For as long as collective memory has been an area of scholarly concern, the precise role of images as its vehicle has been asserted rather than explicated. This essay addresses the role of images in collective memory. Motivated by circumstances in which images, rather than words, emerge as the preferred way to establish and maintain shared knowledge from earlier times, it offers the heuristic of "voice" to help explain how images work across represented events from different times and places. The essay uses "voice" to elucidate how the visual becomes an effective mode of relay about the past and a key vehicle of memory.
