If Not Rembrandt, Then His Cousin?

A number of paintings formerly attributed to Rembrandt, including such famous works as Saul and David and The Man in a Helmet, seem to form a stylistically distinct group that was executed by another hand. Although the author of these canvases cannot be established with certainty, several of them have striking affinities in handling and subject matter with the work of Rembrandt's cousin and pupil, Karel van der Pluym.
