Over the past five years or so, unicorns have gained sudden popularity in the Western world. It is almost impossible to go shopping without seeing one of the mythical creatures, whether it be on a t-shirt, a card, a toy, a cake or even chicken nuggets. In popular culture, unicorns are a pretty, make-believe character with which many children (and even adults) are fascinated. This commercial unicorn, however, has its roots in ancient mythology. For hundreds, if not thousands of years unicorns have been described in natural histories and folktales.
Unicorns are the stuff of legends and, as many people agree, probably never existed. Yet, who came up with the idea of the unicorn? How did a horse with a horn on its head become a thing? Ancient accounts of natural history include the unicorn, so perhaps they did exist, or at least something similar to our modern idea of the unicorn.

Whether real or not, unicorns are recognised from a single horn protruding from their forehead. The horn, known as an alicorn, is the source of their magical power, usually used for purification and healing. Typically, they resemble a white horse and have been used as a symbol of purity and grace. Despite their elegance, they are wild, woodland creatures and, according to some legends, only a virgin could tame them.
The earliest written description of a unicorn comes from a book written in the 5th century BC. Indica or Indika contains a mix of dubious stories and myths about the East, possibly India, compiled by the Greek physician and historian Ctesias the Cnidian. Ctesias was the physician to the king of the Achaemenid Empire, Artaxerxes II (c435-358 BC). As part of his role, Ctesias accompanied the king on various expeditions and battles and, therefore, became well acquainted with the neighbouring lands. This allowed the physician to pen treatises on rivers and lands, including Persia and India. Some of the information is based on first-hand experience, however, the rest was pieced together through various stories told by travellers.
Indica, which only remains in fragments, is generally considered to be pure fantasy. It contains many of the strange beliefs the Persians had about India, including that the country was full of riches and gold, artisans, philosophers, god-like people and, of course, unicorns.

Unicorn IV (Ctesias)- Cecilia Caride
Ctesias’ unicorn is described as a white horse with a purple head and blue eyes. The horn projecting from the forehead was approximately 27 inches long and coloured white at the base, black in the middle and red at the point. As well as being the first person to describe a unicorn, Ctesias was the first to attribute magic to a unicorn’s horn.
“No creature, neither the horse or any other, could overtake it.”
– Ctesias
It is now thought Ctesias’ unicorn may have resulted from a mixture of animal descriptions, such as the Indian rhinoceros and an ass. Alternatively, there is the smallest of chances it may have been real, however, the other creatures described in Indica suggest otherwise, for example, people with one leg and feet so big they could be used as umbrellas, and manticores – red creatures with human faces, three rows of teeth, and scorpion tails. On the other hand, some of the information proved to be true, for instance, Indian elephants, monkeys, Indian customs, a large population and the Indus river.
Indica remained the main source of information about India for people in the Mediterranean until the 2nd century AD when the book was satirised by Lucian of Samosata (c125-c180). Lucian claimed Ctesias to be a liar and depicted him as being condemned to a special part of hell to pay for his sins.
Although Ctesias may have provided the earliest written description of the unicorn, evidence that the creatures may have “existed” long before then has been discovered in South Asia. Several seals depicting what looks like a unicorn have been unearthed in the land once belonging to the Indus Valley Civilisation. They date back to the Bronze Age, which lasted from 3300 BC until 1200 BC.
These seals are thought to have belonged to people of high social rank, however, little else can be gleaned from them. There is also the argument the creature on the seal was not intended to be a unicorn but an auroch. Now extinct, aurochs were a species of large cattle that inhabited areas of Europe, Asia and Africa. Skeletons of the creatures reveal they had two horns, one on either side of their head. Always drawn in profile, the creatures on the seals could have been an auroch with one horn hidden from view by the other.
Despite the theories that the seals were not unicorns and Ctesias was a fraud, many other ancient texts mention the unicorn. De natura animalium (On the Nature of Animals) was a collection of seventeen books about natural history compiled by Aelian (Claudius Aelianus, 175-235 AD). Aelian was a Roman author and teacher of rhetoric (persuasion, grammar and logic) who was also fluent in the Greek language. The majority of the anecdotes in the collection were taken from other sources, including Ctesias. Aelian stated India produced one-horned horses known as the monoceros. Another name for the monoceros was cartazonos, however, this may be the Greek form of the Arabic word karkadann, which means “rhinoceros.”
