These shrouded figures are hiding in plain sight, made all the more visible today by their efforts to make themselves invisible back then. As philosopher Jacques Derrida might put it, they enact ‘an erasure that allows what it obliterates to be read’. The figure is there, a muffled visual presence, but he or she is not exactly seeable, or at least not identifiable; they have made themselves invisible through a willed transfiguration from person into object. They are both there and not there, both opaque and an apparition, either/or and thus neither/nor, all at the same time.
