Myrlyava

Tradition: Sorbian Mythology, German Mythology
Alternative Names: Marawa, Myrlata, Myrlawa, Marava, Myrljata
Category: Demon


The Myth

Myrlyava is an evil demoness from Upper Sorbian folklore who appears as a repulsive, ugly, and perpetually dirty woman.

She was rarely seen, and nobody knew where she came from, where she lived, or what she fed on. Her mysterious nature made her a frightening figure in local folklore.

In Müllrose, in northern Upper Lusatia, people had a saying about a woman who had been working for a long time and was constantly busy with her work. They would say:

“She must be an old Myrlyava.”

The name was therefore used to describe a woman who was regarded as particularly unpleasant or unattractive.

Kulyashi

Tradition: Russian Mythology
Alternative Names: Kulyashi, Kuleshata, Kuleshi
Category: Demon


The Myth

Kulyashi are small water demons from the folklore of the Vologda region of Russia. They live in the water and are said to emerge during Epiphany.

People were afraid of accidentally scooping up a Kulyash when drawing water, and a saying recorded in Vladimir Dal’s dictionary warned that the Kulyashi came out of the water at Epiphany. Because of them, people were careful when going onto or drawing from the water during this time.

In the Russian North, these little water beings were also known as Kuleshi or Kuleshata. They appeared during Svyatki, the Christmas festive period, where they caused trouble and mischief for people. When the festive season came to an end, the creatures disappeared again.

Kulyashi were therefore imagined as small, troublesome supernatural beings that appeared for a short period, disturbed people, and then vanished. They were regarded as a kind of water-dwelling counterpart to the better-known Shulikuny.

Imp

Tradition: English Mythology
Alternative Names: Impe
Category: Demon


The Myth

Imps are small supernatural beings, usually described as lively, troublesome, and mischievous. They are often portrayed as lesser beings, sometimes resembling fairies and sometimes described as small demons or attendants of the Devil.

Imps are known for playing tricks on people. Their mischief can be harmless, but they can also mislead travelers, cause trouble, or otherwise disturb people. They were sometimes believed to seek friendship with humans, using jokes and pranks to gain their attention, although their behavior could just as easily drive people away.

In later folklore, imps became associated with witches and warlocks as familiar spirits. They were believed to serve their masters as companions, spies, or informants. Such familiars could take the form of animals such as black cats, lizards, or toads.

One of the best-known legends concerns the Lincoln Imp. According to a legend from Lincolnshire, the Devil came to Lincoln Cathedral accompanied by two imps. The imps began causing havoc inside the cathedral until an angel appeared and ordered them to stop.

One of the imps attempted to throw a stone at the angel. The angel commanded, “O impious imp, be ye turned to stone,” and the creature was immediately petrified. Its companion escaped, while the unfortunate imp remained as a stone figure inside the cathedral.

Dodomeki

Tradition: Japanese mythology
Alternative Names: 百々目鬼, どどめき
Category: Demon


The Myth

The Dodomeki is a cursed woman with exceptionally long arms covered in hundreds of tiny bird eyes. She was originally a human woman who developed a habit of stealing money. As a consequence of her wicked deeds, hundreds of small bird eyeballs eventually sprout from her arms, transforming her into a monster.

The creature’s appearance is built around a series of Japanese wordplays. Having “long arms” is an expression for someone who has a tendency to steal, so the Dodomeki possesses long arms both figuratively and literally. Copper coins, called dōsen, had holes in their centers and were colloquially called chōmoku, meaning “bird’s eye,” because of their appearance. Thus, a woman who stole copper coins became a monster whose arms were covered in bird eyes.

Money could also be called oashi, literally “feet,” because money comes and goes as though it had feet. The expression ashi ga tsuku means “to catch someone who has committed a crime.” By replacing ashi with chōmoku, which could also refer to money, the expression becomes a pun meaning “covered in bird eyes.” These wordplays were incorporated into Toriyama Sekien’s description of the yokai.

A much older legend tells of Fujiwara no Hidesato, a nobleman who had been granted the position of kokushi of Shimotsuke Province after defeating the rebel Taira no Masakado. While hunting in his newly acquired territory, Hidesato encountered an old man who warned him that an oni had appeared at the horse graveyard at Utsunomiya. Hidesato took his bow and arrows and went to investigate.