Aelian also quotes Pliny the Elder (AD 23-79), who wrote the encyclopedia Naturalis Historia (Natural History). Pliny wrote about about “a very fierce animal called the monoceros which has the head of the stag, the feet of the elephant, and the tail of the boar, while the rest of the body is like that of the horse; it makes a deep lowing noise, and has a single black horn, which projects from the middle of its forehead, two cubits [900 mm, 35 inches] in length.” He also claimed the oryx antelope and Indian ox were one-horned creatures, as did Aristotle (384-322 BC) centuries beforehand. The Greek philosopher Strabo (64 BC-AD 24) also mentioned one-horned horses with stag-like heads.
In the 16th century, Swiss naturalist Conrad Gessner (1516-65) produced a Latin translation of Aelian’s work titled Historia Animalium. Although he attempted to sort fact from fiction, Gessner still included the unicorn, which he had only heard about from medieval bestiaries. Gessner made it clear that he doubted some of the information, however, included it anyway since he believed it could teach moral lessons and divine truths. He went into as much detail into mythological creatures as he did about real animals. Mythological creatures that featured in the book included unicorns, mermaids, sea bishops and ichthyocentaur – creatures with the upper body of a human, the front legs of a horse and the tail of a fish.
As early as the 6th century, theories were expressed as to why unicorns were rarely seen. Cosmas Indicopleustes, a 6th-century Greek merchant from Alexandria of Egypt reported, “it is impossible to take this ferocious beast alive; and that all its strength lies in its horn. When it finds itself pursued and in danger of capture, it throws itself from a precipice, and turns so aptly in falling, that it receives all the shock upon the horn, and so escapes safe and sound.” Cosmos also wrote a series of books about scientific geography known collectively as Christian Topography. Cosmas aimed to convince people of his theory that the earth was modelled on the tabernacle described to Moses by God in the Book of Exodus. His view was the earth was flat and the heavens formed the shape of a box with a curved lid.
Cosmas was not the only Christian writer to describe the legendary unicorn. Many authors of bestiaries (books about beasts), including the aforementioned Conrad Gessner, relied on the Christian text Physiologus, which was compiled in Greece during the 2nd Century AD. Although the unknown author introduces each creature by saying “the naturalist says” or something similar, each chapter is told more like a story than a statement of fact. Many of these stories relate in some way to the Bible, particularly the resurrection of Christ, for example, the phoenix, which burns itself to death but rises from the ashes three days later.
Physiologus devotes entire chapters to individual creatures, some real and some mythological, beginning with the lion and ending with the eel. Other creatures include hedgehogs, ostriches, panthers, elephants, doves, serpents, pelicans, phoenixes and, rather strangely, Amos the Prophet. The unicorn is found in chapter 36 and is the source of the legend that only a maiden can tame the unicorn. This allegory refers to the Virgin Mary upon whose lap the unicorn laid its head and slept.

Many religious artworks concerning the Inception of the Virgin Mary are inspired by the story in Physiologus. In some interpretations, the unicorn represents Christ and his relationship with the Virgin, his mother. Secular writers have developed this story into myths about chaste love and faithful marriage. Even the polymath Leonardo da Vinci (1452-1519) explored the tale of the unicorn, stating in one of his notebooks, “The unicorn, through its intemperance and not knowing how to control itself, for the love it bears to fair maidens forgets its ferocity and wildness; and laying aside all fear it will go up to a seated damsel and go to sleep in her lap, and thus the hunters take it.”
The Italian explorer Marco Polo (1254-1324) also alluded to the myths about unicorns, however, he also called them ugly, brutes, and reported they “spend their time by preference wallowing in mud and slime.” It appears he may have mistaken a rhinoceros for a unicorn.
