Why does unicorn have horn

Unicorn is a magical creature, so there is no certain proof of their biology. We can study different sources, though, and make our own conclusions based on research. Are unicorn horns actually made of gemstone? If so, is the whole horn made of gemstone or just the covering? I wonder if unicorn horns have a bone core, but the covering is gemstone instead of keratin.

Anyhow, unicorn horns are not like the horns of other animals. Unicorns are able to glow their horns, and they are able to use their horns for healing. Drinking from a horn of a unicorn is also supposed to relieve stomach aches and epilepsy. Even if the water was not contaminated in the first place, the unicorn seems to do some magic by dipping his horn in the water. Even early Christian writers mentioned the healing powers of unicorn horns. In a Christian book Physiologus , there is a story about a snake poisoning a river, and a unicorn that purifies the water with its horn.

In the Middle Ages , people highly valued unicorn horn cups. Actually, these cups were made of rhinoceros horn or narwhal tusk. However, people believed these were unicorn horns. In the s, there were newspapers in London advertising healing liquids and pills made of unicorn horns.

The royalty was also attracted to unicorn horns. The Throne Chair of Denmark is made of unicorn horns, as well as the imperial crown of the Austrian Empire.

Unicorn horns were also exposed in cabinets of curiosity. Obviously, most of these horns were likely narwhal tusks. It does not work as a talisman for humans. Therefore, the historical artifacts made of unicorn horns or narwhal tusk had no magical properties. Unicorns can indeed purify water using their horns.

But that is because the unicorns are using their horns for that. Drinking from a unicorn horn would do nothing because then it would be just like any other horn. The same applies to the healing powers of unicorn horns. Unicorns can heal a wound by touching it with their horn. Again, that is because the unicorn is doing the healing. Unicorn horns have intrigued people throughout history.

People used to believe unicorn horns can cure diseases and purify water. In the Middle Ages, cups made of unicorn horn were highly valued, since people believed drinking from one would protect from poisoning. Up until the 17th century, liquids and pills made of unicorn horns were widely sold as medicine.

Artifacts made of unicorn horns also attracted royalty. In reality, most of the historical objects made of unicorn horns were actually made of the narwhal tusk. A horn is the most magical part of a unicorn, and it is believed to be made of gemstone. Unicorns can glow their horns, and they can indeed heal wounds and purify water using their horns.

No-one knows exactly what a unicorn looks like but the artist who decorated this maiolica plate in the collection of the Fitzwilliam Museum: acc. The youthful rider, who sits astride a richly embroidered cloth, is dwarfed by the impressive size of his prancing steed. The scene is taken from a set of woodcuts and the letter H marks its place in the narrative.

The plates are thought to have been produced by a workshop in Cafaggiolo, not far from Florence. In fact, they were a ferocious addition to the ranks of mythical beasts in classical texts.

Pliny the Elder described the unicorn thus:. From these chimerical beginnings, the unicorn took a variety of directions in terms of both appearance and symbolism. It became an emblem for Christ in the Middle Ages and was often used in heraldry from the 15th century onwards.

The lion and the unicorn are the symbols of the UK with the lion representing England and the unicorn Scotland. The Fitzwilliam Museum collection abounds with unicorns. A Flemish Book of Hours, dating from , shows the Annunciation. Mary sits in a walled garden symbolic of her virginity and a white unicorn rests its horn in her lap. God the Father peeps out of a burning bush behind her and, beyond the garden, Gabriel blows a hunting horn.

A 15th-century illuminated manuscript — a French translation of a 13th-century encyclopaedia — depicts a unicorn in the Garden of Eden before the Fall of Man. Might this be the reason for unicorn horns? Interesting thing is also the evolution of horses and rhinos.

The actually both belong to the Perissodactyla order - which means that they are not that distant! Source Saola is almost as enigmatic as unicorn. This creature related to cattle, sometimes named "Asian unicorn", possesses a pair of parallel straight horns about 50 cm in length.

However, they were never seen in person by a scientist! They are extremely rare, critically endangered and live in the remote Annamite mountains.

Why do they have horns? Maybe for the same reason as unicorns. So, hopefully you did all learn something new today! Even though the subject was a bit silly. OK, It was very silly. See you soon. Unicorn — Wikipedia article Unicorn horn — Wikipedia article Narwhal — Wikipedia article The evolutionary biology of the unicorn!

Hey jepper that was such a great piece of writing. Keep it up. Don't assume unicorns wouldn't hunt. Come to think of it, a variation on the drop bear might even be feasible, just don't call them drop bears I guess.

The point is that when you introduce a fictional species, you might as well invent its ecosystem too. Bear in mind that the image of the unicorn you quote is based on artefacts which were thought at the time to be unicorn horns, but which we now know to be narwhal tusks. So a "practical" unicorn could have a much shorter horn see the Wikipedia article for some alternative illustrations and possibly positioned better. Medieval bestiaries had some very odd ideas about real animals, so if it turned out that unicorns were real you would expect that the bestiaries would have got some of it wrong.

Unicorn horns take years to grow, but once they are fully grown and the animal is mature, the unicorn diet changes to include meat.

Having no hands, unicorns use their horns like a modern day shish kabob skewers. Unicorns that fail to grow a horn sufficiently long enough to cook meat will often times catch fire.

