Odd translation. Mine says "wild ox."
Assyrian archaeology provides one other possible solution to the unicorn identity crisis. The biblical unicorn could have been an aurochs (a kind of wild ox known to the Assyrians as rimu). The aurochs’s horns were symmetrical and often appeared as one in profile, as can be seen on Ashurnasirpal II’s palace relief and Esarhaddon’s stone prism. Fighting rimu was a popular sport for Assyrian kings. On a broken obelisk, for instance, Tiglath-Pileser I boasted of slaying them in the Lebanese mountains. Extinct since about 1627, aurochs, Bos primigenius, were huge bovine creatures. Julius Caesar described them in his Gallic Wars as,
. . . a little below the elephant in size, and of the appearance, color, and shape of a bull. Their strength and speed are extraordinary; they spare neither man nor wild beast which they have espied. . . . Not even when taken very young can they be rendered familiar to men and tamed. The size, shape, and appearance of their horns differ much from the horns of our oxen. These they anxiously seek after, and bind at the tips with silver, and use as cups at their most sumptuous entertainments. https://answersingenesis.org/extinct-animals/unicorns-in-the-bible/
