Euphronios is one of the rare Greek vase painters whose name has come down to us. An exceptional artist, he stopped painting at the height of his career to devote himself to making the vases he had once decorated. He was one of the main contributors to a major transformation that took place at the time: the transition from black-figure to red-figure painting. By comparing them with the known works of the painter, Alain Jaubert reconstructs his career and analyzes his pictorial style.
