Lou Carcolh

Tradition: French Mythology
Alternative Names: Carcolh, The Carcolh
Category: Dragon, Mollusc


The Myth

Lou Carcolh is a gigantic, slimy creature resembling a monstrous serpent combined with a snail. It has a huge shell upon its back and long, hairy tentacles capable of reaching far beyond its body. The creature is said to dwell in a cavern beneath Hastingues in the Landes of southwestern France.

The Carcolh’s approach could be detected before the beast itself appeared. A trail of thick slime would sometimes be seen stretching through the landscape, announcing that the enormous creature was drawing near. Its long tentacles were its most dangerous weapon. Hidden within or near its cavern, the Carcolh could stretch them out over a great distance, seize an unsuspecting person, and drag them back into its lair without ever revealing itself.

Hastingues itself became closely associated with the monster. The town sits upon a rounded hill, giving it the nickname “the Carcolh,” while local men were said to warn young and beautiful women with the ominous words that the Carcolh would catch them.

Lao Jian

Tradition: Chinese mythology
Alternative Names: Old Jian, Lao Jian, Jian Shi
Category: Dragon


The Myth

Lao Jian is a poisonous dragon of ancient Chinese mythology, a dangerous creature associated with floods and destructive waters. His presence could cause severe water damage, and his power was great enough that he had to be subdued by Li Bing, the governor and general of Shu.

During the Qin Dynasty, Li Bing confronted the poisonous dragon Jian Shi and subdued it, binding it with chains and locking it on the river. Once the dragon had been restrained, the flooding ceased.

The identity of Jian is connected with Nie Zi, a wicked dragon from the legend of Wang Niang Tan. When Nie Zi transformed himself into a dragon, his mother managed to hold onto one of his feet, preventing that foot from undergoing the transformation. He therefore remained lame, and this peculiar deformity gave rise to the name Jian.

The name is further connected with Nie Zi’s surname, Nie, which is said to echo the name of the dragon. Thus Lao Jian is remembered as the poisonous, crippled dragon whose watery power was finally restrained by Li Bing.

Hydra of Lerna

Tradition: Greek mythology
Alternative Names: Lernaean Hydra, Hydra
Category: Dragon


The Myth

The Hydra of Lerna was a monstrous, many-headed serpent that dwelt in the waters and marshes of Lerna in the Argolid. It possessed poisonous breath and blood so deadly that even its scent could kill. Its lair was a deep cave near the spring of Amymone, from which the creature emerged to terrorize the surrounding villages. The exact number of its heads varied in ancient accounts, with different traditions giving it six, nine, fifty, or simply many heads.

The Hydra was said to be the offspring of Typhon and Echidna. Its most terrible power was the ability to regenerate its severed heads. When Heracles cut off one of them, two more could grow from the wound, making the creature seemingly impossible to destroy. In some traditions it possessed a single immortal head among its many mortal ones.

The Hydra was raised by Hera for the purpose of destroying Heracles. As the second of his Twelve Labours, Heracles was commanded by Eurystheus, king of Tiryns, to slay the monster. He came to the marshes of Lerna and covered his mouth and nose against the creature’s poisonous fumes. He then drove it from its lair by shooting flaming arrows into the cave.

Heracles attacked the Hydra with his weapon, cutting off its heads one after another. But each severed head was replaced by new ones, and the monster could not be defeated while its immortal head remained. Realizing that strength alone would not overcome it, Heracles called upon his nephew Iolaus for help.

Iolaus took a burning firebrand and, whenever Heracles severed a head, cauterized the exposed neck before another could grow. Thus the regenerative power of the Hydra was finally overcome. Hera tried to save the monster by sending a gigantic crab to distract Heracles, but he crushed it beneath his foot.

At last Heracles severed the Hydra’s immortal head with a golden sword given to him by Athena. The head remained alive and writhed even after it had been cut away, so Heracles buried it beneath a great rock beside the sacred road between Lerna and Elaius. He then dipped his arrows into the Hydra’s poisonous blood, giving them a deadly venom that would later bring death to other enemies.