He waited at the horse graveyard until nightfall. During the hour of the ox, an enormous demon appeared and began ravenously devouring the carcasses of dead horses. It stood more than ten feet tall, possessed sharp, spiked hair, and had glowing eyes covering its entire body. Hidesato carefully aimed at the brightest eye and fired an arrow directly into it.

The arrow struck the demon, which roared in pain and fled into the woods. Eventually it collapsed at the foot of Mount Myōjin. Yet the wounded demon still possessed tremendous power. Flames erupted from its body, while its mouth split open and released poisonous fumes. The intense heat and toxic air overwhelmed Hidesato, forcing him to abandon the fight and return to his palace.

When Hidesato returned the following day, he found that a large area of ground had been blackened and burned. The demon itself, however, had disappeared.

Four hundred years later, during the Muromachi period, a village had developed on the northern slope of Mount Myōjin. Strange events began occurring there. The head priest of the local temple suffered mysterious injuries, while unexplained fires repeatedly broke out around the temple.

A new head priest, the virtuous Saint Chitoku, was summoned to discover the cause. Chitoku noticed that a young woman frequently visited the temple whenever he preached his sermons. He eventually realized that she was actually the wounded demon from Hidesato’s battle, disguised as a human woman.

After surviving the battle, the demon had retreated into nearby caves to recover. In human form, it repeatedly returned to the place where it had fallen at Mount Myōjin. There it gradually sucked back up the poisonous fumes it had released during the battle and collected the blood it had spilled. Because the village temple had been constructed directly over the old battlefield, the demon began causing fires and attacking the priest in an attempt to drive the people away.

One day, Saint Chitoku confronted the disguised demon. She revealed her true nature as a Dodomeki, but she did not attack him. While repeatedly visiting the temple, she had listened to Chitoku’s powerful sermons, and his teachings had deeply affected her.

The Dodomeki promised that she would never again commit evil. From that time onward, the area around Mount Myōjin became known as Dodomeki.

Udug

Tradition: Sumerian mythology, Iraqi Mythology
Alternative Names: Udug, Udug Hul, Utukku
Category: Demon


The Myth

The Udug is an ambiguous class of demons in ancient Mesopotamian mythology, found in the traditions of Sumer, Akkad, Assyria, and Babylonia. The beings were associated with the underworld, Kur, and were distinct from the dingir, the divine beings of Mesopotamian religion.

The appearance of the Udug is deliberately difficult to define. No certain visual representation has been identified, and ancient descriptions emphasize that the demon is essentially nameless and formless. An Old Babylonian incantation describes the Udug as one who, from the beginning, was never given a name and never appeared in a definite form.

Descriptions of the evil Udug instead focus on its terrifying supernatural characteristics. It is described as having a towering stature, a malignant appearance, a dark or pitch-black shadow, and no light within its body. It hides rather than standing openly, its claws drip with bile, and it leaves poison behind it. Its arms enclose its victim, while its terrifying battle cry is so powerful that it cannot be restrained.

The Udug could attack and afflict human beings, particularly through disease and supernatural possession. Its presence could bring painful illness into the body, while curses, poison, evil forces, and other forms of supernatural harm were attributed to its influence.

The Udug is especially prominent in the Udug Hul incantations, ancient Mesopotamian texts concerned with the exorcism of evil Udug. These texts describe the demon as a source of illness and suffering and place the exorcist in the role of removing the supernatural affliction and restoring the victim.

The word Udug was not always restricted to one precise type of demon. It could be used more broadly for demons as a whole, making the identity of an individual Udug difficult to distinguish from the wider world of Mesopotamian supernatural beings.

The Udug was also associated with other demons, including the Gallû and Lilu. Some traditions additionally connect the name with Hanbi, a mysterious figure described as the father of Pazuzu and associated with evil forces, although little is known about Hanbi himself.

The essential nature of the evil Udug was therefore not a particular physical form but its supernatural presence: darkness, poison, terrifying sound, possession, disease, and the unseen forces that afflicted human beings.

