This dissertation examines Galen of Pergamon's text On Anatomical Procedures (De anatomicis administrationibus) and considers its audience and purpose. The first chapter presents the audience of the text as Galen perceived it; I use Galen's explicit rhetoric about his readers to paint a picture of his ideal envisioned audience and then measure this against the concrete expectations that he conveys through the explicit and implicit prerequisites he demands of his readers. The second chapter, by contrast, makes strides towards uncovering the actual audience of the work by examining the ramifications of Galen's expectation that his readers will actively participate in the studies he describes; I study the availability of the books, tools, and animals that he expects his audience to be able to purchase, in order to understand the financial and social implications. The third chapter considers the text itself, taking into account the manner and timing of its composition, Galen's linguistic choices vis-à-vis his audience, and the details of his specific directions; I use this analysis to define the nature of the text and how the audience was expected to interact with it, thus necessarily engaging with the norms in ancient medical education and the role that books found there. The fourth and final chapter compares the text to his other anatomical writings, particularly his more descriptive and philosophically oriented treatise, De usu partium, as a final way to determine the purpose of this highly unusual work and its place both in his oeuvre and in its contemporary environment. / The Classics
