The unicorn is a mythical creature. Strong, wild, and fierce, it was impossible to tame by man. Plinie, the Roman naturalist records it as “a very ferocious beast, similar in the rest of its body to a horse, with the head of a deer, the feet of an elephant, the tail of a boar, a deep, bellowing voice, and a single black horn, two cubits in length, standing out in the middle of its forehead.”
The unicorn is an archetypal monster, present both in eastern and western mythology. In the Bible, God is said to have the strength of a unicorn. [Num 23:22 & 24:8]; The warlike fierceness of the unicorn is referred to when Ephraim and Manasseh are described as being like the horns of unicorns. [Deu 33:17]; The terrifying destruction of Idumea is completed when God sends unicorns and wild bulls to attack the people. [Isa 34:8 see also Psa. 92:10 & Psa 22:21]
Modern zoologists have generally disbelieved the existence of the unicorn. Yet there are animals bearing on their heads a bony protuberance more or less like a horn, which may have given rise to the story. The rhinoceros horn, as it is called, is such a protuberance, though it does not exceed a few inches in height, and is far from agreeing with the descriptions of the horn of the unicorn. The nearest approach to a horn in the middle of the forehead is exhibited in the bony protuberance on the forehead of the giraffe; but this also is short and blunt, and is not the only horn of the animal, but a third horn, standing in front of the two others.
