Animal Style Art (ASA), an iconographic style expressed on monuments and material culture, is a geographically widespread phenomenon in north central Eurasia during the Iron Age (ca. 1,000 BCE – 100 CE). Frequently depicted elements of this style include composite animals composed of animal elements fused together to create a new mythical animal; a stylized geometric design within the animal; and an interaction of some kind (e.g., one figure attacking another, figures standing nearby, single animal). The research presented in this dissertation focuses on the possibility that ASA constitutes evidence for a pan-regional religion in north central Eurasia during the Iron Age. Systematic study of ancient texts, ethnography, archaeological remains, and a detailed stylistic analysis of the complex elements of ASA, have all contributed to this research. This analysis is an artifact-focused macro-scale (continental) study of ASA, breaking down the cultural contexts as well as the geographical and chronological distribution in which it occurs, and the elements of the style itself, analyzing patterns of occurrence and similarity throughout north central Eurasia. This has been accomplished by the creation of a database, specifically designed as a museum curation tool and as a Geographic Information System (GIS) resulting in a dataset of 4,633 catalog lots (a single object or set). These data contribute to the identification of internal patterns in the expression of this iconographic style between regions of north central Eurasia and is inferred as evidence for symbolic expression of religious belief. This claim is evaluated in a variety of ways focusing on three themes: mobility, political structure and social complexity, and religious belief. This first attempt at continental scale expression of symbolic systems directly tied to conceptual metaphors and religious belief has resulted in the preliminary identification of a religious landscape among all the regions, to varying degrees throughout the Iron Age. These findings help explain the widespread distribution of ASA in north central Eurasia during the Iron Age.

Jusqu'à présent, plusieurs études ont été consacrées au 'Ayyâri et à ses origines, mais aucune n'a visé le cœur mythique de cette chevalerie qui se nourrie du culte de Mithra. Cette thèse étudie en premier lieu la genèse de la chevalerie iranienne et ses idéaux dans un contexte mythico-religieux où la fonction de l'lzad Mithra est analysée comme celle de la grande Déesse-Mère des sociétés archaïques mèdes et scythes bien avant la réforme religieuse de Zoroastre. En deuxième lieu, puisque la femme est le pivot de tous les événements du récit, la thèse en se basant sur les fonctions et les caractéristiques d'un Mithra féminin, étudie la place et le rôle prépondérant de la femme dans le système religieux mithriaque. L'objectif consiste à dévoiler les raisons socio-religieuses pour lesquelles la femme est considérée, depuis la religion de Zoroastre, comme un être inférieur dans toutes les religions postérieures au caractère monothéiste et dans toutes les sociétés du type patriarcal. / Till today, several studies have been devoted to Ayyâri and its origins, but none of them has pointed to the cuit of Mithra who is the mythical source of this knigtit. This thesis studies, firstly, the origins of lranian chivalry and its ideals in a mythical-religious context in which the function of the lzad Mithra is analyzed as one of the greatest Mother-Goddess of archaic societies of Medes and Scythian; well before the religious reformation of Zoroaster. Secondly, forasmuch as the woman is the axis of all events in the story, this thesis analyzes the status and leading role of women in the Mithraic religious system, based on the functions and features of a female Mithra. The aim is to reveal the socio-religious reasons for which the woman isconsidered, since the religion of Zoroaster, as an inferior in all the subsequent religions with monotheistic character and in all the patriarchal societies.

Le croisement des sources écrites permet de restituer des confins parthes comprenant la Margiane, l’Arie, la Drangiane, l’Arachosie, une partie de la Bactriane et la vallée de l’Indus. La rareté et l’ambiguïté des sources avaient fait négliger les indications sur la Bactriane et envisager l’indépendance des autres régions à partir du Ier siècle de notre ère. Les récents renouvellements de la documentation, en particulier numismatique et archéologique, concernant l’Asie centrale et le nord-ouest de l’Inde, et les progrès accomplis par la critique des sources permettent aujourd’hui de reconsidérer la question. L’objectif de notre enquête consiste à explorer l’hypothèse d’une intégration politique de cet espace à l’empire parthe, occupé en partie par des populations réputées scythes et dont les pratiques monétaires sont habituellement interprétées comme le témoignage d’une indépendance politique. La reconstitution d’un corpus adéquat, la relecture critique des sources écrites et la reconsidération du matériel disponible montrent que la réinterprétation des données permet d’intégrer celles-ci de façon plus cohérente dans une synthèse d’ensemble enrichie. Cette étude, en faisant intervenir des « Sakas-Parthes » de Bactriane, des Parthes « scythisés » de Margiane et des « Indo-Sako-Parthes » dans les régions sud-orientales, veut montrer que la question de l’origine ethnique est de peu d’intérêt pour rendre compte de la culture et des pratiques politiques de groupes que leur position géographique frontalière vouait à avoir un peuplement ethniquement mêlé et à subir de puissants effets d’acculturation communs aux pays voisins et constamment renouvelés. / Intersecting written sources allows a restitution of Parthian eastern borders comprising Margiana, Aria, Drangiana, Arachosia, one part of Bactria, and the Indus Valley. The rarity and the ambiguity of sources had caused us to neglect the indications pertaining to Bactria and to envision the independence of the other regions from the 1st century of our era. The recent revival of sources -- in particular numismatic and archeological ones -- concerning central Asia and north-west India, as well as the progress accomplished by the criticism of sources allow us today to reconsider this statement. Our investigation aims at exploring the hypothesis of a political integration of these regions to the Parthian Empire, partly occupied by populations known as Scythian, whose monetary practices are usually interpreted as a mark of political independence. The reconstitution of an adequate corpus, the critical re-evaluation of the written sources, as well as the reconsideration of the available material allow us to reinterpret the data and to integrate them in a more consistent way within an overall improved synthesis. This study involves so called Bactrian 'Saka-Parthians', Margian 'scythianized Parthians' and south-oriental 'Indo-sako-Parthians'; it seeks to demonstrate that the issue of ethnical origin is of little interest to understand the cultural and political practices of these groups, which, due to their geographical position on the frontier, were doomed to have an ethnically mixed population and to undergo powerful acculturation effects which were common to neighbouring countries and which where constantly renewed.
