04The myths

15 myths, each traced to its primary text and corpus sources, with 2 reviewed modern reworks linked where the evidence supports it.

Aeson announced that his newborn son Jason was dead. In secret, he removed the child from Iolcus and entrusted him to the centaur Chiron. Chiron raised Jason in the countryside, away from Pelias and the danger posed by his rule. Some accounts place Jason in the forest during this concealment.

Aeson had a claim to the throne. He was the son of Cretheus and might have succeeded him as king of Iolcus. Pelias, Aeson’s half-brother, had seized the throne instead. Pelias was the son of Tyro and Poseidon, so his position was disputed. In accounts that describe Pelias as a usurper, Jason’s concealment protected the child who stood in the line of succession.

Jason remained with Chiron until he reached manhood. Other heroes were also counted among Chiron’s pupils. When Jason was grown, he left the centaur and travelled towards Iolcus to claim his father’s throne.

On the journey, Jason reached the River Anauros. An old woman stood there, unable to cross without help. Jason carried her over the river on his shoulders. She was Hera in disguise, although he did not know this. The current swept away one of his sandals. Hera then became his protector.

Pelias had received a prophecy that a stranger wearing one sandal would cause him to lose his kingdom. When Jason appeared before him, Pelias recognised the danger. He sought to remove the young man without killing him and sent him to fetch the Golden Fleece from the grove sacred to Ares in Colchis.

    Quote

    Jason was secretly entrusted to Chiron, who raised him until manhood, after which he returned to Iolcus and was sent by Pelias to fetch the Golden Fleece.

    Apollodorus, The Library

Jason carried an old woman across a raging river. She was Hera in disguise, though Jason did not know it. As he bore her through the current, he lost one sandal. Hera then became his protector. Jason continued to Iolcus, wearing one sandal and carrying himself boldly. The people saw him enter the crowded marketplace and wondered whether he was Apollo, Aphrodite’s lord, or one of Poseidon’s sons. Pelias heard of the stranger and hurried to see him.

Pelias had been warned by an oracle that he would die at the hands of his kinsmen. He had also been told to beware of a man wearing only one sandal. When he saw Jason, he recognised the danger. Jason was the son of Aeson and the heir to Iolcus. He went to Pelias and demanded the kingdom. Pelias appeared to welcome him. He promised that Jason would become his heir and could marry whichever of his three daughters he chose.

Pelias then said that Jason must first perform an achievement worthy of the kingdom. He ordered him to bring back the Golden Fleece from Colchis. The fleece was the coat of a magical ram that had saved two children from Iolcus. The ram had been sacrificed to the gods, and its fleece had been taken to Colchis. It hung from a tree in a forest and was guarded by dragons. Pelias said that the dead Phrixus called to him and demanded that the fleece be brought home. This was a lie. He had taught his daughters to repeat the story and weep before Jason.

Jason had heard of the fleece and believed it almost impossible for a mortal to win. He accepted the challenge. He did not wish to begin a war with his uncle, and he welcomed the prospect of adventure. He also knew that Hera favoured him. Since Colchis could be reached only by sea, Jason began building a great ship. He named it the Argo. News of the quest spread through Greece, and many young heroes sought to join him. When the Argo was ready, Jason had a determined crew and prepared to sail for Colchis.

A table was set before Phineus, but the Harpies immediately swooped down with loud cries. They snatched away most of the food and left the rest foul-smelling and impossible to eat. Phineus, an old and blind prophet, suffered this punishment whenever he tried to dine. Apollo had given him the power to foretell the future. Zeus punished him because he revealed what the god intended to keep hidden. The Harpies were female winged creatures known as the hounds of Zeus.

The Argonauts had come to Phineus for directions on their voyage to Colchis. He agreed to advise them if they freed him from the Harpies. He knew that two members of the crew could defend him, Zetes and Calais, the winged sons of Boreas, the North Wind. When the Harpies returned, the brothers drew their swords and pursued them through the air. The Harpies fled across the sky, driven away by the sons of Boreas.

Phineus was then able to eat. He thanked Jason and the Argonauts by telling them about the dangers ahead. The Clashing Rocks lay across their route. These enormous rocks moved apart and then crashed together, destroying anything caught between them. Phineus said that the Argonauts should first send a bird through the passage. If it survived, the Argo could follow its course. He gave them a dove, and the crew returned to their ship with his instructions.

When they reached the Clashing Rocks, Jason released the dove as the rocks shifted and churned the sea. The bird flew through the opening, and the Argonauts followed its path with the Argo.

