Medea
Medea figures in the myth of Jason and the Argonauts, a myth known best from a late literary version worked up by Apollonius of Rhodes in the 3rd century BC and called the Argonautica. However, for all its self-consciousness and researched archaic vocabulary, the late epic was based on very old, scattered materials. Medea is known in most stories as an enchantress and is often depicted as a priestess of the goddess Hecate or a witch. The myth of Jason and Medea is very old, originally written around the time Hesiod wrote the Theogony. It was known to the composer of the  Little Iliad, part of the Epic Cycle.
