The oryx next became the subject of conversation, and Swartboy could tell more about it than any one. Of the oryx Congo knew very little, as the region most frequented by this beautiful antelope lies farther west than the country of the Kaffir tribes. Its headquarters are in the land of the Namaquas, though it is thinly scattered all around the borders of the Great Kalihari Desert.

The oryx is a desert-dwelling antelope, can live without water, and grows fat even on the plants that thinly vegetate over the barren soil. It is a bold creature—often beats off the lion, or kills him by impalement on its long bayonet-like horns. Of the truth of this fact our yägers had that day had proof. The oryx when hunted does not, like many other antelopes, make for either water or cover. It strikes in a straight line for its desert home, trusting to its heels for safety. And its confidence in them is seldom misplaced. A swift horse alone can overtake and bring it to a stand; unless it be very fat, and then it is more easily “blown.”

An interesting point occurred in the conversation about the oryx.

Arend and some of the others had read in several books of travellers that the oryx was supposed to be the fabled “unicorn,” derived from Egyptian sculptures. They asked if this was the case. Their question was not put to Swartboy, you may be sure, but to Hans the naturalist, of course.

Hans regarded the supposition as a very silly one. A mere fancy of some early South African traveller, that had been repeated, parrot-like, in the books of other travellers and the writings of several closet-naturalists. The supposition of the oryx being the original of the unicorn rested only upon the fact that its horns when seen en profile appear as but one; and the unicorn is so figured on the Egyptian sculptures. Now this argument can be advanced in favour of several other antelopes, and therefore falls at once to the ground as regards the oryx.

Hans mentioned several reasons why the gemsbok could not be the “fabled unicorn.” Its form, and particularly the shape of its head, are quite unlike the sculptures of that famous creature. Its horns, both in length and “set,” even when seen en profile, differ altogether from that of the unicorn, which points forward, whereas the horns of the oryx extend backward almost horizontally, and sometimes even touching the flanks of the animal.

“No,” continued Hans; “if the Egyptian unicorn be not a fable—if it be the representation of any animal in Africa, that animal is the gnoo; and I regard it as something singular that the resemblance between the gnoo—I mean the common species, not the ‘brindled’—and the fabled unicorn, has not long since been noticed by naturalists and travellers.

“I should fancy that no one could look upon the pictures of both without being struck by this resemblance. Their forms, both of head and body, the elegant rounding of limb, the split hoof, the long tufted tails, the proud arching necks, with full flowing mane,—all these points go to show that the gnoo was copied for the unicorn. The one horn is the only circumstance that appears to invalidate my theory, but even in this respect the gnoo bears a much greater resemblance to the unicorn than does the oryx. The horns of the gnoo are set in such a manner that it often appears a unicorn. Their tips do not rise above the level of the skull; and in consequence of this, and also from the manner in which the animal frequently carries its head, only one horn is visible, the other being, inconspicuous against the dark ground of the head and mane. Often only half the horn appears at a distance, and is then seen pointing forward and ‘set,’ very similarly to the brow ornaments of the unicorn.

“The horn of the unicorn is usually represented quite straight in modern paintings; but this is not correct, according to the Egyptian sculpture, where a curve is given,—a positive imitation of the curve in the horns of the oryx! Even though it were straight, this would scarce invalidate my theory, for the horns of the young oryx are straight also, and we might suppose a young one to be represented.

“I do not beg the question in this way, however,” continued Hans, “for I know that whatever animal the Egyptians meant on their sculptures must have been well known to them, and it is not likely that they would have pictured a specimen of immature age. The singular character of the gnoo, its odd and eccentric habits, as well as the eccentricity of its form and appearance, must have drawn attention to it from the earliest times, and such an animal would not fail to be pictured by the Egyptians. As to the one horn, I regard the existence of that, either as the result of imperfect observation on the part of the Egyptian sculptors, or, what is more likely, a want of knowledge of their art. Egyptian sculpture is at best but a rude affair, and the peculiar curve and set of the oryx horns are difficult to depict. Even in this very hour of high art, our painters do not give the most correct delineation of the head of a gemsbok. So, you see, I make out a tolerably clear case, that the gnoo of South Africa is the original of that mysterious celebrity—the unicorn.”
