Urgency and spontaneity are essential elements of Jorn’s work. They can be seen in the roughly worked background and short, aggressive lines found in each of these engravings. In Untitled A they combine to form a vaguely figurative aspect to the central form. Untitled C takes the form of a wraithlike head with gaping mouth. Both works have echoes of children’s drawings and pre-historic art which were important influences on Jorn.
