There are many animals mentioned in the Scriptures which cannot be identified with any certainty, partly because their names occur only once or twice in the sacred writings, and partly because, when they are mentioned, the context affords no clue to their identity by giving any hint as to their appearance or habits. In such cases, although the translators would have done better if they had simply given the Hebrew word without endeavouring to identify it with any known animal, they may be excused for committing errors in their nomenclature. There is one animal, however, for which no such excuse can be found, and this is the Reêm of Scripture, translated as Unicorn in the authorized version. Now the word Reêm is mentioned seven times in the Old Testament, and is found, not in one, but several books, showing that it was an animal perfectly well known to those for whom the sacred books were written. It is twice mentioned in the Pentateuch, several times in the Psalms, once in the book of Job, once by Isaiah, and reference is once made to it in the historical books. In these various passages, abundant details are given of its aspect and habits, so that there is very little doubt as to the identity of the animal. The Septuagint translates Reêm by the word Monoceros, or the One-horned, which has been transferred to the Vulgate by the term Unicornis, a word having the same signification. In an age when scientific investigation was utterly neglected, such a translation would readily be accepted without cavil, and there is no doubt that the generality of those who read the passages in question accepted them as referring to the Unicorn of heraldry with which we, as Englishmen, are so familiar. I may perhaps mention briefly that such an animal is a physiological impossibility, and that the Unicorn of the fables was a mere compound of an antelope, a horse, and a narwhal. The tusks or teeth of the narwhal were in former days exhibited as horns of the Unicorn, and so precious were they that one of them was laid up in the cathedral of St. Denis, and two in the treasury of St. Mark's at Venice, all of which were exhibited in the year 1658 as veritable Unicorns' horns. The physiological difficulty above mentioned seems to have troubled the minds of the old writers, who saw that an ivory horn had no business to grow upon the junction of the two bones of the skull, and yet felt themselves bound to acknowledge that such an animal did really exist. They therefore put themselves to vast trouble in accounting for such a phenomenon, and, in their determination to believe in the animal, invented theories nearly as wonderful as the existence of the Unicorn itself.
