It argues that for most of its history, the fourth canon was an art by which words and knowledge were remediated into visual, spatial forms, either in the mind or on the page. And it was this technique of visualization, I argue, that linked the canons of memory and invention throughout history. In contemporary rhetorical theory, however, memory palaces and mnemonic imagery have been replaced with a conception of memory grounded in psychology and critique. I argue that this move away from memory as an artificial practice has obscured the classical art’s visual precepts, consequently severing the ancient link between memory and invention. I suggest that contemporary rhetorical theorists should return to visualization to revitalize the fourth canon in the twenty-first century. Today, digital tools that visualize words and knowledge are ubiquitous.