The Hydra’s poison continued to haunt the stories of Heracles. He used his poisoned arrows against the Stymphalian Birds, Geryon, Ladon, and the centaur Nessus. The poisoned arrow that struck Nessus ultimately led to the death of Heracles himself, as the centaur’s tainted blood was later used upon the Tunic of Nessus. The poison was also said to have contaminated the river Anigrus in Elis, whose foul-smelling waters were believed to have become poisonous because of the Hydra’s venom.

After Heracles killed the creature, Hera placed the Hydra among the stars as the constellation Hydra. The crab she had sent to aid it was likewise raised into the heavens as Cancer.

The Hydra’s regenerative heads became a symbol of an enemy or problem that only grows more difficult when attacked carelessly. The ancient Greeks even used the expression “cutting off a hydra” for a task that seemed endlessly futile, since destroying one part only caused more to appear.

Ladon

Tradition: Greek mythology
Alternative Names: Ladon, Dragon of the Hesperides
Category: Dragon


The Myth

Ladon was a great serpent-like dragon that coiled around the sacred tree in the Garden of the Hesperides, guarding its golden apples. In some traditions he was said to possess a hundred heads, each capable of speaking with a different voice.

Ladon was one of the final offspring of Phorcys and Ceto according to Hesiod, while other traditions made him the child of Typhon and Echidna, Typhon alone, or even said that he sprang from the earth. He was also described in one tradition as the brother of the Nemean Lion.

During the eleventh labour of Heracles, the hero was commanded to obtain the golden apples. He came to the Garden of the Hesperides and killed Ladon with his bow and arrows before taking the precious apples.

The dragon’s death was not the end of the tale. The following day, Jason and the Argonauts passed through the region on their return from Colchis. They heard the lament of Aegle, one of the Hesperides, and saw Ladon’s body still twitching after his death.

There was also another telling in which Ladon was never killed. Instead, Heracles persuaded the Titan Atlas to retrieve the golden apples for him while Heracles took Atlas’s place and held up the heavens.

Ladon was later associated with the constellation Draco. According to the tradition attributed to Hyginus, Zeus placed the slain dragon among the stars, where it remained as the celestial image of the guardian of the golden apples.

La Guita Xica

Tradition: Catalan folklore, Spanish Mythology
Alternative Names: Guita Boja, La Guita Xica, Mulaguita, La Mulassa, Mula Fera, Mula Guita
Category: Dragon, Horse


The Myth

La Guita Xica is a strange dragon with the body of a mule and the features of a dragon. She has a green, horse-like body, a very long neck, and sharp fangs. Her long neck gives her an uncanny resemblance to a great serpent rising above the crowd.

Originally, La Guita Xica was regarded as a threatening demonic creature. Her nature was connected to the mule, an animal deeply familiar in the Catalan mountains but also notorious for its stubborn and unruly temperament. This wildness became part of the creature herself, making her a dangerous and unpredictable presence.

Over time, however, La Guita Xica changed from a frightening monster into a protective spirit. She became associated with the people of Catalonia and with the Eucharistic celebrations of the Patum de Berga.

During the festivals, enormous representations of La Guita Xica are brought into the town squares. The great dragon-mule moves among the celebrations and spits fireworks, transforming the once-feared creature into a spectacular guardian of the festivities.

Her many names preserve the changing image of the creature: Mulassa, Mulaguita, Guita Boja, Mula Fera, Mula Guita, and finally La Guita Xica. What began as a monstrous mule-dragon became a beloved protective figure within Catalan tradition.

Laidly Worm of Spindleston Heugh

Tradition: English Mythology
Alternative Names: The Laidly Worm of Bamborough, Laidly Worm
Category: Dragon


The Myth

The Laidly Worm is a monstrous dragon into which Princess Margaret of Bamburgh is transformed. The creature is a fearsome worm, dwelling among the rocks and caves of Spindleston Heugh, where it becomes a terror to the surrounding land.

