Aed’s Magical Cow

by

Tradition / Region: Irish Mythology
Alternative names: Magical Cow of Aed
Category: Cow

The Myth

Aed, king of Tara in the sixth century, possessed a magical cow whose presence protected him from harm. He believed that as long as the cow remained near him, its supernatural power would keep him safe, even during battle.

When war came, Aed left the magical cow behind at Tara and rode into battle without it. Separated from his supernatural protector, he faced his enemies without the protection he had trusted.

Aed was killed on the battlefield. The magical cow remained safely at home, unable to protect the king from a distance.

The story tells of a magical cow whose protective power depended upon its presence beside its master.

Kimmo

Tradition / Region: Finnish Mythology
Alternative names: Kimmo
Category: Cow

The Myth

Kimmo is a magical heifer forged by Ilmarinen, the eternal smith and master of metals, during his attempt to create the Sampo. Her horns shine like gold, while the Bear of Heaven and a disc of sunlight mark her forehead.

On the third day of Ilmarinen’s work, after a metal crossbow and a purple-metal skiff had emerged from the furnace and been destroyed, the strange heifer rose from the flames.

Kimmo was wild and impossible to control. She raced through forests, swamps, and meadows, scattering and spilling her milk as she went. No mortal could restrain her, and even Ilmarinen could not tame the creature he had forged.

Realizing that the heifer could not be kept, Ilmarinen cut Kimmo into pieces and threw her back into the furnace. From the magical materials of the forge, the Sampo finally began to take shape, its many-colored lid turning as it produced flour, salt, and gold.

Khalkotauroi

Tradition / Region: Greek Mythology
Alternative names: Colchis Bulls, Bronze Bulls, Tauroi Khalkeoi
Category: Cow

The Myth

The Khalkotauroi are two enormous bulls with bronze hooves and bronze mouths. Flames pour from their mouths, making them dangerous even before they begin to charge.

The bulls were forged by Hephaestus, the divine blacksmith, and given to King Aeetes of Colchis. Aeetes guarded the Golden Fleece and set the creatures as one of the impossible tasks that Jason had to complete.

Aeetes promised Jason the Golden Fleece if he could yoke the two bronze bulls and use them to plough a field. Afterward, Jason was required to sow the freshly ploughed earth with dragon’s teeth.

The heat of the bulls made the task nearly impossible. Their fiery breath could burn anyone who approached them, but Medea, the daughter of Aeetes, had fallen in love with Jason and secretly gave him a magical potion that protected his body from the flames.

Protected by Medea’s potion, Jason approached the Khalkotauroi, endured their fire, yoked the enormous bulls, and forced them to plough the field.

Kettetsu

by

Tradition / Region: Chinese Mythology, Japanese Mythology
Alternative names: Kettetsu, Gnawing Iron
Category: Cow

The Myth

Kettetsu is a strange beast from the southern regions, described with the horns and feet of a water buffalo and a body covered in jet-black fur. Its name means gnawing or eating iron.

The creature feeds on iron and drinks water. According to ancient accounts, its feces were harder than ordinary metal and could be used by people to make sharp weapons.

Descriptions of Kettetsu appear in the Shenyi Jing and later Chinese works such as the Bencao Gangmu. Japanese encyclopedias, including the Wakan Sansai Zue, also recorded the creature from these earlier accounts.

Some traditions placed Kettetsu among a group of iron-eating beasts associated with the baku. The baku itself was sometimes described as a creature capable of eating copper and iron, and in some accounts the two creatures were identified with one another.

In later interpretations, the legend of iron-eating beasts may have developed from ancient descriptions of pandas. An animal originally described as eating bamboo may have been misunderstood as eating the arrows and other objects made from bamboo, copper, and iron, eventually producing the strange tradition of a beast that consumed iron.

Kao

by

Tradition / Region: Indian Mythology
Alternative names: Kao Phaba, Khambana Kao Phaba, Kau Phaapa
Category: Cow

The Myth

Kao was a powerful divine bull that terrorized the people of the Khuman kingdom, killing those who came near the waters where it lived. Its enormous strength and dangerous horns made it impossible for ordinary people to capture.

A wealthy nobleman named Kongyamba wanted the bull captured, but instead of facing it himself, he tricked the brave Khuman warrior Khamba into accepting the task. Kongyamba claimed that the god Thangjing demanded the bull as an offering and told the king that Khamba had promised to capture it. The king then declared that Khamba would be allowed to marry Princess Thoibi if he succeeded.

A great gathering was arranged between the kingdoms, and an enormous enclosure was built for the capture of Kao. On the day of the contest, Khamba faced the charging bull and seized it by the horns. Kao carried him deep into the forest, but Khamba remembered the secret given to him by his sister Khamnu.

She had revealed that Kao had once belonged to their father’s herd. Khamba spoke their father’s name to the bull and showed it a silk rope. At once, the furious beast became calm and gentle.

Khamba began leading Kao back toward the gathering. Kongyamba intercepted them and falsely claimed that he had captured the bull himself. When the dispute could not be settled, Kongyamba was ordered to face Kao inside the enclosure. Terrified, he climbed away from the bull, while Khamba once again confronted the beast and successfully captured it.

The capture of Kao became one of the celebrated episodes of the Khamba Thoibi epic, remembered as Kao Phaba, the taking or capture of the sacred bull.

Kamadhenu

by

Tradition / Region: Indian Mythology
Alternative names: Surabhi, Surabhī, Kamaduh, Kamaduha, Sabala, Kapila
Category: Cow, Deity

The Myth

Kamadhenu is a miraculous white cow who provides whatever is desired and is regarded as the mother of all cows. She is associated with milk, prosperity, fertility, and the sacred rituals of the sages. She is sometimes depicted with the head and breasts of a woman, the wings of a bird, and the tail of a peacock, or with numerous gods represented within her body.

