Aspidochelone

Tradition: Greek Mythology
Alternative Names: Asp-Turtle, Fastitocalon, Zaratan, Jasconius
Category: Turtle

The Myth

The Aspidochelone is a gigantic sea creature described in the Physiologus and medieval bestiaries as either a whale or a vast sea turtle. Its enormous back resembles a rocky island, complete with sand and vegetation, making it difficult for sailors to distinguish it from land.

When sailors mistake the creature for an island, they anchor their ships beside it and climb onto its back to rest or prepare food. The heat from their fires awakens the creature, which dives beneath the waves and drags the sailors and their ships into the depths. The Aspidochelone is also said to emit a sweet smell that attracts fish, which it then devours.

The legend appears in the Physiologus, a Christian text dating to around the second century AD, and in later medieval bestiaries. Its story served as a moral allegory: just as the creature deceives sailors with its island-like appearance, Satan deceives people with false promises before leading them to destruction.

Lagopus

by

Tradition: Greek Mythology, Roman Mythology, Italian Mythology
Alternative Names: Hare-Footed Ptarmigan, Lagopus
Category: Rabbit

The Myth

According to Pliny the Elder, the lagopus, whose name means “hare-foot,” is a bird about the size of a pigeon, entirely white, with feet covered in hair resembling those of a hare. Its flesh is considered delicious, but the bird cannot be tamed or kept outside its native habitat. Pliny also states that it putrefies rapidly after being killed.

Thomas de Cantimpré misinterpreted Pliny’s reference to the bird’s native land, concluding instead that the lagopus does not feed in the open air. From this, he reasoned that it must carry its food into a cave to eat. Albertus Magnus extended this interpretation further, deducing that the bird could not fly well.

Although the original description mentions only hare-like feet, later depictions often give the lagopus a hare’s head as well. It is frequently illustrated standing in front of a cave, reflecting the medieval interpretations of its feeding habits.

Calydonian Boar

by

Tradition: Greek Mythology
Alternative Names: Aetolian Boar, Calydonian Wild Boar
Category: Pig

The Myth

The Calydonian Boar was a monstrous wild boar sent by the goddess Artemis to ravage the countryside around Calydon in Aetolia. King Oeneus had neglected to include Artemis in his annual harvest sacrifices to the gods, angering the goddess. In retaliation, she unleashed an enormous and ferocious beast upon his kingdom, where it destroyed vineyards and crops, devastated the countryside, and forced the inhabitants to seek refuge behind the city’s walls.

The boar was described as an extraordinarily terrifying creature, with bloodshot eyes that burned like fire, a thick neck covered in stiff, spike-like bristles, enormous tusks, and jaws that produced deafening roars. According to Ovid’s Metamorphoses, its breath scorched the green fields as it rampaged through the land. Strabo records a tradition identifying the beast as the offspring of the Crommyonian Sow, another monstrous pig defeated by the hero Theseus.

To save Calydon, Meleager led a company of Greece’s greatest heroes on a hunt to kill the beast. The hunters included numerous legendary figures, and in most accounts the hunt also featured the huntress Atalanta, who was the first to wound the boar with an arrow. After the animal was killed, Meleager awarded its hide to Atalanta, provoking a dispute among the hunters that contributed to the tragedy surrounding the expedition.

The Calydonian Boar Hunt became one of the major heroic adventures of Greek mythology, bringing together heroes whose stories were connected to other famous events, including the voyage of the Argonauts and the Trojan War generation. The hunt was frequently depicted in ancient Greek and Roman art. Although Homer and Hesiod were familiar with the legend, no complete surviving account from either poet remains; important versions are preserved in fragments attributed to Stesichorus, the Bibliotheca, and Ovid’s Metamorphoses.

Erymanthian Boar

by

Tradition: Greek Mythology
Alternative Names: Erymanthian Wild Boar, Erymanthian Boar (ὁ Ἐρυμάνθιος κάπρος), Aper Erymanthius
Category: Pig

The Myth

The Erymanthian Boar was a gigantic, savage beast in Greek mythology, described as shaggy, untamable, enormously heavy, and foaming at the jaws. It inhabited the mountainous wilderness of Arcadia, particularly the wooded heights of Mount Erymanthus and the surrounding valleys and marshes. From its forest refuge, the boar would descend to ravage the groves of Arcadia and devastate the countryside around Psophis, threatening farmers and their lands. Its habitat was also associated with Mount Erymanthus, a region connected with Artemis, the goddess of the hunt and wild animals.

The capture of the Erymanthian Boar was the fourth labour of Heracles, who was ordered by King Eurystheus to bring the animal back alive to Mycenae. Heracles pursued the beast through the wilderness, driving it from its hiding place with loud shouts before forcing it into deep snow. Exhausted and trapped by the snow, the boar could no longer escape. Heracles bound it in chains and carried it on his shoulder to Mycenae, completing his task despite the animal’s size and strength. When Eurystheus saw the hero approaching with the enormous boar, he was so terrified that he hid inside a bronze vessel.

