Vittore Carpaccio, The Sermon of St. Stephen
1514
Oil on canvas, 152 x 195 cm
Musée du Louvre, Paris
In Acts 7:2-53 St. Stephen summarizes Jewish history and concludes with a bitter denunciation of his "stiffnecked" listeners, "uncircumcised in heart," whose ancestors "have slain them who foretold of the coming of the Just One; of whom you have been now the betrayers and murderers."
As is common in paintings of this period, non-Christian denizens of the Middle East are pictured with turbans.
