Classic tale
The Greek tale of Jason and the Golden Fleece has been told for 3,000 years. It's a classic hero's quest tale - a sort of ancient Greek mission impossible - in which the hero embarks on a sea voyage into an unknown land, with a great task to achieve. He is in search of a magical ram's fleece, which he has to find in order to reclaim his father's kingdom of Iolkos from the usurper King Pelias.
The Greeks have retold and reinterpreted it many times since, changing it as their knowledge of the physical world increased.
The story is a set a generation before the time of the Trojan War, around 1300 BC, but the first known written mention of it comes six centuries later, in the age of Homer (800 BC). The tale came out of the region of Thessaly, in Greece, where early epic poetry developed. The Greeks have retold and reinterpreted it many times since, changing it as their knowledge of the physical world increased.
No one knows for sure where the earliest poets set the adventure, but by 700 BC the poet Eumelos set the tale of the Golden Fleece in the kingdom of Aia, a land that at the time was thought to be at the eastern edge of the world. At this point the Jason story becomes fixed as an expedition to the Black Sea. The most famous version, penned by Apollonius of Rhodes, who was head of the library at Alexandria, was composed in the third century BC, after the invasion of Asia by Alexander the Great.
Since the 1870s a series of excavations at Mycenae, Knossos, Troy and elsewhere has brought the Greek Heroic Age - the imaginary time when the great myths were set - to life. The archaeologists' discoveries of Bronze Age (2300-700 BC) artefacts made it clear that the Greek myths and epic poems preserve the traditions of a Bronze Age society, and may refer to actual events of that time. The story could also perhaps represent an age of Greek colonisation around the shores of the Black Sea.
