Inspired by Seamus Heaney's poems, and notably by his version of the medieval Irish saga Buile Suibhne, the American photographer Rachel Giese has produced a stunning portfolio of pictures of the northern Irish landscape, covering the boundaries of Mad Sweeney's original kingdom of Dal-Arie. She has followed the clues to topography and the natural world in Sweeney's wanderings, and gathered together 34 photographs which Seamus Heaney has matched with extracts and quotations from his Sweeney Astray.
