Exekias (Ancient Greek: Ἐξηκίας, Exēkías) was an ancient Greek vase-painter and potter who was active in Athens between roughly 545 BC and 530 BC. Exekias worked mainly in the black-figure technique, which involved the painting of scenes using a clay slip that fired to black, with details created through incision. Exekias is regarded by art historians as an artistic visionary whose masterful use of incision and psychologically sensitive compositions mark him as one of the greatest of all Attic vase painters. The Andokides painter and the Lysippides Painter are thought to have been students of Exekias.
