An animal called the "re'em" () is mentioned in several places in the Hebrew Bible, often as a metaphor representing strength. The allusions to the "re'em" as a wild, untamable animal of great strength and agility, with mighty horn or horns best fit the aurochs ("Bos primigenius"); this view is further supported by the Assyrian cognate word "rimu," which is often used as a metaphor of strength, and is depicted as a powerful, fierce, wild mountain bull with large horns. This animal was often depicted in ancient Mesopotamian art in profile, with only one horn visible.