Jason hurried to a sacrifice that Pelias was holding by the sea for Poseidon. He had been living in the countryside because he enjoyed farming. As he crossed the River Anauros, the current swept away one of his sandals. He reached the sacrifice wearing only one. Pelias recognised the sign from an oracle, which had warned him to fear a man with one sandal. Jason was the son of Aison, who was descended from Cretheus. He lived at Iolcos, where Pelias ruled after succeeding Cretheus.

Pelias sent Jason to fetch the Golden Fleece from Colchis. The fleece was the coat of a magical ram that had saved two children from Iolcos. The ram had been sacrificed to the gods, and its fleece was kept as a prize in Colchis. It hung from a tree in a forest and was guarded by dragons. Pelias said that the fleece should be brought back to Iolcos, though he also expected the journey to destroy Jason. Jason accepted the challenge and prepared to sail across the sea.

He employed Argus to build a vessel large enough to carry fifty men. Such a ship was considered a huge undertaking because Greek sailors generally used small boats or canoes hollowed from tree trunks. When the vessel was finished, Jason named it the Argo, after its builder. News of the expedition spread through Greece, and Jason invited young men who wished to join him.

The crew included Heracles, Theseus, Orpheus, and Nestor. Many others joined them, and they became known as the Argonauts, after the name of their ship. With Jason in command, the Argo left the shore and began the voyage towards Colchis.

    Argus built the Argo for Jason, who gathered a crew of heroes and sailed with them towards Colchis to seek the Golden Fleece.

Phineus told the Argonauts what route to take and warned them about the Symplegades, the Clashing Rocks. The rocks were enormous and were driven together by the winds. They closed the passage through the sea, while thick mist swirled around them and the crash of their collision filled the air. Anything caught between them would be destroyed. Phineus said that it was impossible even for birds to pass through safely.

He advised Jason to release a dove between the rocks. If the bird passed through unharmed, the Argonauts could follow its path. If it was destroyed, they were to make no attempt to force the passage. Phineus gave them a dove, and the Argonauts returned to the Argo. When the ship came close to the rocks, Jason watched the boulders move and churn the water around them. He released the dove from the prow.

The dove flew between the Clashing Rocks as they came together. Only the tips of its tail feathers were cut off. Jason and the crew waited until the rocks had drawn apart again. Then they rowed the Argo through the opening with all their strength. The ship followed the dove’s course and passed safely between the rocks. The rocks closed behind it, leaving the Argo beyond the dangerous passage. Phineus’s advice allowed Jason and the Argonauts to continue their voyage towards Colchis.

Jason stood before King Aeëtes in Colchis and asked for the kingdom’s Golden Fleece. Aeëtes hated outsiders and answered with a challenge. Jason had to harness the king’s fire-breathing oxen, whose hooves were made of metal, and make them plough a field. He then had to sow the furrows with dragon’s teeth. Armed men would grow from the teeth, and Jason had to kill them all before he could claim the Fleece.

Medea, Aeëtes’ daughter, saw Jason and fell in love with him. She was a priestess of Hecate, skilled in magic herbs, charms, and incantations. That night, she made an enchanted oil and went secretly to Jason’s ship, the Argo. She told him that the oil would protect him from harm for one day. If he rubbed it over his body, he would be safe. If he covered his weapons with it, they would become all-powerful. She also told him how to defeat the warriors born from the dragon’s teeth. When they gathered around him, he should throw a large stone among them. They would mistake one another for enemies and fight among themselves.

Jason completed the ploughing and sowed the teeth. Armed men sprang from the earth and rushed at him. He followed Medea’s advice and threw a stone into their midst. The warriors turned upon one another and fell beneath their own spears. Jason had won the contest, but Aeëtes was enraged. The king returned to his palace, planning treachery and refusing to let the heroes take the Fleece.

Medea then decided to leave with Jason. She went to the Argo and begged Jason and his companions to take her with them. She warned them that they had to seize the Fleece and escape at once, or Aeëtes would kill them. A terrible serpent guarded the Fleece, but Medea helped Jason overcome its protection. Jason took the Fleece, and Medea left Colchis with him after promising to become his wife.

    Medea gave Jason an enchanted protection and instructions for overcoming the armed men, then helped him take the Fleece and fled with him from Colchis.

    Ovid, Metamorphoses

The guardian dragon hissed and sizzled as Jason approached the tree. Its crested head, hooked claws, and triple tongue guarded the Golden Fleece. Medea came to his side and used her sorcery against it. One account says that she sang a spell. Another says that she sprinkled the dragon with herbs and drugs, then spoke words that brought sleep. The creature’s head sank down, its coils relaxed, and its eyes closed. Jason climbed over it, seized the fleece, and returned with Medea to the Argo.

