Re’em
Also Known As: Hebrew רְאֵם, reʾem; plural re’emim; cognate with Akkadian rīmu; rendered monokeros in the Septuagint and unicornis in the Vulgate, “unicorn” in the King James Bible, and “wild ox” in most modern translations
Region/Culture: West Asia/Middle East
Mythos: Jewish Mythology, Christian Mythology
Primary Type/Nature: Monsters and Beasts
Mythical Attributes: A colossal wild ox of untameable strength, carrying great upswept horns and, in later legend, swelling to the size of a mountain.
Role in Mythos: In the Hebrew Bible the re’em is the standing emblem of God-given, unconquerable power, and in rabbinic legend it becomes a giant beast that outlives the Flood.
Relation to Humans: No rope, yoke, or plow can bind the re’em to human use, and scripture invokes it precisely as the strength that answers to no one. In the legends it nearly kills the young David and can only be escaped, never mastered.
On the dry uplands where the Jordan runs down toward the salt sea, there was said to walk a beast that no rope could hold and no farmer could yoke. Its horns rose in twin curves toward the sky, and the ground gave slightly under the weight of it. The Hebrew Bible calls this animal the re’em, and it appears nine times across the oldest books, never as a story in itself, always as the last word in an argument about strength. When the poets and prophets wanted an image for power that answered to no one, they reached for it.
The Book of Job puts the case most plainly. God asks whether the re’em will agree to serve, whether it will spend the night beside the manger, whether it can be bound with a rope in the furrow to break the clods behind a plow. The questions are rhetorical and a little cruel, because everyone listening knew the answer. You could tame the ox that pulled the cart and the ass that turned the mill, but not this one. It stood in the field on its own terms, and the field belonged to it for as long as it chose to stand there.
Physically the re’em was a wild ox, and a real one lies behind the legend. Most scholars now identify it with the aurochs, Bos primigenius, the towering dark-coated ancestor of domestic cattle that once ranged across Europe and the Near East, a bull that stood about as tall as a man at the shoulder and carried horns approaching a meter in length. The Akkadians knew the same animal as the rīmu and set it in glazed brick on the gates of their cities. In Assyrian relief the beast is often shown in strict profile, so that its two great horns overlap into one, and this small habit of ancient art had enormous consequences. When the scriptures were rendered into Greek, the translators wrote monokeros, one-horn. The Latin Vulgate followed with unicornis. By the time the words reached the King James Bible in 1611, the untameable wild ox of the desert had become the unicorn, and generations of readers pictured a delicate horned horse where the poets had meant a wall of muscle and bone.
The rabbis took the beast in the other direction entirely. In the Talmud the re’em swells past any natural scale. Rabbah bar bar Hana, a great teller of tall stories, claimed to have seen a re’em only one day old that was already as large as Mount Tabor. Its neck alone stretched three parasangs, some ten miles, and when it let its dung fall into the Jordan the river was dammed. This is folklore enjoying itself, and it knows it. But underneath the comedy sits a real theological puzzle, and the sages chased it seriously.
The puzzle was the Flood. If the re’em was the size of a mountain, it could never have fit inside Noah’s ark, and yet here it plainly still was. The teachers of tractate Zevachim worked at the problem. One held that Noah took aboard only the young calves, small enough to shelter. Another answered that even the calves were too vast, so Noah tied the animal by its horn to the outside of the ark and let it swim behind through the whole year of rain, its nostrils above the water. The giant Og, last of an older race, was said to have ridden out the deluge perched on the creature’s back, sworn to Noah in exchange for his passage. The waters that drowned the world could not quite drown the re’em. It came through at the end of the tether.
The strangest of its stories fastens onto David. Before he was king, when he still kept his father’s sheep, the boy is said to have come upon what he took for a low hill and climbed to the top of it to rest. The hill was a sleeping re’em. It woke and rose, and David went up with it until his hand could nearly brush the sky, and there he clung, praying, promising God a temple as high as the animal’s horn if he were only brought down alive. God sent a lion, king of the beasts, and at the sight of it the re’em lowered itself in submission, and David slid to the ground. There is no version in which he tames the thing. He only survives it.
Its powers all come down to a single quality carried to its limit: it is strong past the point of any use. It cannot be harnessed, cannot be penned, cannot be made to work or fight for anyone. That same excess is its only real weakness, because a creature too large to fit in the ark is a creature the world has no easy place for. The blessing Moses spoke over the house of Joseph called their horns the horns of a re’em, goring the nations to the ends of the earth, and that is the shape the animal keeps in scripture. Not a hunter, not a devil. Just force, standing in a field, waiting.
The aurochs that stood behind it did not last. Hunted and crowded out of its forests, the last of them died in a Polish woodland in 1627. The beast that could not be tamed was simply outlived.
Frequently Asked Questions
What is the Re’em?
The Re’em is a wild ox mentioned nine times in the Hebrew Bible, used as a symbol of immense, untameable strength. Modern scholars identify the original animal with the aurochs, the giant extinct wild cattle of Europe and the Near East, while later Jewish legend reimagined it as a mountain-sized beast.
Is the Re’em a unicorn?
The Re’em became the “unicorn” through translation, not through its original meaning. Ancient Greek translators rendered the Hebrew word as monokeros (“one-horn”), the Latin Vulgate used unicornis, and the King James Bible printed “unicorn,” even though the re’em was a two-horned wild ox often shown single-horned in profile in Near Eastern art.
How big is the Re’em in Jewish legend?
In the Talmud the Re’em is described at enormous scale, most famously by Rabbah bar bar Hana, who claimed to have seen a one-day-old re’em as large as Mount Tabor. Its neck was said to stretch three parasangs, and its dung was said to dam the Jordan River.
How did the Re’em survive Noah’s flood?
Because the Re’em was too large for the ark, the rabbis offered several solutions. Some said Noah brought only its young calves aboard, while others said Noah tied the beast to the outside of the ark by its horn and let it swim behind through the flood, with the giant Og riding on its back.
What does the Re’em symbolize?
The Re’em symbolizes raw, God-given power that cannot be controlled by human hands. Biblical writers invoke it in Job, the Psalms, and the blessings of Moses as an image of strength that no one can yoke, tame, or set to work.
