Having posted the Death of Marat here some days ago I really do need to post its 'companion piece,' Charlotte Corday by Paul Jacques Aimé Baudry, painted 1858.
Corday was Marat's murderer. Wikipedia gives the reason for his murder. For those not familiar with the story of 'The Terror' Marat was a butcher. His murder deserved.
Note the change in styles between the two paintings, and the claustrophobia and disorder of this one, painted half-a-century later than the earlier one.