The secular take on the myth of the unicorn and the virgin, as noted by Da Vinci, led to the story The Hunt of the Unicorn. The tale involves a group of hunters who are struggling to capture a unicorn until a young maiden offers her assistance. Since virgins can tame unicorns, the creature came and rested its head upon her lap, allowing the hunters to capture it.
The Hunt of the Unicorn was first recorded on a series of tapestries in Paris at the turn of the 16th century. It is speculated they were commissioned by Anne of Brittany (1477-1541) to celebrate her marriage to Louis XII (1462-1515). Each tapestry, seven in total, tells a different part of the story:
- The Start of the Hunt
- The Unicorn at the Fountain
- The Unicorn Attacked
- The Unicorn Defending Himself
- The Unicorn Is Captured by the Virgin
- The Unicorn Killed and Brought to the Castle
- The Unicorn in Captivity
Despite being based on a pagan story, scholars have identified Christian symbolism in the tapestries. The unicorn is Christ and its death is the crucifixion. As you will notice from the order of the seven tapestries, the unicorn’s death is not the final stage. In scene seven, despite remaining in captivity, the unicorn has returned to life, similar to Christ’s resurrection.
Another tapestry involving a unicorn is La Dame à la licorne (The Lady and the Unicorn), which was produced in Flanders in the 16th century. Five of the six tapestries depict one of the five senses: taste, hearing, sight, smell, and touch; with À mon seul désir being the title of the sixth. The latter translates as “my only desire” and has left many wondering its true meaning. A possible interpretation is the desire for love or understanding.
La Dame à la licorne does not tell a sequential story like The Hunt of the Unicorn, instead, it presents a meditation on earthly pleasures demonstrated through the five senses. Touch is demonstrated by the lady holding a banner in one hand and touching the unicorn’s horn with the other. Sweets represent taste, flowers for smell, a portative organ for hearing, and a mirror for sight.
The sixth tapestry shows the woman placing her pendant in a box. Some suggest this is an acknowledgement of the passions aroused by the other senses and free will. Others have put forward the idea that it represents a sixth sense: understanding. There is also the argument that there is no way of telling if the woman is putting the pendant in the box or retrieving it. It has been noticed, however, that this is the only tapestry in which the woman smiles.
La Dame à la licorne does not only feature a unicorn but also a lion. Both these creatures are used in heraldry to symbolise a country. The most famous use of these animals are for Scotland (unicorn) and England (lion). One legend claimed the unicorn was the natural enemy of the lion and would rather die than be captured. This represented Scotland’s desire to remain sovereign and unconquered. Of course, this all changed with the 1707 union of Scotland and England.
It is not certain where the idea that lions and unicorns were enemies originated, however, the legend is recorded in a nursery rhyme.
- The lion and the unicorn
- Were fighting for the crown
- The lion beat the unicorn
- All around the town.
- Some gave them white bread,
- And some gave them brown;
- Some gave them plum cake
- and drummed them out of town.
This rhyme featured in Lewis Carroll‘s (1832-98) 1871 novel Through the Looking-Glass, a sequel to Alice’s Adventures in Wonderland. A unicorn and a lion are seen fighting over the crown belonging to the White King. For comedic effect, Carroll alters the traditional characteristics of the animals, making the lion slow and stupid and the unicorn monstrous. When producing illustrations for the book, Sir John Tenniel (1820-1914) made caricatures of Benjamin Disraeli (1804-88) as the unicorn and William Ewart Gladstone (1809-98) as the lion in reference to their frequent parliamentary battles.
There are two common jokes about why unicorns may no longer exist. The first is the unicorns did not get on Noah’s ark in time (see video at the end of this article) and the second that they did get on the ark, but they were both males. Incidentally, unicorns are traditionally believed to be male and none of the myths, legends or bestiaries shed light on how they reproduce. The only claim about their nature is they are solitary creatures and can live for hundreds of years.

So, unicorns may not have been on Noah’s Ark, however, they are mentioned in the Bible. The Hebrew Bible mentions an animal called the re’em, an untamable animal of great strength and agility, with a horn. Unfortunately, it is generally believed the description was based upon the seals belonging to the Indus Valley Civilisation, which are now thought to be aurochs. Nonetheless, the King James Version of the Bible, first published in 1611, translates the word re’em as “unicorn”.
