As a lifelong resident of Lexington, Virginia, the burial place of Stonewall Jackson and Robert E. Lee, Sally Mann sought to reckon with the carnage of the Civil War. Photo­graphing the “death-hallowed ground” of battlefields in the early 2000s using equipment and processes reminiscent of the 19th century, she made apocalyptic images that suggest the final view of those who perished there. As if to bring the “deposit of fallen bodies, hopes, loves, joys, and fears” to the surface of her Battlefields pictures, Mann coated her prints with a varnish incorporating diatomaceous earth— the fossilized remains of tiny marine creatures.
