Jason (Greek: Iάσων, Etruscan: Easun) was a late ancient Greek mythological figure, famous as the leader of the Argonauts and their quest for the Golden Fleece. He was the son of Aeson, the rightful king of Iolcus. He was married to the sorceress Medea.

Jason is considered to be one of the heroes of Greek mythology, along with such others as Herakles and Odysseus.

Jason appeared in various literature in the classical world of Greece and Rome, including the epic poem Argonautica and tragedian play, Medea. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the film Jason and the Argonauts.

Jason has connections outside of the classical world, as he is seen as being the mythical founder of the city of Ljubljana, the capital of Slovenia.

Pelias (Aeson’s half-brother) was very power-hungry, and he wished to gain dominion over all of Thessaly. Pelias was the product of a union between their shared mother, Tyro (“high born Tyro”) the daughter of Salmoneus, and the sea god Poseidon. In a bitter feud, he overthrew Aeson (the rightful king), killing all the descendants of Aeson that he could. He spared his half-brother for unknown reasons. Alcimede I (wife of Aeson) already had an infant son named Jason whom she saved from being killed by Pelias, by having women cluster around the newborn and cry as if he were stillborn. Alcimede sent her son to the centaur Chiron for education, for fear that Pelias would kill him - she claimed that she had been having an

affair with him all along. Pelias, still fearful that he would one day be overthrown, consulted an oracle, which warned him to beware of a man with one sandal.

Many years later, Pelias was holding games in honor of the sea god and his alleged father, Poseidon, when Jason arrived in Iolcus and lost one of his sandals in the river Anauros (“wintry Anauros”), while helping an old woman (the Goddess Hera in disguise), to cross. She blessed him for she knew, as goddesses do, what Pelias had up his sleeve. When Jason entered Iolcus (modern-day city of Volos), he was announced as a man wearing one sandal. Jason, knowing that he was the rightful king, told Pelias that and Pelias said, “To take my throne, which you shall, you must go on a quest to find the Golden Fleece.” Jason happily accepted the quest.

Jason assembled a great group of heroes, known as the Argonauts after their ship, the Argo. The group of heroes included the Boreads (sons of Boreas, the North Wind) who could fly, Heracles, Philoctetes, Peleus, Telamon, Orpheus, Castor and Pollux, Atalanta, and Euphemus.

  The Harpies

The isle of Lemnos is situated off the Western coast of Asia Minor (modern day Turkey). The island was inhabited by a race of women who had killed their husbands. The women had neglected their worship of Aphrodite, and as a punishment the goddess made the women so foul in stench that their husbands couldn’t bear to be near them. The men then took concubines from the Thracian mainland opposite, and the spurned women, angry with Aphrodite, killed every male inhabitant while they slept. The king, Thoas, was saved by Hypsipyle, his daughter, who put him out to sea sealed in a chest from which he was later rescued. The women of Lemnos lived for a while without men, with Hypsipyle as their queen.

During the visit of the Argonauts the women mingled with the men creating a new “race” called Minyae. Jason fathered twins with the queen. Heracles pressured them to leave as he was disgusted by the antics of the Argonauts. He hadn’t taken part, which is truly unusual considering the numerous affairs he had with other women.

After Lemnos the Argonauts landed among the Doliones, whose king Kyzicos treated them graciously. The Argonauts departed, losing their bearings and landing again at the same spot that night. In the darkness, the Doliones took them for enemies and they started fighting each other. The Argonauts killed many of the Doliones, among them the king Kyzicos. Kyzicos’ wife killed herself. The Argonauts realized their horrible mistake when dawn came.

When the Argonauts reached Mysia, they sent some men to find food and water. Among these men was Heracles’ servant, Hylas. The nymphs of the stream where Hylas was collecting were attracted to his good looks, and pulled him into the stream. Heracles returned to his Labors, but Hylas was lost forever. Others say that Heracles went to Colchis with the Argonauts and he got the Golden Girdle of the Amazons and slew the Stymphalian Birds at that time.

Soon Jason reached the court of Phineus of Salmydessus in Thrace. Phineus had been given the gift of prophecy by Apollo, but was later given the choice of being blind and having a long life, or having sight and having a short life, for revealing to humans the deliberations of the gods. He chose to be blind. Helios the sun god sent the Harpies, creatures with the body of a bird and the head of a woman, to prevent Phineus from eating any more than what was necessary to live, because he was enraged that Phineus had chosen to live in a continual state of darkness than live in the sun he provided. Jason took pity on the emaciated king and killed the Harpies when they returned (In other versions Calais and Zetes chase the Harpies away). In return for this favor, Phineus revealed to Jason the location of Colchis and how to cross the Symplegades, or The Clashing Rocks, and then they parted.