There are eight references to unicorns in the Old Testament. They are as follows:
- “God brought them out of Egypt; he hath as it were the strength of an unicorn.” – Numbers 23:22
- “God brought him forth out of Egypt; he hath as it were the strength of an unicorn.” – Numbers 24:8
- “His glory is like the firstling of his bullock, and his horns are like the horns of unicorns: with them he shall push the people together to the ends of the earth.” – Deuteronomy 33:17
- “Will the unicorn be willing to serve thee, or abide by thy crib? Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee? Wilt thou trust him, because his strength is great? or wilt thou leave thy labour to him? Wilt thou believe him, that he will bring home thy seed, and gather it into thy barn?” – Job 39:9–12
- “Save me from the lion’s mouth; for thou hast heard me from the horns of unicorns.” – Psalms 22:21
- “He maketh them [the cedars of Lebanon] also to skip like a calf; Lebanon and Sirion like a young unicorn.” – Psalms 29:6
- “But my horn shalt thou exalt like the horn of the unicorn: I shall be anointed with fresh oil.” – Psalms 92:10
- “And the unicorns shall come down with them, and the bullocks with their bulls; and their land shall be soaked with blood, and their dust made fat with fatness.” – Isaiah 34:7
Real or not, what makes a unicorn so interesting is the horn protruding from its forehead. The existence of unicorns was supposedly disproved in 1825 by Baron Georges Cuvier (1769-1832), a French naturalist and zoologist, the father of palaeontology. Cuvier declared it was impossible for any animal with a split hoof, such as a horse, to have a horn on top of its head. Before this claim, unicorn horns were a much sought but rare commodity.
Ancient writers such as Ctesias and Aelian recorded that a unicorn’s horn, made from a substance called alicorn, could be made into a vessel that when drunk from would protect against diseases and poisons. Other parts of the body of a unicorn were also considered to have medicinal properties. The 12th century Abbess Saint Hildegard of Bingen wrote a recipe for an ointment to cure leprosy. The ingredients included egg yolk and foie de licorne, also known as unicorn liver.
In Physiologus, the unicorn is said to be able to purify water with its horn. The book tells the story of a lake poisoned by a snake. None of the animals dared to go near the water to drink, however, when the unicorn appeared, it went straight to the water. With its horn, it made the sign of the cross in the water (remember Physiologus was a Christian text) and the poison was rendered harmless.
Over time, the horn of the unicorn was assigned many medicinal properties. These included cures for rubella, measles, fever, pain and plague (perhaps it could cure COVID-19). Apothecaries across Europe boasted they could sell unicorn horns and elixirs made from ground alicorn. Also for sale were belts made from unicorn leather to protect the wearer from harm.
Royalty was often given alicorns as gifts. Elizabeth I was said to own a unicorn horn and the Throne Chair of Denmark was said to be made from many horns. Commissioned by King Frederick III (1609-70) in 1662, the throne was made by Bendix Grodtschilling (1620-90) to resemble the Biblical Throne of King Solomon described in 1 Kings 10. The throne was used at coronations until 1849 when the Danish monarchy was replaced by a constitutional monarchy. The unicorn horns, however, have since been proved to be narwhal tusks.
As early as 1638, alleged alicorns were being identified as narwhal tusks. Danish physician Ole Worm (1588-1654) was the first to start making this connection with the medium-sized toothed whales that live in the Arctic waters around Greenland, Canada, and Russia.
Ole Worm’s beliefs were studied at length by Sir Thomas Brown (1605-1682) in his Pseudodoxia Epidemica, more commonly known as Vulgar Truths. Brown was a polymath and author of a variety of subjects, including science, religion, medicine and the natural world. Pseudodoxia Epidemica or Enquiries into very many received tenets and commonly presumed truths, to give its full name, challenges the common errors and superstitions of the 17th century. Although Brown tried to be scientifically accurate, he included subtle elements of humour. Of the alleged alicorns, Brown said:
“False alicorn powder, made from the tusks of narwhals or horns of various animals, has been sold in Europe for medicinal purposes as late as 1741. The alicorn was thought to cure many diseases and have the ability to detect poisons, and many physicians would make “cures” and sell them. Cups were made from alicorn for kings and given as a gift; these were usually made of ivory or walrus ivory. Entire horns were very precious in the Middle Ages and were often really the tusks of narwhals.”