Different Hindu scriptures give different accounts of her origin. In the Mahabharata, Kamadhenu-Surabhi emerged from the churning of the cosmic ocean and was given to the great sages. Brahma commanded her to provide milk and ghee for ritual sacrifices.

In other traditions, Surabhi was born from Daksha, from Brahma, or from the divine act of creation. She became the mother of countless cattle and was associated with Goloka, the realm of the cows, as well as Patala.

Kamadhenu was closely connected with the sages who possessed her. She could provide enormous quantities of food and milk and, when threatened, could even produce warriors to defend her master.

One famous story concerns the sage Vashishtha and his miraculous cow Sabala. King Vishvamitra arrived at the sage’s hermitage with his army, and Vashishtha welcomed them with a great feast produced entirely through Sabala’s supernatural power.

Amazed by the cow’s abilities, Vishvamitra offered the sage thousands of ordinary cattle, elephants, horses, and jewels in exchange for her. Vashishtha refused, explaining that Sabala was essential to his religious duties.

Vishvamitra then attempted to take her by force. Sabala returned to Vashishtha and was ordered to defend him. From her body she produced armies of supernatural warriors, who fought Vishvamitra’s forces and destroyed his army.

Another tradition tells of Kamadhenu living with the sage Jamadagni. King Kartavirya Arjuna attempted to seize the divine cow and her calf. After the conflict led to Jamadagni’s death, his son Parashurama took revenge upon the king and eventually destroyed the Kshatriya warriors twenty-one times.

Kamadhenu is also associated with Nandini, another miraculous cow of plenty who lived with Vashishtha. In some traditions Nandini is Kamadhenu’s daughter, while in others the names Kamadhenu, Surabhi, and Nandini overlap.

When Kamadhenu’s son, a bullock, was cruelly overworked and beaten by a farmer, she wept over his suffering. Her tears were seen by Indra, who was moved by her grief and sent rain to stop the torment.

Kamadhenu remains a divine source of cattle, milk, prosperity, and protection, while her miraculous ability to provide nourishment and warriors makes her one of the most powerful supernatural cows in Hindu mythology.

Guallipén

by

Tradition / Region: Argentine Mythology, Chilean Mythology
Alternative names: Waillepeñ, Huallepén, Huallepenyú, Huaillepenyí, Wayfü
Category: Cow

The Myth

The Guallipén is a strange animal with the body of a sheep and the head of a calf. It has four crooked legs, poor-looking wool, and makes a bleating sound like a sheep.

The Guallipén lives in low, humid places near bodies of water, especially swamps known in Mapuche tradition as münoko. It moves by pushing itself forward with its front legs while dragging its hind legs behind it.

On land, the Guallipén is said to be harmless, but in the water it becomes dangerous and attacks fiercely. When it encounters livestock, it can mate with them and cause their offspring to be born with deformities.

A pregnant woman who sees a Guallipén in a perimontu, a supernatural vision, receives a terrible omen concerning her unborn child. Depending on the tradition, the child may be born with deformed or atrophied limbs, rickets, an intellectual disability, or without bones.

Because of this danger, sexual relations near wetlands were traditionally regarded as taboo. A child believed to have been conceived after such an encounter could be described as a wallipeñ kulliñ, an incarnation of the Guallipén.

Hiromushime

by

Tradition / Region: Japanese Mythology
Alternative names: Tanaka no Mahito Hiromushime, Hiromushi-onna
Category: Cow

The Myth

Hiromushime was a wealthy woman from Sanuki Province who possessed cattle, horses, slaves, rice, money, and farmland. She was extremely miserly and exploited those around her through dishonest trade and harsh lending practices.

When selling sake, she diluted it with water to increase her profits. When lending rice and other goods, she used small measures and scales, but when collecting repayment she used larger ones. Some of her debtors were forced to abandon their homes and flee to other provinces.

In 776, Hiromushime became seriously ill. Shortly before her death, she told her husband and sons about a dream in which she had been brought before King Yama. She was shown three offenses: taking things belonging to temples and monks without repayment, adulterating sake for profit, and using different measures when lending and collecting debts.

Hiromushime died that same day. Her family decided to pray for her rather than cremate her body, gathering monks and ascetics to perform religious rites for nine days.

On the seventh day, Hiromushime suddenly returned to life and opened her coffin. Her body had been horribly transformed. Her upper body had become that of a cow, a horn had grown from her forehead, and her hands had become hooves. Only the lower half of her body retained its human form.

She no longer wanted ordinary food and instead ate grass, chewing it repeatedly and spitting it out before eating it again. She also lived without clothing and showed no concern for where she slept or defecated.

News of the transformation spread, and crowds gathered from surrounding areas to see her. Her family was filled with shame and grief and began making religious vows to atone for her wrongdoing.

They donated large amounts of property to temples, including seventy cows, thirty horses, rice fields, and thousands of bundles of rice. They also forgave all the debts owed by the people from whom Hiromushime had previously demanded repayment.

Five days later, while the provincial authorities were preparing their report about the strange event, Hiromushime died for a second time.

Gyūkan

by

Tradition / Region: Japanese Mythology
Alternative names: Kiukan
Category: Cow

The Myth

Gyūkan is a strange disease-causing entity believed to develop inside the human body. It is depicted as a cow with black horns and was understood as a mass that forms within the lungs.

According to the Shinmonsho, when the Gyūkan develops, it causes severe illness. When the afflicted person attempts to eat, the condition can trigger a sudden seizure and loss of consciousness.

The Gyūkan was considered difficult to treat once it had fully developed, although the Shinmonsho describes various acupuncture treatments that could be used against it. The creature is illustrated alongside other disease-causing beings in the sixteenth-century medical manual.