According to one tradition, the inhabitants of Cumae claimed that the tusks preserved in the sanctuary of Apollo there belonged to the Erymanthian Boar, although this identification was regarded as highly improbable. The creature also reflects the danger that wild boars represented in ancient Greek traditions. When Artemis was angered, she could send a devastating boar to ravage a region, as in the story of Meleager and the Calydonian Boar. The Erymanthian Boar thus embodied the destructive power of the untamed wilderness and the challenge faced by heroes who sought to master it.

Kranokolaptes

by

Tradition: Greek Mythology, Egyptian Mythology
Alternative Names: Head Striker
Category: Insect

The Myth

The Kranokolaptes is a deadly insect from ancient accounts of Egypt, described as resembling a moth with four soft, downy wings covered in a felt-like texture. Its wings leave behind a trail of ashy dust, while its body is thick and heavy, with a fat abdomen and a hard head that constantly nods. Beneath its head lies a deadly stinger, which the creature uses to attack humans.

The Kranokolaptes strikes at the head and neck, and its sting is said to cause instant death. Victims can survive only if treated with the creature’s own antidote: a Kranokolaptes drowned in oil. The insect is associated with the persea tree, where it develops, possibly a species of Mimusops.

Although the ancient writer Nicander classified the Kranokolaptes among spiders, its description bears little resemblance to an arachnid. Another ancient account describes it as green, though this may have resulted from a misreading of Nicander’s original description. Its deadly bite may explain why it was grouped alongside dangerous spiders despite its moth-like appearance.

Modern interpretations have suggested that the Kranokolaptes legend may have been inspired by large hawkmoths, whose thick bodies and prominent mouthparts resemble aspects of the creature. The vampire moth Calyptra thalictri offers another possible comparison because it can pierce skin to drink blood and rocks its head as it does so. However, its bite causes swelling and irritation rather than the instantaneous death attributed to the mythical Kranokolaptes.

Gold-Digging Ants

by

Tradition: Greek Mythology, Indian Mythology
Alternative Names: Indian Gold-Digging Ants; Myrmekes
Category: Insect

The Myth

Gold-digging ants are enormous, powerful creatures said to inhabit gold-rich deserts in distant lands. Herodotus placed them in the sandy deserts of the Dards in India, within the Persian Empire, while later accounts, including the Ortus Sanitatis, relocated them to Ethiopia. Despite the differences in their supposed homeland, the stories describe creatures that dig up precious gold and fiercely defend their territory.

These creatures are smaller than dogs but larger than foxes. Pliny compared their size to that of an Ethiopian wolf and described their colour as resembling a cat. Skins attributed to the ants and presented before Alexander the Great were said to resemble panther skins. In the Ortus Sanitatis, however, the gold-digging ant looks unlike any ordinary ant or familiar animal. It has a rounded, bird-like head and four legs equipped with long talons. Whatever their appearance, the creatures are described as exceptionally swift, strong, and dangerous.

Gold-digging ants excavate their nests in areas rich in gold dust. As they dig underground, they bring sand containing the precious metal to the surface. This makes their nests tempting targets for treasure seekers, but the ants guard their riches aggressively. Anyone who attempts to steal their gold risks being caught and torn apart by the creatures.

Treasure hunters use camel caravans to raid the nests during hot summer mornings, when the ants remain underground. They rapidly collect the gold-bearing sand and load it into bags before the creatures detect their presence. However, the ants soon catch the scent of the intruders and rush to the surface. The camels must have a substantial head start, because the pursuing creatures are said to be fast enough to catch them and dismember them if they fail to escape.

The true identity of the gold-digging ants remains uncertain. Various explanations have suggested that they were not insects at all, but mammals whose digging habits and ferocity inspired the stories. Proposed candidates include hyenas, whose Persian name may have resembled the Greek word for ant, and Siberian foxes, which are known for digging and fierce behaviour. Another theory identifies the creatures as Himalayan marmots, whose extensive burrowing could bring gold-bearing material to the surface. According to this explanation, the Greek word murmex, meaning ant, may have contributed to confusion between ants and marmots.

Indus Worm

by

Tradition: Greek Mythology, Indian Mythology
Alternative Names: Worms of the Indus
Category: Insect

The Myth

The Indus worm is a gigantic aquatic predator said to inhabit the Indus River in India. It resembles the worms found in figs or rotten wood, but grows to an enormous size, measuring around seven cubits, or more than three metres, in length. Its body is so thick that a ten-year-old boy could barely wrap his arms around it, and its skin is approximately two fingers thick. Its most terrifying features are two enormous, square teeth, one in its upper jaw and one in its lower jaw, each measuring about eighteen inches long.

During the day, the worms remain submerged in the river, wallowing in the mud. At night, they emerge to hunt animals as large as cows and camels. They seize their prey, drag it into the water, and devour it at leisure, crushing flesh, bone, and even stone with their immense teeth. Only the animal’s paunch is left uneaten. There are also accounts of hungry worms attacking drinking camels and oxen in broad daylight, grabbing them by the nose and dragging them beneath the water.

