A similar issue was raised by Simon Schama in his book "Rembrandt's Eyes" concerning the verification of titles associated with the subject matter depicted in Rembrandt's works. For example, the exact subject being portrayed in "Aristotle with a Bust of Homer" (recently retitled by curators at the Metropolitan Museum) has been directly challenged by Schama applying the scholarship of Paul Crenshaw. Schama presents a substantial argument that it was the famous ancient Greek painter Apelles who is depicted in contemplation by Rembrandt and not Aristotle.
