Euphronios is probably the best known of the early red-figure artists called the Pioneers. During the latter part of his career, he signs as potter rather than painter, and he collaborates with various painters of whom Onesimos is one of the most accomplished. The representation on the interior shows the almost coloristic effects that Onesimos achieved with dilute glaze as well as his marvelous characterization of Herakles- young, wide-eyed, jaunty, and finely turned out.
