A distinctive pattern of horizontal and vertical lines appears in the background of many of Eadweard Muybridge’s best-known photographs, giving his images of animal and human locomotion a strangely modern appearance, despite their being products of the 1880s. The lines also anticipate those adopted in the 20th century against which US criminals appear in police identification parades — which seems appropriate, given that a decade prior to taking these images, Muybridge himself was convicted of murder.
