“ Opie seems to have been self-taught, and no one knows how he took his bent toward broad masses of light and shade and rather coarse handling. It is easy to say that he was influenced by Rembrandt and Caravaggio, but there is no record that he knew anything about either of these painters. Indeed, it is more reasonable to assume that his hand was rather coarse by nature, and that he painted in broad masses because he had neither the delicacy nor the skill to paint otherwise. He never at any time approximated a worker in cloisonné. ”
