned asses"; and again, "Among the wanderers are none of these, but quite other animals, as antelopes, &c. &c., and asses, not of the horned sort, but of a kind which does not need to drink." Aristotle[283] mentions two unicorn animals. "There are only a few [animals] that have a solid hoof and one horn, as the Indian ass and the oryx." Pliny[284] tells us that the Orsæan Indians hunt down a very fierce animal called the monoceros, which has the head of the stag, the feet of the elephant, and the tail of the boar, while the rest of the body is like that of the horse. It makes a deep lowing noise, and has a single black horn, projecting from the middle of its forehead, and two cubits in length. This animal, it is said, cannot be taken alive. In speaking of the Indian ass, he says,[285] "the Indian ass is only a one-horned animal"; and of the oryx of Africa,[286] "the oryx is both one-horned and cloven-footed." Ælian[287] transfers the locality back again from Africa to Asia, and it may be presumed, in the following quotation, that he indicates the country north of the Himalaya, Thibet, and Tartary, which still has the reputation of being one of the homes of the unicorn. "They say that there are mountains in the innermost regions of India inaccessible to men, and full of wild beasts; where those creatures which with us are domesticated, such as sheep, dogs, goats, and cattle, range about at their own free will, free from any charge by a shepherd or herdsman.