So cooking meat on their horns is part of the natural evolutionary selective process. Only the most fit get to eat tasty kabobs and the rest turn into a pile of charred flesh. Perhaps the unicorn's horn is placed higher on the head to allow it to align with the vertebrae and thereby reinforce a blow.

It may be difficult to wield such a long weapon defensively, so maybe the unicorn is aggressive and attacks other unicorns or some other animal it perceives as a threat or as inferior to itself. Then having the long horn aligned with the spine would be beneficial in a charge. Additionally, if the horn is long it will also be heavy, and portions of horn farther out will apply more torque to the animal's neck. Having the horn on the nose may strain the unicorn's neck, and so placing it closer to the central support of the neck may make it easier to tote as well.

To be sufficiently sturdy and flexible, the horn would possibly have to be made of some unusual material that a horn typically wouldn't be made out of. After all, humans consume and absorb iron through different foods. Taken from here on deviantart , image copyright of AdamSteve Taken from here on cafepress , design by Niadra. As some of the repliers have pointed out here, there are animals that are thought to have had a single, large horn in the middle of the forehead, such as the toxodont Trigodon or the rhinoceros Elasmotherium.

There is another toxodont, Hoffstetterius , that has an even more pronounced base for a horn core. Kubanochoerus is an extinct pig that has a very pronounced projection of bone in the center of the skull.

No one knows what it was used for. There is also an extinct bovid, Tsaidmotherium , that has an asymmetrical set of horns with one being placed close to the center of the skull near the forehead. Ironically it seems to be a member of the same group that includes one of the possible real-life inspirations for the unicorn, the chiru Pantholops hodgsonii. Many sets of plate armor for horses also have spikes set in the middle of the forehead, though whether that is for function or aesthetic purposes I do not know.

Chris Lavers goes into some details at to what a single horn in the middle of the forehead might be useful for in his book The Natural History of Unicorns. Similar to some other repliers here, he mentions that a single, straight horn in the middle of the forehead would be much better for spearing and thrusting than a typical bovid horn. However, he also provides some direct observations that support this.

In some parts of Africa, the horns of cattle are artificially manipulated during growth for aesthetic purposes. Some calves have their horns manipulated so they point straight up through the middle of the forehead, rather than projecting out to the side. As adults, these bulls are oftentimes dominant in competing with other males over access to females because they can be much more aggressive in fights due to their forward-pointing horn structure, and they do seem to fight with a thrusting motion rather than locking horns.

I remember there was some suggestion that horns in the middle of the forehead were hard to develop because of how horn cores usually develop at the boundary between two bones or something. I think it was in the same book, but I am not sure. Notably in horned toxodonts and Elasmotherium the horn is thought to have been keratinous. As people have pointed out, a horn in the center of the forehead would be much better suited for charging behavior because it is aligned with the spine.

I'd like to add that a horn or plate in-like with the spine was one of the lines of evidence that led people to think that pachycephalosaurs butted heads, and while direct headbutting is controversial it is pretty clear they were using their heads to hit something. Plus a lot of animals often have large sinuses in the forehead region that can act as good shock absorbers when the horn makes contact. A unicorn would almost certainly have a ridged horn. Those ridges in living horned animals aren't really used for anything but are the result of natural periodic growth due to the fact that the horn grows from the base continually throughout life in contrast to deer antlers or pronghorn prongs which are shed annually.

Mark Witton goes into some detail how this works here. The ridges don't usually prevent slipping. An horned ungulate usually doesn't want to get its horns stuck in a struggling predator, the purpose of the horn is to keep the predator away from its softer body by prodding it with the pointy end.

They're not designed to kill in the same way that spears are. The really gracile, ridgeless, spiral-shaped, white horn you see in a lot of unicorn depictions is clearly modelled after a narwhal tusk, which is a modified tooth. Narwhal tusk was often sold as unicorn horn in medevial Europe, though the actual legend likely draw more from Asiatic rhinoceroses and the chiru which has close-set horns that can look like a single horn from a distance.

A "real" unicorn almost certainly wouldn't look like a narwhal tusk, unless the horn was grown and shed annually like a deer antler which have no covering. Otherwise it would probably be brownish or black due to a keratin covering , ridged, non-spiraled, and possibly much more robust. There is also the possibility that a unicorn doesn't just have horns, but tusks as well, and the horns and tusks are used for different tasks.

There is a tendency in many ungulates to lose tusks when horns are developed this is seen in ruminants, brontotheres, and rhinoceroses, among others but there are exceptions. The Indian Rhinoceros mostly uses its tusks in fights between members of the same species and tends to use its horn for defense against predators, or so I've heard.

Kubanochoerus and horned toxodonts also have both tusks and horns. A unicorn could use tusks or enlarged canines in social disputes, but then use the horn in a thrusting or jabbing motion against predators.

The comparison would be like a lance or a spear compared to the shorter, more sword-like reach of a cow or goat horn. The horn may not be sticking straight up as in popular depictions, but angled forward so that the frontal, parietal, and nasal bones can form a better base of support.

A really long horn would force predators to stay further back to avoid getting stabbed, so long as it's not so long that it interferes with feeding. Getting struck by the side of the horn probably wouldn't be fun either.