In the Kingdom of Northumbria, the kind king of Bamburgh loses his wife and later takes a beautiful but cruel witch as his queen. The new queen becomes jealous of the king’s daughter, Princess Margaret, whose beauty she resents. With the king’s son, Childe Wynd, away across the sea, the witch sees her opportunity to rid herself of the princess.

She casts a terrible enchantment upon Margaret, transforming her into the Laidly Worm. The curse declares that she shall remain a dragon until Childe Wynd, the king’s own son, comes to the Heugh and kisses her three times. Until then, she is doomed to remain in her monstrous form.

The dragon becomes a fearsome presence around Spindleston Heugh and must be appeased with food. In Joseph Jacobs’ telling, seven cows are set aside for the creature each day. News of the terrible worm eventually reaches Childe Wynd, who returns despite the efforts of his stepmother to prevent him from reaching his sister.

When Childe Wynd finally comes before the Laidly Worm, he does not attack the monster. Instead, he kisses the dragon three times. The enchantment is broken, and the monstrous worm is restored to Princess Margaret in her human form.

The wicked queen is punished for her sorcery, being transformed into a toad, while Childe Wynd becomes king. The tale thus ends with the princess restored, the enchantment broken, and the witch who caused it stripped of her human form.

Spindleston Heugh itself became bound to the legend. The great stone column known as the Spindlestone, or Bridle Rock, is said to be the place where Childe Wynd threw his horse’s bridle before confronting the worm. The surrounding landscape was traditionally associated with the dragon’s dwelling, including a cave and a stone trough where the Laidly Worm was said to have lived and fed.

Kulshedra

Tradition: Albanian mythology
Alternative Names: Kuçedra, Kulshedër, Kulshedra
Category: Dragon


The Myth

The Kulshedra is a gigantic female dragon, usually imagined as a monstrous multi-headed serpent covered in woolly red hair. She has a long tail, seven to twelve heads, and enormous pendulous breasts that hang down to the ground. She can spit fire, and her milk and urine are poisonous. She may also appear in the form of a woman, or as a female lizard, turtle, frog, or salamander.

The Kulshedra is a creature of water, storms, fire, and the earth beneath the world. She brings drought, torrents, tempests, floods, water shortages, earthquakes, and other disasters upon humanity. When her anger becomes dangerous, people may offer her human sacrifices in an attempt to persuade her to hold back the destruction.

In the southern traditions, the Kulshedra is so enormous that she surrounds the entire world. Should she ever manage to bring her mouth around to her own tail, the world itself would be destroyed. In northern traditions she can seize or possess the sun and moon, and people try to frighten her away by firing weapons into the sky, making great noise with metal objects, or ringing church bells.

The Kulshedra is opposed by the Drangue, a divine, winged hero who protects mankind. Their battles shake the natural world: thunder and violent storms erupt as the two enemies clash, while earthquakes, cyclones, and other catastrophes may accompany their struggles. Other celestial heroes can also fight her, including the Daughter of the Moon and the Sun, who uses her powers of light to protect those she loves, and Zjermi, the Fire, who is born with the sun marked upon his forehead.

The Kulshedra does not always reveal herself as a monster. She can disguise herself as an ordinary woman, hiding her true nature until the moment comes to strike. Her presence can even bring prosperity to the village where she dwells. She draws food and other nourishment toward herself with her breath, causing her own village to flourish while neighbouring villages become poor. Her children, the Shlligë, are themselves storm-bringing creatures.

The Kulshedra begins its existence as a Bolla, a demonic serpent with aquatic and chthonic qualities. The Bolla keeps its eyes closed throughout the year, opening them on Saint George’s Day, when it gazes upon the world and devours any human it sees. If it survives for the required number of years without being discovered by a human, it undergoes further transformations, passing through forms known as the Bollar and Errshaja before eventually becoming a Kulshedra.

Brave villagers sometimes seek out these serpents and kill them while they are sleeping, before they can grow into the far more dangerous Kulshedra.

