Is memory the sleeping giant of the five parts of classical rhetoric? Some rhetoricians have been skeptical of the entire art of memory enterprise, denying essentially that there are any artificial means of training natural capacities for memory. But many have been believers, and there are vivid arguments asserting how memory as the fourth of those classical parts underwrites and illuminates each of the others. Memory is invention by another name, because the treasure house of previous performances is also a store of potential recombinations. In the most famous of the ancient mnemonic exercises, practitioners were asked to use a familiar architectural form—a sequence of rooms in a home they knew well, for instance—as a background and storage facility for items they wished to remember, and in the emphasis on sequencing there is a logic and practice of arrangement. (Cicero relayed an origin story for this topos about the Greek poet Simonides: during a performance at a dinner, he was called away; while he was away, the roof collapsed killing those within, mangling their bodies beyond recognition; but Simonides was able to identify the dead because he recalled where each guest had been sitting—and the inference was that visualizing figures against a ground is the secret of memorization.) When it comes to the work of symbolizing items to be set against this imagined background, moreover, we are certainly in the domain of style and trope. In the example that Pseudo-Cicero made famous (Rhet. Her., 3.20.33–34), we are asked to picture a scene in which a ram's testicles hang from the fourth finger of a man's hand. The goal of such imagining is to more securely recall facts that are relevant to a legal case we are memorizing—namely, the facts of an inheritance (Romans made purses from scrotums) and the availability of witnesses (testicle and testimony share an etymology). And, as for delivery, the deep paradox of memory is that organizing and practicing the passage of things from the present into the past is in fact one of the keys to performing in the moment: it is as if the artisan of a well-constructed and vividly-appointed memory palace is like an acrobat with every potential move memorized and at-hand equidistant as it were from the here and now of performance. There is thus a lot to say about the rhetorical dimensions of memory, and taken together the two books reviewed here, Nathan Johnson's Architects of Memory and Seth Long's Excavating the Memory Palace, make wide-ranging use of memory's rhetorical histories to make claims about contemporary mnemonic practices and possibilities. Nathan Johnson makes a pitch for the significance of the material infrastructures of memory work, and he anchors this pitch in histories of [End Page 100] the different cultures of Library Science and Information Studies after World War II in the United States. Johnson organizes his attention around two significant figures and their respective institutional contexts: Dorothy Crosland, a librarian at Georgia Tech from 1925 (and head librarian from 1953–1971), and Robert S. Taylor, who wrote the influential work The Making of a Library (1970) and who, within a year of his appointment as Dean in 1973, changed the name of the School of Library Science at Syracuse University to the School of Information Studies. Johnson does note the different trajectories that each of these individuals represents. In his narrative, Crosland represents a library sciences profession that women dominated and that was often coded as a "feminine" form of labor, and Taylor represents the rise of...