They had reached Colchis after sailing past the River Thermodon and the Caucasus to the River Phasis. Jason had come because Pelias had ordered him to bring the fleece to Iolcos. Aeetes, its keeper, agreed to surrender it only if Jason first yoked two huge bulls with bronze hooves and fire breathing mouths. The bulls were a gift from Hephaestus. Jason then had to plough the field of Ares and sow it with dragon’s teeth. Armed men would spring from the earth and attack him.

When Jason was at his wit’s end, Medea, the daughter of Aeetes and Eidyia, fell in love with him. She feared that the bulls would kill him, so she secretly offered her help. Jason completed the tasks, but Aeetes still refused to give up the fleece and planned to burn the Argo with its crew. Medea therefore guided Jason to the tree by night. Her brother Apsyrtus joined them. The Argonauts sailed away during the night, carrying the fleece and Medea, while Aeetes pursued them.

    Jason carried off the Golden Fleece with Medea and escaped from Aeëtes to rejoin the Argonauts on the Argo.

    Ovid, Metamorphoses

Jason reached the River Anauros on his way to Iolcos, where he intended to claim the throne. An old woman stood on the bank and needed help to cross. Jason did not know that she was Hera, disguised as a helpless mortal. He lifted her and carried her into the water. As they reached the middle of the river, his foot sank into the mud and one sandal came loose. He left it behind and carried the woman to the far bank.

When Jason looked at her again, the old woman had become Hera, the Queen of Olympus and wife of Zeus. She told him that she would aid him because he had helped her when he believed her to be an old woman in need. She instructed him to call on her in danger, saying that the Immortals would not forget his kindness. Then she rose from the earth like a tall white cloud and passed over the mountain peaks towards Olympus.

Jason continued towards Iolcos with one sandal. He remembered that Chiron had told him to speak harshly to no one he met. Jason took this as proof that the centaur had foreseen what would happen. His father, Aeson, had been the rightful heir, but Aeson’s half-brother Pelias had seized the throne. A prophecy had warned Pelias that a stranger wearing one sandal would cause him to lose his kingdom.

When Pelias saw Jason, he recognised the omen and feared for his rule. He wished to remove the young man without murdering him, so he sent Jason to fetch the Golden Fleece. It lay in a grove sacred to Ares in Colchis, a distant land from which Pelias expected Jason not to return.

The Colchian ships overtook the Argo after Jason and Medea had escaped with the Fleece. The accounts of what followed differ. In one, Medea killed her half-brother Apsyrtus and threw his dismembered body into the sea. The pursuers stopped to gather the remains for burial. In another, Apsyrtus followed in one of the pursuing ships. Medea persuaded him that Jason had abducted her and drew him ashore. Jason then killed him from ambush. Without Apsyrtus, the Colchians were defeated and the Argonauts escaped.

The Argo passed between Scylla and Charybdis. It then reached the land of the Phaeacians, where some Colchians found the ship and demanded that King Alcinoos surrender Medea. Alcinoos decided that she should remain with Jason if she had already slept with him, but should be returned to Colchis if she had not. Jason and Medea were therefore married before the decision was carried out. In one account, they had first been purified of Apsyrtus’s murder by Circe. Another places their marriage and purification on the island of the Phaeacians.

The voyage continued. As the Argo passed the Sirens, Orpheus sang against their song. Boutes alone swam towards them, but Aphrodite carried him away and settled him at Lilybaeum. Thetis guided the ship past the Wandering Rocks with the help of the Nereids, after Hera summoned her. The Argonauts also skirted Thrinacia, the island of the Sun’s cattle.

On the return to Iolcus, the Argo was attacked by Talos, the bronze guardian of Crete. Medea drugged him and removed the pin from his ankle, allowing the fluid to drain from his single vein. In another account, Hades caused Talos to graze his ankle against a rock. Jason and Medea reached Iolcus together. There, Medea helped Jason take revenge on Pelias, who had refused to surrender the throne and had caused the deaths of Jason’s family. She deceived Pelias’s daughters into killing and dismembering him. A torch signal brought the Argonauts from hiding, and they captured the city.

    Jason and Medea were married before Alcinoos decided whether she should return to Colchis, and they later reached Iolcus together after their voyage.

