Critically examining the discourse of Indo-European scholarship over the past two hundred years, Aryan Idols demonstrates how the interconnected concepts of “Indo-European” and “Aryan” as ethnic categories have been shaped by, and used for, various ideologies.
Stefan Arvidsson traces the evolution of the Aryan idea through the nineteenth century—from its roots in Bible-based classifications and William Jones’s discovery of commonalities among Sanskrit, Latin, and Greek to its use by scholars in fields such as archaeology, anthropology, folklore, comparative religion, and history. Along the way, Arvidsson maps out the changing ways in which Aryans were imagined and relates such shifts to social, historical, and political processes. Considering the developments of the twentieth century, Arvidsson focuses on the adoption of Indo-European scholarship (or pseudoscholarship) by the Nazis and by Fascist Catholics.

A wide-ranging discussion of the intellectual history of the past two centuries,  Aryan Idols links the pervasive idea of the Indo-European people to major scientific, philosophical, and political developments of the times, while raising important questions about the nature of scholarship as well.

In Indo-European Sacred Space, Roger D. Woodard provides a careful examination of the sacred spaces of ancient Rome, finding them remarkably consistent with older Indo-European religious practices as described in the Vedas of ancient India. Employing and expanding on the fundamental methods of Émile Benveniste, as well as Georges Dumézil's tripartite analysis of Proto-Indo-European society, Woodard clarifies not only the spatial dynamics of the archaic Roman cult but, stemming from that, an unexpected clarification of several obscure issues in the study of Roman religion.
Looking closely at the organization of Roman religious activity, especially as regards sacrifices, festivals, and the hierarchy of priests, Woodard sheds new light on issues including the presence of the god Terminus in Jupiter's Capitoline temple, the nature of the Roman suovetaurilia, the Ambarvalia and its relationship to the rites of the Fratres Arvales, and the identification of the "Sabine" god Semo Sancus.  Perhaps most significantly, this work also presents a novel and persuasive resolution to the long standing problem of "agrarian Mars."
