The Medea Group decorated vases in the black-figure technique in Athens in the late 500s B.C. They often painted scenes of the hero Herakles and frequently decorated small amphorae, both of which were especially popular at this time. As with most ancient artists, the true names of the painters in the Medea Group are unknown; their work is identified only by stylistic traits. The Group takes its name from an amphora in the British Museum showing a scene of the sorceress Medea rejuvenating a ram. Although individual artists such as the Bareiss Painter can be discerned within the Medea Group, the styles of most members of the group so closely resemble one another that they cannot be separated.
