This chapter introduces the principal Roman authors and texts studied in this book and examines the relationship between the artes and the society and politics of the early Roman Empire. The development of the artes can be understood in terms of the “Romanization” of specialized knowledge, whereby the scientific and technical contents of the artes were suffused with the peculiar interests and prerogatives of Roman Empire. The chapter surveys several ways in which this process of Romanization was instantiated in the artes: by the refiguring of specialized knowledge in the artes as Imperial self-knowledge; by an expansive conception of Roman imperium as fueling the growth of scientific knowledge; by the mastering and elaboration of Greek specialized knowledge; by the fashioning of an ideal, elite Roman readership for the artes; and by technocratic approaches to the artes relating disciplinary knowledge to Roman Imperial government.