The only way to reach Colchis was to sail through the Symplegades (Clashing Rocks), huge rock cliffs that came together and crushed anything that traveled between them. Phineus told Jason to release a dove when they approached these islands, and if the dove made it through, to row with all their might. If the dove was crushed, he was doomed to fail. Jason released the dove as advised, which made it through, losing only a few tail feathers. Seeing this, they rowed strongly and made it through with minor damage at the extreme stern of the ship. From that time on, the clashing rocks were forever joined leaving free passage for others to pass.

Jason arrived in Colchis (modern Black Sea coast of Georgia) to claim the fleece as his own. King Aeetes of Colchis promised to give it to him only if he could perform three certain tasks. Presented with the tasks, Jason became discouraged and fell into depression. However, Hera had persuaded Aphrodite to convince her son Eros to make Aeetes’s daughter, Medea, fall in love with Jason. As a result, Medea aided Jason in his tasks. First, Jason had to plow a field with fire-breathing oxen, the Khalkotauroi, that he had to yoke himself. Medea provided an ointment that protected him from the oxen’s flames.

Sleepless Dragon

Then, Jason sowed the teeth of a dragon into a field. The teeth sprouted into an army of warriors. Medea had previously warned Jason of this and told him how to defeat this foe. Before they attacked him, he threw a rock into the crowd. Unable to discover where the rock had come from, the soldiers attacked and defeated one another. His last task was to overcome the Sleepless Dragon that guarded the Golden Fleece. Jason sprayed the dragon with a potion, given by Medea, diluted from herbs. The dragon fell asleep, and Jason was able to seize the Golden Fleece. He then sailed away with Medea. Medea had to distract her father, who chased them, as they fled by killing her brother Apsyrtus and throwing pieces of his body into the sea, which Aeetes had to stop for and gather. In another version, Medea lured Apsyrtus into a trap. Jason kills him, chops off his fingers and toes, and buries the corpse. In any case, Jason and Medea escaped.

On the way back to Iolcus, Medea prophesized to Euphemus, the Argo’s helmsman, that one day he would rule Libya. This came true through Battus, a descendant of Euphemus. Zeus, as punishment for the slaughter of Medea’s own brother, sent a series of storms at the Argo and blew it off course. The Argo then spoke and said that they should seek purification with Circe, a nymph living on the island called Aeaea. After being cleansed, they continued their journey home.

Chiron had told Jason that without the aid of Orpheus, the Argonauts would never be able to pass the Sirens — the same Sirens encountered by Odysseus in Homer’s epic poem the Odyssey. The Sirens lived on three small, rocky islands called Sirenum Scopuli and sang beautiful songs that enticed sailors to come to them, which resulted in the crashing of their ship into the islands. When Orpheus heard their voices, he drew his lyre and played music that was more beautiful and louder, drowning out the Sirens’ bewitching songs.

The Argo then came to the island of Crete, guarded by the bronze man, Talos. As the ship approached, Talos hurled huge stones at the ship, keeping it at bay. Talos had one blood vessel, which went from his neck to his ankle, bound shut by only one bronze nail (as in metal casting by the lost wax method). Medea cast a spell on Talos to calm him; she removed the bronze nail and Talos bled to death. The Argo was then able to sail on.

Medea, using her sorcery, claimed to Pelias’ daughters that she could make their father younger by chopping him up into pieces and boiling the pieces in a cauldron of water and magical herbs. She demonstrated this remarkable feat with a sheep, which leapt out of the cauldron as a lamb. The girls, rather naively, sliced and diced their father and put him in the cauldron. Medea did not add the magical herbs, and Pelias was dead.

In Corinth, Jason became engaged to marry Creusa (sometimes referred to as Glauce), a daughter of the King of Corinth, to strengthen his political ties. When Medea confronted Jason about the engagement and cited all the help she had given him, he retorted that it was not she that he should thank, but Aphrodite who made Medea fall in love with him. Infuriated with Jason for breaking his vow that he would be hers forever, Medea took her revenge by presenting to Creusa a cursed dress, as a wedding gift, that stuck to her body and burned her to death as soon as she put it on. Creusa’s father, Creon, burned to death with his daughter as he tried to save her. Then Medea killed the two boys that she bore to Jason, fearing that they would be murdered or enslaved as a result of their mother’s actions. When Jason came to know of this, Medea was already gone; she fled to Athens in a chariot sent by her grandfather, the sun god Helios.

Later Jason and Peleus, father of the hero Achilles, would attack and defeat Acastus, reclaiming the throne of Iolcus for himself once more. Jason’s son, Thessalus, then became king.

Because he broke his vow to love Medea forever, Jason lost his favor with Hera and died lonely and unhappy. He was asleep under the stern of the rotting Argo when it fell on him, killing him instantly. The manner of his death was due to the deities cursing him for breaking his promise to Medea.