Despite their terrifying nature, the Indus worms are prized for the oil contained within their bodies. This oil is extraordinarily flammable and can consume wood and animals alike. Fires started with it are said to be almost impossible to extinguish, requiring large quantities of clay and rubbish to smother the flames. Because the oil is so rare and valuable, only the king of India is permitted to possess it, and it is stored in clay vessels for use as a devastating weapon during sieges.

Obtaining the oil requires a dangerous expedition. Hunters capture a worm using a hook baited with a lamb or kid chained to it. Once the creature is hauled ashore, it is killed with javelins, swords, and clubs. The carcass is then suspended for thirty days, with vessels placed beneath it to collect the oil that slowly drips from its body. A single worm yields approximately five pints of oil before its remains are discarded and the precious substance is sent to the king.

The Indus worm has sometimes been compared to the Odontotyrannus, another legendary creature associated with India. Both are described as dangerous predators connected with aquatic environments, although their other characteristics differ.

Ichneumon

by

Tradition: Greek Mythology, Egyptian Mythology
Alternative Names: Echinemon, Pharaoh’s Rat, Egyptian Mongoose
Category: Marten

The Myth

The Ichneumon is a swift, ferret-like animal with a slender body and an elongated head. In ancient accounts, it is renowned as a deadly enemy of dragons, crocodiles, and venomous serpents, particularly the asp. When preparing to fight, the creature covers its body with mud and dries it in the sun, building up a protective coating like a suit of armour. It is said to close its nostrils with its tail before attacking a dragon, then use its speed and agility to overcome its much more dangerous opponent.

The Ichneumon’s most famous enemies are the crocodile and the asp. According to ancient traditions, it destroys asp eggs and attacks the serpents themselves, using its mud-covered body for protection against their venomous bites. It seizes its opponents by the head, throat, or tail, and some accounts describe it dragging serpents into the water to kill them. Against crocodiles, the Ichneumon supposedly waits until one is basking with its jaws open, slips inside its mouth, and devours its internal organs. These extraordinary tales made the creature a symbol of cunning and courage, capable of defeating animals far larger and more dangerous than itself.

Nemean Lion

by

Tradition: Greek Mythology
Alternative Names: Lion of Nemea, Leo Nemeaeus
Category: Lion

The Myth

The Nemean Lion was a monstrous lion that terrorized the hills around Nemea in Greece. Its golden fur was impervious to weapons, making it impossible to kill with ordinary arrows or blades, while its claws were sharper than mortal swords and could pierce even the strongest armour. Its origins vary between traditions: some accounts describe it as the offspring of Orthus and a monstrous female, while others name Typhon as its father. Another tradition claims that the lion was born from the Moon, when the goddess Selene cast it down at Hera’s request. Hera allowed the beast to roam her lands, knowing that it would become a formidable challenge for Heracles.

The Nemean Lion became the target of the first of Heracles’ twelve labours, imposed upon him by King Eurystheus. When Heracles first attacked the creature with his bow, his arrows bounced harmlessly off its golden hide. Realizing that ordinary weapons could not harm the beast, the hero drove it into its cave and blocked one of its two entrances. He then entered through the other opening and stunned the lion with his club. Finally, Heracles strangled the monster with his bare hands.

After killing the lion, Heracles discovered that he could not cut through its hide with his knife. According to tradition, the goddess Athena advised him to use one of the lion’s own claws to remove its skin. Heracles thereafter wore the impenetrable pelt as armour and its head as a helmet, making the lion’s hide a lasting symbol of his extraordinary strength. When he returned with the carcass, Eurystheus was so terrified that he ordered Heracles to present the results of his future labours outside the city gates. The king even had a large bronze jar made in which he could hide whenever the hero returned.

Chimera

by

Tradition: Greek Mythology
Alternative Names: Chimaera, Khimaira
Category: Lion

The Myth

The Chimera was a monstrous, fire-breathing hybrid that terrorized the land of Lycia in Asia Minor. Its body combined several fearsome animals: it had the head and forequarters of a lion, a goat’s head rising from its back, and a serpent for a tail. Some descriptions portray it as having three heads, with a lion at the front, a goat in the middle, and a serpent at the rear. The creature breathed blazing fire and was considered a terrible threat to both people and livestock. It was said to be the offspring of Typhon and Echidna, making it a sibling of other famous monsters, including Cerberus and the Lernaean Hydra.

The Chimera brought destruction to Lycia, killing cattle and devastating the countryside. King Iobates therefore ordered the hero Bellerophon to slay the monster, hoping that the dangerous task would lead to his death. Bellerophon, however, undertook the challenge with the help of Pegasus, the winged horse. Mounted on Pegasus, he soared above the Chimera and attacked it from the air, eventually killing the beast with his weapons.

The Chimera became one of the best-known monsters of Greek mythology, representing the terrifying union of different animals into a single creature. Its image appeared in ancient art, including pottery, sculptures, and mosaics depicting its battle with Bellerophon and Pegasus. Its name later came to describe any fantastic creature formed from parts of different animals.
