“A picture is worth a thousand words” is perhaps today’s best-known cliché about visual objects. It also encapsulates numerous assumptions about the rhetorical functions of the visual.1 We start with it here not because we buy the cliché but because its ubiquity in US visual vernacular tells us a great deal about how people [in the United States, at least] perceive the rhetorical force of pictures. Because this chapter is about how shared sight links people to one another, beginning with a commonplace about sight helps illuminate the actual and presumed rhetorical functions of the visual for community building.
The cliché, “a picture is worth a thousand words,” emphasizes the indexical power of visual objects: This happened. This is real. A picture, in the cliché, is a truth claim, and looking at pictures is a mode of information gathering.2 The cliché, in other words, names witnessing as a primary rhetorical function of the visual. Apprehending what a picture shows, viewers enter into relationship with the subject matter and take on a sort of responsibility toward it. In this sense, both pictures and the process of seeing act on viewers via what the Greek rhetoricians called ekphrasis: vivid or lively description. Witnessing “brings before the eyes” what must be seen in order to be understood, acted upon, or made real. That belief that vision entails witnessing, and that witnessing carries obligation, power, and access to the real, are fundamental presumptions of Western visual culture.
Now, obviously, that “witnessing” function of the visual could find a home in either of the two previous chapters, alongside the collections of visual functions we have categorized as pedagogical-deliberative and catalytic. When documentary photographs are brought before decision-makers as pieces of evidence that demand policy action—a sort of “visual rhetoric event” that has inspired many articles and books about visual rhetoric3—they invite viewers to serve as witnesses toward both catalytic and deliberative ends: By seeing, viewers are asked to indict what has happened. Having been seen, the pictures then point toward necessary change.
More fundamentally, however, the rhetorical function of the visual that is identified by “a picture is worth a thousand words” is one where viewers are asked, as witnesses, to participate in a common reality. This rhetorical function highlights how seeing makes a claim on viewers, engaging them in something larger by virtue of having seen. Witnessing, as a key visual phenomenon, is, in this sense, an epideictic function of the visual. It is exemplary of the circumference-drawing work of rhetoric that ancient Greek rhetoricians described as speech of praise and blame.
Rhetoricians have found this epideictic function alluring even as we have cast doubt on the truth value of pictures. No visual scholar worth their salt would forget that pictures have always been infused with symbolism, manipulated, and falsified. A picture may be worth a thousand words, we shrug, but which thousand words? The image vernaculars of the late twenthieth and early twenty-first centuries make clear that scholars are not the only ones who are skeptical. The prevalence of terms like photoshopping, filters, face swap, and deepfakes make clear that few if any of us are comfortable with the truth of the pictures around us.

And yet, even the most skeptical of us are also affected by the visual activities that Margaret LaWare calls “witness[ing] the present” and places within the community-forming realm of the epideictic. Such visual engagement “illuminat[es] [a] community’s inherent reality,” LaWare writes, and she calls that community-forming, witness-driven function of the visual, “visual epideictic.”4 Scholars not explicitly invoking Aristotle’s term have likewise emphasized the role the visual plays in building up communities and establishing their borders—asking people to “bear witness to [their] historical legacy as well as [their] present.”5 LaWare’s initial elaboration of the visual’s epideictic function was celebratory: It focused on how marginalized communities can use public display of cultural values as a tool for building solidarity. Subsequent scholarship in this vein (including LaWare’s own return to the same site a decade later) makes clear that identifications driven by witnessing can turn in other directions and that visual epideictic’s pictures of praise and blame are available for good and for ill.6 For this reason, rhetorical scholars continue to be fascinated by the slippery, untrustworthy, yet powerful rhetorical function of making common sight.

Because, traditionally, the epideictic was separated from the institutional, productive functions of the polis—policy making (see chapter 1) and judicial determination (see chapter 2)—, it was long framed as the least necessary (and most disreputable) of the three Aristotelian branches. In the last several decades, however, rhetoricians have drawn attention to the generative potential of the epideictic, particularly—though not exclusively—in imperial contexts.7 Scholars of visual rhetoric have been particularly drawn to the epideictic, perhaps because of that function’s deep connection to witnessing practices and, thereby, to vision. While vision’s catalytic capacity might be the most celebrated function of the visual in existing rhetorical scholarship, community formation is its most readily agreed upon and frequently observed rhetorical function. Rhetoricians are repeatedly “sighting the public” and its discontents.8 Pictures, images, and bodily presentation, we understand, are crucial to identification and circumference drawing. While Kenneth Burke’s original formulation of identification, “You persuade a man only insofar as you can talk his language by speech, gesture, tonality, order, image, attitude, idea, identifying your ways with his,” recenters identification on words (“talk his language”), the underlying action of identification in Burke’s formula leans heavily on visual means (gesture, order, image, attitude).9 As rhetoricians of all stripes have increasingly turned to the ambient character of the rhetorical, the epideictic function has grown in prominence and importance, making it ripe for reevaluation.
