Hollstein 7. Note: Detail taken from a larger mezzotint by Prince Rupert of the Rhine 'The Great Executioner with the Head of Saint John the Baptist', 1658, after a painting (now in the Alte Pinakothek, Munich) considered at the time to be by Ribera but now thought to be by an artist in his circle. Prince Rupert was one of the very first practitioners of the technique of mezzotint, inventing the 'rocker', the tool used to roughen the printing plate.Please refer to department for condition report
