This paper examines how contemporary visual culture differs from its traditional counterpart by incorporating new technologies of vision and an exponential proliferation of visual signage. Drawing on concepts of representation, the essay explains how signs, icons, symbols, and indexical codes function to convey meaning — often covertly — across art, marketing, and politics. Through examples including Turner's The Fighting Temeraire and Glen Baxter's Lazy K, the paper demonstrates how representations are socially constructed and historically contingent, and how audiences internalize symbolic codes without conscious awareness of their influence.
Contemporary visual culture differs from its traditional counterpart in two key respects: it is shaped by new technologies of vision, and it involves an exponential increase in the presence of visual cultural signage. This "empire of signs" has been growing continuously, shaped by political, social, and economic forces. In the twentieth century, however, it proliferated with particular intensity, influencing and persuading people in oblique and covert ways.
Visual culture was traditionally understood as artistic expression. Today, it also functions as a form of demagoguery — largely, though not exclusively, deployed for consumerist ends and harnessed for rhetorical and persuasive purposes. Marketing, for instance, is a field that uses visual culture and representation to engage consumers and persuade them to purchase advertised goods. Politics similarly uses symbols and representations for its own ends, as do many other people-centered enterprises.
To understand visual culture, it is essential to understand the concept of representation. The distinction between a sign and an object can be illustrated simply: a tree is the original object. It stands there; we can see it. It may be interpreted in various ways. Once that tree is painted or described, however, the very act of transposing it into a depiction renders it a representation. Transformed by another's imagination, the tree can come to mean many different things.
Many — if not all — of the signs used by persuasive media, including media professionals and marketers, are representations. These signs are symbols of entities in the world; they are reproduced or produced in different ways so that they carry deliberate meanings. It is through this process that communication between people occurs and that "information" is generated. Yet this process of representation operates so covertly and imperceptibly that most people remain unaware of it. We have been socialized into this exchange of sign and representation from an early age, making it difficult, if not impossible, to step outside of it and engage with it critically.
Not all representations are deceptive or sinister. Authors use representation as a technique for foreshadowing events: a "shadow," for instance, may indicate death, owing to the associations we have been conditioned to make between shadow and threat. Turner's painting The Fighting Temeraire (1838) features a blazing sunset as its background, symbolic perhaps of the ship's demise or the fury of battle. Symbols such as "shadow" and "fire" have acquired these connotations through social constructions that have converted them into representations. A shadow does not literally denote suffering, nor does fire always signify destruction — a flame can also provide warmth and light. Nonetheless, an author may use shadow to signal approaching unhappiness, and Turner used the blaze of the sunset to mirror the blaze of the ship and convey his intention. We understand the intentions of such artists because symbols have been internalized into specific meanings within our collective consciousness. In this way, symbols transform into particular ideas or conventions drawn from the world of ideas and language, and these symbols frequently shift in meaning across different societies and historical periods.
Signs therefore signify through the use of code. Sometimes the sign is obvious; other times, it must be decoded.
Two primary types of code are the iconic and the symbolic. Icons are a literal representation of an object (the referent) — a painting of a hamburger, for example, is intended to represent the actual hamburger. Symbols, by contrast, allude to something beyond themselves: Turner's sunset, a traffic sign, a national flag, or a word that points toward a meaning lying beneath the surface. Some representations — such as a can of Coca-Cola — can be both: it is simultaneously an icon of a physical product and a symbol of American consumerism.
Words are a typical example of symbolic code. On their own, they carry no inherent meaning. The word "rat," for instance, can mean different things in different cultural contexts, and its syllables, rearranged, may carry entirely different significance to those who know that information.
A third type of representation is the indexical sign — a symbol that points to the existence of something not immediately evident, such as smoke indicating that someone else may be nearby. Indexical signs also indicate a causal connection between things: footprints, for example, tell us automatically that someone has recently — or not so recently — passed through a place.
"Glen Baxter and Turner analyzed as symbolic representations"
It is in this way that contemporary visual culture, with its convoy of signage, exerts an influence on us that lies beyond ordinary perception. Whether encountered in a gallery, on a billboard, or embedded in a political campaign, visual representations carry layers of meaning constructed through social and historical processes. Understanding the mechanics of signs, icons, symbols, and indexical codes is therefore essential for anyone seeking to engage critically with the image-saturated world we inhabit.
