Andokides painter: The Andokides Painter was an ancient Athenian vase painter, active from approximately 530 to 515 B.C. His work is unsigned and his true name unknown.  He was identified as a unique artistic personality through stylistic traits found in common among several paintings.  This corpus was then attributed by John D. Beazley to the Andokides Painter, a name derived from the potter Andokides, whose signature appears on several of the vases bearing the painter's work.  He is often credited with being the originator of the red-figure vase painting technique.  To be sure, he is certainly one of the earliest painters to work in the style.  In total, fourteen amphorae and two cups are attributed to his hand.  Six of the amphorae are "bilingual", meaning they display both red-figure and black-figure scenes.