Oni no Nembutsu

Tradition: Japanese mythology
Alternative Names: Oni no Nembutsu, Demon Soliciting Alms
Category: Demon


The Myth

The Oni no Nembutsu is a mischievous demon depicted as an oni dressed in the robes of a Buddhist priest and begging for alms.

The creature belongs to the tradition of the oni, supernatural demons commonly portrayed as frightening but also capable of humorous and mischievous behavior. In the depiction, the demon takes on the appearance and role of a Buddhist religious figure, humorously placing a fearsome supernatural being in the position of a priest who depends upon others for offerings.

The figure was used in the popular tradition of Otsu-e, where mischievous demons could be portrayed in humorous situations and accompanied by moralizing text. The image of the demon dressed as a priest and soliciting alms became one of these humorous supernatural subjects.

Cihuateteo

Tradition: Aztec Mythology, Mexico Mythology
Alternative Names: Cihuateteo, Cihuātēteoh, Cihuātēotl
Category: Demon


The Myth

The Cihuateteo, meaning “Divine Women,” are the spirits of women who died in childbirth. Because childbirth was understood as a struggle equivalent to battle, women who died giving birth were likened to male warriors who had died in violent conflict. A woman in labor was said to capture the spirit of her newborn child in the same way that a warrior captured an enemy in battle.

The Cihuateteo resided in Cihuatlampa, the “place of women,” in the west where the sun sets. Each day, they accompanied the sun toward the west from noon until sunset. Some traditions suggest that they could even carry the sun through the underworld until it rose again. They performed this duty alongside the spirits of male warriors who had died in battle, and this privilege was reserved for these two groups of the dead.

On five particular days of the Aztec calendar—1 Deer, 1 Rain, 1 Monkey, 1 House, and 1 Eagle—the Cihuateteo descended from Cihuatlampa and returned to the earth.

When they appeared on earth, the Cihuateteo were feared as demons of the night. They were particularly associated with crossroads, where roadside shrines were erected to appease them. They were believed to steal children, cause madness and seizures, and tempt men into adultery. Individual Cihuateteo could be associated with the particular calendar day on which they descended.

A woman’s death in childbirth was understood as the result of losing a violent struggle. The gods were believed to have sent the child down to earth, and the woman had to fight and struggle to bring it into the world. If she succeeded, the newborn child was her reward; if she failed, she died and her soul became a Cihuateteotl.

The body of a woman who had died in childbirth was believed to retain extraordinary powers after her soul had departed. Her remains therefore required special protection. An armed group consisting of her widowed husband, his friends, midwives, and elderly women guarded the body against male warriors, who sought parts of it because of their supposed magical power.

The left middle finger and the hair were considered particularly potent. Warriors who obtained these relics could place them on their shields, where they were believed to give them courage and strength while blinding their enemies.

Cihuateteo were depicted as fearsome women with clenched, claw-like fists, bared teeth and gums, and aggressive poses. Their clawed feet could be tucked beneath their skirts, giving them an appearance that was simultaneously seated and ready to attack.

Their bodies often emphasized the physical consequences of childbirth. They were depicted with taut stomachs, exposed breasts, and prominent nipples, emphasizing their unrealized role as mothers who had died before being able to nurse their newborn children.

Their hair was often depicted as long, unkempt, and swirling, sometimes orange in color. Their skirts could be fastened with serpent belts, while some figures from El Zapotal carry staffs bearing heads as trophies and appear covered in flayed skins.

The serpent around the waist may refer to Cihuacoatl, a goddess associated with war, sacrifice, political power, fertility, childbirth, and midwifery. Their unkempt hair was associated with darkness and the earth, while Cihuatlampa itself was a place of darkness. The earth and earth goddesses likewise carried associations with both childbirth and sacrifice, two central aspects of the Cihuateteo.

Alp

Tradition: German Mythology
Alternative Names: Alpe, Alpen, Trud, Mar, Mart, Mahr, Schrat, Walrider
Category: Demon


The Myth

The Alp is a supernatural being from German folklore associated with nighttime oppression, nightmares, illness, and the bewilderment or deception of humans. The word Alp is the German form of the same ancient Germanic word that eventually became English elf.

