Merrin, an elderly Irish
priest and
paleontologist on an
archeological dig in
Iraq, finds images of the demon
Pazuzu and subsequently experiences other unusual phenomena. He had previously faced the demon many years before during an exorcism in
Africa. The find sparks a premonition that he will battle the demon again in a distant land. Merrin does not appear again until much later in the novel, when he joins the protagonist, Father
Damien Karras, in
Washington, D.C., to exorcise the demon from the body of a young girl (
Regan MacNeil). Merrin, who has a
heart disease for which he takes
nitroglycerin, dies during the ritual, leaving the inexperienced Karras to complete the exorcism himself. Merrin is loosely based on the British archaeologist
Gerald Lankester Harding, though in the film he is played by
Max von Sydow with a noticeably Irish accent. This was later parodied by
James Woods in the film