In Albanian folklore, the struggle between the Kulshedra and the Drangue is the great battle between darkness and light, destruction and protection. When the dragon rises, storms and disasters threaten the world; when the celestial hero defeats her, the danger is driven back and the world is restored.

Kuzuryū

Tradition: Japanese mythology
Alternative Names: Nine-Headed Dragon, Kuzuryū Gongen, Kuzuryū Ōkami,
Category: Dragon


The Myth

The Nine-Headed Dragon, or Kuzuryū, is a great dragon with nine heads and a single tail. It is especially associated with water, mountains, rain, and sacred places throughout Japan.

At Mount Togakushi in Shinshu, a great dragon with nine heads and one tail was said to dwell when a scholar-ascetic arrived there in search of a place where Buddhism could flourish. The dragon, also described as an oni, had become a harmful presence in the mountain. Through the power and merit of the Lotus Sutra, the ascetic overcame its harmful influence and caused the dragon to repent.

Kuzuryū then vowed to protect Mount Togakushi and urged the ascetic to establish a great temple there. Afterward, the dragon concealed itself by sealing the treasure cave with a huge rock. The cave was the place where the vajra thrown from Mount Iizuna had landed. This act was said to give Mount Togakushi its name, while the ascetic established Kenkōji Temple, later associated with Togakushi Shrine, where Kuzuryū Gongen was enshrined.

Kuzuryū became especially revered as a water god. People prayed to it for rain, and a particular ritual involved taking water from Taneike Pond to Togakushi Shrine and having prayers for rain performed over it. The water was then carried back without allowing it to touch the ground and sprinkled over the rice fields, after which rain was expected to fall.

Kuzuryū was also believed to have a fondness for pears. Offerings of pears were traditionally made to the dragon to relieve toothaches. People suffering from tooth pain could write their names and the location of the pain on pears, pray toward Mount Togakushi from a distance, and then set the pears afloat in a river.

Another legend connects the Nine-Headed Dragon directly with the creation of Mount Togakushi. When Amaterasu Ōmikami hid inside the Heavenly Rock Cave, Tajikarao no Mikoto attempted to open it. He pulled with such force that the rock was thrown down into the lower world, where it became Mount Togakushi. The Nine-Headed Dragon God appeared in response to the sound of the falling rock, and the Kuzuryū of Togakushi was regarded as a temporary manifestation of this Dragon God.

Nine-headed dragons appear in other Japanese legends as well. At Lake Ashi in Hakone, a poisonous dragon once rampaged through the waters until the monk Manmaki subdued it, after which the dragon became a god and was enshrined as Kuzuryū Daimyōjin. In Fukui, a nine-headed dragon is said to have swum along the Kuzuryū River as though carrying the floating statue of Hakusan Gongen. On Mount Onikiri in Chiba, another nine-headed dragon was defeated by Yamato Takeru and subsequently enshrined at Jinnoji Temple.

In Tadami, Fukushima, the name of the Kuguryū district is connected to another legend in which a nine-headed dragon rose from a swamp and ascended into heaven. Across these traditions, the Nine-Headed Dragon appears as a powerful supernatural being of water and mountains, sometimes dangerous and destructive, but capable of repentance and becoming a divine protector.

Kurikara Ryūō

Tradition: Japanese mythology
Alternative Names: Kurikara Ryūō, Kurikara Dairyu, Kurikara Dragon King, Kurikara Fudō Myōō, Kurikara Myōō, Karaka
Category: Dragon


The Myth

Kurikara Ryūō appears as a gigantic black dragon wrapped in flames, coiling around an upright sacred sword, usually a three-pronged sword, and attempting to swallow it from the tip. In other depictions his body is golden, with a jade horn growing from his forehead, while flames of samadhi surround his coiling body. His four legs are associated with four other Myōō: Gosanze Myōō, Gundari Myōō, Enmaten Myōō, and Kongōyasha Myōō.

