Buckley's concern to expose the physical structure of a work can be seen in many of his paintings. In 'Triptych' this concern with structure and process was extended. The work demonstrates Buckley's wish, while making a painting, not to discard any materials but to employ all the intended components. Despite being composed of two units, 'Triptych' is so named because it originally consisted of three panels. During the making of the painting, these were dismembered and rearranged in order to create the work's present appearance. This idea also connects with the historical convention whereby triptychs were constructed so that they could be folded into a smaller format.