    Ovid, Metamorphoses

After Jason and Medea had taken revenge on Pelias, they fled Iolcos and sought refuge in Corinth. King Creon welcomed them there. He offered his daughter Creusa to Jason in marriage. Jason accepted, abandoning Medea and their children. He claimed that the new marriage would improve his position and give him greater security in Corinth.

Medea could not accept this decision. The Corinthians regarded her as a dangerous sorceress, and she was threatened with banishment. She prepared wedding gifts for Creusa. She gave her children a poisoned robe and headdress to take to the bride. When Creusa put them on, her flesh burst into flame and dissolved.

Creon tried to save his daughter. The poison bound him to her garments, and he died with her. Medea then killed her own children with her hands. One account places the murders before Jason’s eyes. They were carried out as revenge for his desertion and his marriage to Creusa.

Jason’s decision brought about the deaths of Creusa, Creon, and the children he had had with Medea. The accounts end with Medea’s revenge in Corinth. They do not present Jason’s new marriage as a peaceful settlement. It leads directly to the destruction of his household and to Medea’s final act against him.

    Jason’s abandonment of Medea for Creusa led Medea to destroy the bride, Creon, and the children she had borne Jason.

    Ovid, Metamorphoses

The Argive army halted outside a forest at Nemea, which was governed by King Lycurgus. The army had been divided among seven leaders: Adrastus, Hippomedon, Parthenopaeus, Capaneus, Polynices, Tydeus, and Amphiaraus. The soldiers were short of water and searched for a spring. They saw a majestic woman seated on a tree trunk with an infant in her arms. Her noble appearance led them to think that she was a goddess. She told them that she was Hypsipyle, queen of the Lemnians. She had been carried away by pirates and sold as a slave to Lycurgus. She was serving as nurse to his infant son.

When the warriors asked for water, Hypsipyle laid the child in the grass and led them to a hidden spring in the forest. This meeting places her captivity in Nemea, during the Argives’ march, and identifies Lycurgus as her owner. It also gives her a role at his court, where she cared for his infant son.

The same account gives a different ending for her story. After her actions on Lemnos were discovered, Hypsipyle was exiled. Pirates then captured her and sold her to Lycurgus. She was later rescued, bringing her enslavement to an end. The sources differ over the events that led to her exile, the fate of Thoas, and the manner in which she entered Lycurgus’s possession. One version presents her as sold by pirates before the Argives found her in Nemea. Other versions preserve different details, so the sequence after her exile is not identical in every account.

After taking the Golden Fleece, Jason and the Argonauts sailed towards Crete and tried to find shelter there. Talos saw the Argo approaching and ran around the island, as he did three times each day. He came towards the ship, hurling stones at it. In another account, he stood on a western cape and shouted that the crew were pirates and robbers who would die if they landed. The heroes answered that they wanted only food and water, but Talos continued to threaten them.

Talos was a giant made of bronze. His body and limbs could not be harmed, except at one place on his ankle. A single vein ran from his neck to his ankle, and a bronze nail closed its end. He guarded Crete for Minos, or, in another tradition, for Europa after Zeus had given him to her. He kept watch by circling the island three times each day. He could attack invaders with stones, and his burning body could kill them by crushing them in an embrace.

Medea, who was travelling with the Argonauts, tricked Talos and caused his death. One account says that she drugged him until he became mad. Another says that she promised to make him immortal and then pulled out the bronze nail. His ichor flowed from the open vein and he died. Some accounts say that Poias killed him by shooting an arrow into his ankle. With Talos dead, the danger preventing the Argonauts from landing at Crete was removed.

At Jason's request, Medea agreed to restore the youth of his father, Aeson. Jason offered to give some years of his own life to lengthen Aeson's, but Medea refused to take them from him. She said that her art might extend Aeson's life without shortening Jason's. At the next full moon, she went out alone while all creatures slept and the leaves remained still. She addressed the stars and the moon, then invoked Hecate, Tellus, and the gods of the woods. She called on the powers connected with the earth and with plants used in enchantments.

Medea then ordered Aeson to be brought out. She put him into a deep sleep with a charm and had him laid on a bed of herbs, as if he were dead. Jason and everyone else were kept away so that no uninitiated person could see the rites. With her hair streaming, Medea moved three times around the altars. She dipped burning twigs in blood and placed them on the altars to burn.

She prepared a cauldron and filled it with magical herbs, seeds, flowers with sharp juices, stones from the distant East, and sand from the shore of the ocean. She added frost gathered by moonlight, the head and wings of a screech owl, the entrails of a wolf, pieces of tortoise shell, the liver of stags, and the head and beak of a crow. She also put in many other substances that the account does not name. She boiled everything together and stirred it with a dry olive branch.