Kurikara Ryūō is regarded as a manifestation of Fudō Myōō. His most famous legend tells of Fudō Myōō’s battle against heretics in Maheshura’s City, in the highest realm of the Form Realm. Fudō transformed himself into a sword of wisdom fire, while Chitatsu, leader of ninety-five kinds of heretics, likewise transformed into a sword of wisdom fire.

Fudō’s sword of wisdom fire then transformed into the enormous Kurikara Dragon. The dragon coiled itself around the heretics’ swords and attempted to swallow them. When it opened its mouth and breathed, the sound was so tremendous that it was compared to twenty billion thunderclaps roaring at once. The heretics heard the terrifying sound and abandoned their evil attachments.

The Kurikara Great Dragon was said to be 100,000 yojanas tall. His sacred dharani possessed immense magical power: those who recited it were believed to be able to remove misfortune and subdue demons. Praying to Kurikara Ryūō or chanting his name was likewise believed to dispel fear and evil obstacles and secure a peaceful afterlife.

Kurikara Ryūō was also believed to possess the power to drive away illness and disease and to summon clouds and control rainfall. His image was therefore used in prayers for protection from sickness and for rain.

Another legend tells of a demon king who once lived in the place that later became Kurikara Village and tormented its people. The monk Zenmui enshrined Kurikara Fudō there, and the deity subdued the demon king. The village and the mountain pass subsequently came to be known as Kurikara.

The legend further tells that Kurikara Fudō appeared from Kurikara Fudō Pond, where many miraculous events were said to have occurred. The deity thus became both the dragon coiled around the sword of wisdom and the divine protector who subdued demons, overcame evil, drove away disease, and brought protection to those who called upon him.

Lagar

Tradition: Japanese mythology
Alternative Names: Lagaru, Lagarto, Lakarta
Category: Dragon, Crocodile


The Myth

Lagar was a gigantic reptilian sea monster, described as having a crocodile-like body, four legs, a long slender tail, and a body completely covered in extraordinarily hard scales. Its claws were sharp and its teeth were like saws. The scales were said to be so hard that spears, swords, arrows, and even poisoned arrows could not penetrate them. Its belly, however, contained a soft and vulnerable spot.

Lagar could reach around twenty feet in length. It lived in the sea, where it hunted fish, but when it came ashore it attacked and devoured animals and people. Despite its terrifying strength, it was slow-moving, allowing fish to escape it and people to attempt to flee. It did not eat small fish, instead swimming behind them so that they would not become prey to other creatures.

The monster was said to lay eggs, each roughly the size of a goose egg. When Lagar came ashore, it spat saliva onto the ground. Anyone who stepped in the saliva could slip and fall, leaving them helpless before the beast, which would immediately attack and devour them. It was also said to pursue anyone who tried to flee from it, although the strange creature would itself run away if a person chased after it.

Lagar had several natural enemies. One kind of fish was said to attack the soft underside of its body and stab it to death. A smaller creature could cover itself in mud, leap directly into Lagar’s mouth, and devour its internal organs from within. The monster was also unable to approach places where a plant called Zatsuburaran had been planted.

A terrifying tale from the seas of Ezo tells of another creature believed to be the same monster. This beast was around ten feet long, with sharp claws, saw-like teeth, a crocodile-like body, and scales resembling those of a shark. Even poisoned arrows could not pierce its body. It was powerful enough to kill and devour enormous fish and would sometimes come ashore to eat animals.

Because the creature moved slowly, people attempted to capture it, though many were killed in the process. Eventually they discovered the vulnerable spot beneath its belly. By firing poisoned arrows into this soft place, they managed to kill three of the monsters. After those three were slain, no similar creature was said to appear again.

There was an even more frightening account of Lagar. It was said to imitate the sound of a human crying, luring people toward it from a distance. Once they came close, it would bite and devour them. Its saliva could make people slip and fall, while its eyes, dull and lifeless beneath the water, were said to shine brightly when it came ashore.

Lagar was also said to stop eating entirely during winter and, strangely, to possess no tongue inside its mouth.
