The Center for Interdisciplinary Research of Ancient History of the Institute of Croatian History at the Department of History, Faculty of Humanities and Social Sciences, University of Zagreb, initiated the international scientific symposium "Contextualizing 'Oriental' Cults. New Lights on the Evidence between the Danube and the Adriatic," held in Zagreb and Ptuj from September 15 to 17, 2022. The co-organizing institutions were the University of Toulouse Jean Jaurès, the Austrian Academy of Sciences, the Cultural Heritage Research Center "Cvetan Grozdanov" of the Macedonian Academy of Sciences and Arts, the Archaeological Museum in Zagreb, and the Regional Museum Ptuj – Ormož. The aims of the symposium were to explore and discuss how "Oriental" cults manifested in the Danubian and Balkan provinces, based on epigraphic and material evidence. Attention was given to the spread and development of these cults in various contexts – historical, political, topographical, civil, economic, and military. Presentations and discussions yielded valuable new insights and conclusions. The international character of the symposium, with participants from several countries (Croatia, Slovenia, Austria, France, Belgium, Luxembourg, Germany, North Macedonia, Greece, Hungary, and Romania), enabled an exceptionally cohesive and dynamic academic and cultural exchange. Two years after the symposium, we have gathered scientific contributions from most participants. The publication is intended for both the domestic and international scientific community, as it presents the latest findings and conclusions on the so-called "Oriental" cults.