After the ritual, Medea used the prepared mixture in her work on Aeson. The old man was restored to youth, and his life was lengthened without any years being taken from Jason.

    Medea restored Aeson’s youth through a nocturnal rite and a magical mixture, without shortening Jason’s life.

    Ovid, Metamorphoses

Jason came to Iolcos to claim the throne that Pelias had taken from his father, Aeson. He demanded justice. Pelias promised to surrender the kingdom if Jason brought back the Golden Fleece, the magical skin of a ram, from distant Colchis. Pelias expected the journey to kill him, but Jason gathered an expedition that included several heroes, among them Heracles, and returned with the fleece and Medea.

Medea had used her arts for a good purpose before taking revenge on Pelias. She restored Aeson, Jason’s father, by preparing a cauldron and using her knowledge of magic. Pelias’s daughters loved their father. When they saw what Medea had done for Aeson, they asked her to restore Pelias in the same way.

Medea pretended to agree. She prepared a cauldron and asked the daughters to bring an old sheep. They plunged it into the mixture. Soon they heard bleating. When Medea removed the cover, a lamb leapt out and ran into the meadow. The daughters were delighted by the display and chose a time for their father’s treatment.

Medea then prepared the cauldron differently. During the night, she entered with Pelias’s daughters and put only water and a few simple herbs into it. The daughters followed her instructions and placed Pelias in the cauldron, expecting him to emerge young again. The transformation did not take place. Their attempt killed Pelias, and Jason and Medea gained revenge for his seizure of Aeson’s kingdom.

    Medea persuaded Pelias’s daughters to put him into a cauldron for renewal, but her deception caused his death and brought revenge to Jason.

    Ovid, Metamorphoses

Aeson secretly removed his infant son Jason from Iolcos after Aeson’s half-brother Pelias seized the throne. Pelias feared that Jason, the rightful heir, would threaten his rule. Aeson made it known that the child was dead, then brought him to the centaur Chiron to be raised. Chiron educated Jason in medicine, warfare, and the skills expected of a hero. Jason grew to adulthood among Chiron’s pupils, who included other heroic figures.

When Jason was of age, he left Chiron and returned to Thessaly to claim his father’s throne. On the journey, he reached the raging River Anauros. An old woman asked him to carry her across because she lacked the strength to cross alone. She was Hera in disguise. Jason carried her on his shoulders but lost one sandal in the current. Hera then became his protector.

Pelias had been warned by a prophecy that a stranger wearing one sandal would cause him to lose the kingdom. When he saw Jason, he feared that the prophecy had come true. Rather than kill him, Pelias sent him to Colchis to fetch the Golden Fleece, which hung in a grove sacred to Ares. Another account says that Pelias agreed to return the throne if Jason brought back the fleece.

Jason gathered a crew of heroes and sailed on the Argo, a ship built with Athena’s help. In Colchis, King Aeetes promised the fleece if Jason completed a series of impossible tasks. With help from Aeetes’ daughter Medea, who knew magic, Jason completed them. Aeetes then refused to surrender the fleece, so Jason stole it and fled with Medea. He later became impure in the eyes of the gods after the murder of Medea’s brother, Apsyrtus, and did not ascend the throne of Thessaly.

    Quote

    Chiron raised and educated Jason, who later sailed with the Argonauts, won the Fleece through Medea’s help, and escaped with her after Aeetes refused to surrender it.

    Apollodorus, The Library

Works that draw on more of the mythology than any single story: full retellings of the saga, and worlds built out of the material.

Argonauts

film

The ship-building heroes, the voyage past the Symplegades and Sirens, the Colchian trials, and Medea's help in winning the fleece all appear, compressed from across the Argonautica rather than any one episode.

Argonavtebi

film

Pelias murdering his way to the throne and sending Jason for the Golden Fleece as a legitimacy test survives, but the voyage adds invented stops (a singing contest with King Amicus, Heracles staying behind for an Amazon queen) and resolves the fleece by marriage rather than theft.

Atlantis

television

Only the name Jason, his eventual marriage to Ariadne, and a shipboard past carry over; the Argonaut quest, the Fleece, and Medea are absent.

The Giants of Thessaly

film

Jason and the Argonauts' voyage in search of the Golden Fleece survives as the premise, along with a Lemnos stop, but the wife is named Creusa rather than Medea, a Cyclops from the Odyssey is grafted in, and an invented court-intrigue plot replaces the myth's ending.