In older German traditions, the Alp was understood as a nature spirit or nature demon. It was regarded as an eerie and sometimes ferocious being, and was particularly associated with the mare, a supernatural creature that tormented people during sleep.

The Alp was believed to approach sleeping people and oppress them during the night. This association is preserved in the German word Alpdruck, literally “elf-oppression,” meaning a nightmare. The Alp could also be associated with illness, including epilepsy.

Medieval German traditions frequently portray elves as beings capable of deceiving or bewildering people. A recurring expression described a person as being deceived by the elves or by the Alp. Elves could also have a seductive aspect, with medieval poetry describing people as being enchanted or bewitched by them.

By the later medieval period, elves had increasingly acquired a threatening and demonic character. A fourteenth-century German prayer known as the Münchener Nachtsegen invokes protection from the Alp, the Trud, and the Mare, asking these beings not to oppress, pinch, ride, or mount the sleeper.

The Alp was therefore closely connected with other Germanic nightmare spirits. Names such as Trud, Mar, Mart, Mahr, Schrat, and Walrider were used for related forms of supernatural beings, while surrounding European traditions preserved similar figures such as the Drude and the Old Hag.

The Alp was also associated with supernatural influence over human beings beyond sleep. In Northern Germany during the early modern period, elves were described as carrying out the evil wishes of witches. Martin Luther himself believed that his mother had been afflicted in this manner.

German traditions also preserved older associations between elves and other supernatural races. Elves could be connected with dwarfs in German heroic literature, particularly figures whose names or characteristics preserved the older idea of elf power.

Thus, the Alp represents an older Germanic conception of the elf as a potentially dangerous supernatural being: a spirit capable of deception, illness, nocturnal oppression, and supernatural influence over humans.

Black Gentleman

Tradition: Swedish Mythology
Alternative Names: Black Gentleman
Category: Demon


The Myth

The Black Gentleman appears as a fine gentleman dressed entirely in black, arriving in a black coach drawn by two black horses. He comes to claim the wicked Lady of Pintorp and take her away for punishment.

The Lady of Pintorp was a cruel noblewoman who abused the people living on her estate. She imprisoned innocent people in underground dungeons, set vicious dogs upon children and beggars, and brutally punished workers who failed to arrive at the appointed time.

One morning, she ordered a farm-hand who had arrived late to cut down the largest oak on the estate and bring it to the castle courtyard before evening. When the man despaired over the impossible task, he encountered an old man in the woods who told him to sit upon the fallen tree. Invisible bearers then carried the tree rapidly to the castle. The Lady recognized that Erik Gyllenstjerna and Svante Banér were somehow helping the farm-hand, but responded with anger rather than remorse.

At that moment the earth shook, and the Black Gentleman arrived at the castle in his black coach. He descended, bowed to the Lady, and ordered her to prepare herself and follow him.

Knowing who he was, the Lady desperately begged for more time. She first requested three years, then three months, three weeks, and finally three days. The Black Gentleman refused every request and granted her only three minutes to put her affairs in order.

She then asked that her chaplain, chamber-maid, and valet accompany her. The Black Gentleman permitted this, and they entered the coach. The horses immediately carried them away with such supernatural speed that the people at the castle saw only a black streak.

After travelling for some time, they arrived at a magnificent castle. The Black Gentleman led the Lady inside, where she removed her costly clothes and put on a coarse coat and wooden shoes. He then combed her hair three times until she could no longer endure it and danced with her three times until she was exhausted.

After the first dance, the Lady gave her golden ring to her valet, but it burned his finger like fire. After the second, she gave her bunch of keys to her chamber-maid, but the keys seared the girl’s hand like red-hot iron.

After the third dance, a trapdoor suddenly opened in the floor. The Lady disappeared through it amid smoke and flames.

The chaplain looked down into the opening, and a spark rose from the depths and struck him in the eye, leaving him blind in that eye for the remainder of his life.

The Black Gentleman then allowed the three servants to return home, but warned them not to look behind them. They entered the coach and travelled along a broad, even road. Eventually, however, the chamber-maid could no longer resist her curiosity and looked back.

Immediately the coach, horses, and road disappeared. The three travellers found themselves in a wild forest, from which it took them three years to find their way back to Pintorp.
