Untitled (1979) is indeed perhaps one of Jan Cox's most abstract pieces.  But even here we can recognize a motif that we also see recur in many other of his works.  The black, broken line flanked by the red bow sketching a passage or portal.

Jan Cox was familiar with Freud, and often made references to his theories in his texts.  In this vein, it is plausible to suggest that this door references the female.  In addition, we can also postulate that this stylized passage, seen from the perspective of Cox's humanist-dualistic philosophy of life, is not the one or the other, but the one and the other - namely, a representation of both the masculine and the feminine.

Untitled (1979) may be considered rather as an experiment in the run-up to the Calvary series, and has never before been exhibited.