Despite, arguments against the existence of unicorns, they have “existed” throughout many cultures and periods. The European unicorn is traditionally believed to have the body of a horse with a pearly white coat and a long, white spiralled horn. In Asia, on the other hand, unicorns are depicted as a scaly, colourful deer-like creature with a flesh coloured horn.
An Asian legend claims the Mongol Emperor Genghis Khan (AD 1162- 1227) was prevented from invading India by a unicorn. The creature is said to have gazed into the leader’s eyes, which Genghis Khan took to be a sign from heaven and ordered his army to retreat.
The Chinese unicorn, also known as the qilin looks less like traditional descriptions of the magical creatures and more like a chimaera. Although it had a single horn, some sources say it had the body of a deer, the head of a lion, and green scales. Other sources claim it had the head of a dragon. According to legend, the qilin first appeared in 2697 BC during the reign of the legendary Yellow Emperor. The Chinese unicorn’s rare appearances were believed to foretell the birth or death of a wise ruler. Rumour says the qilin appeared to the pregnant mother of Confucius (551- 479 BC) in the 6th century BC and once more shortly before his death. Confucius is also said to be the last person to have seen the unicorn.
“A wise man never plays leapfrog with a unicorn.”
– Tibetan proverb
Most of the original myths about unicorns have been forgotten and yet, unicorns have never been more popular than they are today. Social media has spread the unicorn fad across the world, with tips about throwing unicorn parties, making unicorn art and so much more.
Every July, the Festa dell’Unicorno (Unicorn Festival) is held in the Italian town of Vinci (where Leonardo was born). Dressed as fairies, elves or characters from fantasy films, visitors can attend three days of magical shows, concerts, competitions and a medieval market.
The unicorn has been rising in popularity since 2015, helped along with companies, such as Starbucks with their unicorn frappuccino, Kellogg’s Unicorn Fruitloops and Unicorn Snot glitter gel. They also feature in recent films, TV shows and books. It has become a symbol of benevolence and happiness, shunning the harsh realities of today.
Although the unicorn craze belongs to the 21st century, unicorns have featured in famous literature of the past. Shakespeare (1564-1616) mentioned unicorns in his plays Julius Caesar, The Tempest and Timon of Athens. The most famous work of fiction involving the magical creatures is, of course, The Last Unicorn by Peter S. Beagle (b.1939). First published in 1968, the book has sold millions of copies worldwide and has been translated into 20 languages. The story follows a unicorn, who believes she is the last of her kind, on a quest to discover what happened to the rest of her species.

Detail from James Thurber’s original illustration
Another story is The Unicorn in the Garden by James Thurber (1894-1961). The short, humorous tale is about a man who sees a unicorn in the garden but when he tells his wife, she does not believe him. The more the man insists, the more adamant his wife becomes that unicorns do not exist. In the end, the wife has become so obsessed with proving her husband wrong that she is mistaken for the “loony” one.
This, of course, was only a humorous story but would anyone believe you today if you saw a unicorn in your garden? Are unicorns real? Whilst science puts forward evidence to suggest they are not, mystery still abounds, making the answer inconclusive. The stories and legends told throughout time suggest that it is highly unlikely to spot or capture a unicorn, therefore, if they do exist, we may never know.
Whether or not you believe in unicorns, they are fascinating creatures to research. There are so many different beliefs, myths and legends that it is impossible to fully comprehend the legendary creature. Nonetheless, their presence in popular culture is adding a bit of sparkle to the world. So, to paraphrase the Festa dell’Unicorno, enjoy your life, have fun, anything goes, so long as you do not betray the “spirit of the unicorn.”
“The unicorn is noble,
He knows his gentle birth,
He knows that God has chosen him
Above all beasts of earth.”
– German Folk Song
