About Project

GEHIR is an interdisciplinary research initiative at Masaryk University, Brno, which applies innovative methods used in the study of the dynamics of complex systems (mathematical and computational modelling, network science) to the historiography of ancient Graeco-Roman religions.

Through focused case studies this initiative envisions an enrichment of the research into several religious domains of the ancient Mediterranean - Cults of Isis, Early Christianities, Hellenistic Judaism and Mithraism as well as a possibility for an exploration of the formalized modelling approaches in historiography and study of religions in general.

A Generative Historiography of the Ancient Mediterranean: Modelling and Simulating the Diffusion of Religious Ideas and Forms of Behaviour

The project systematically applies selected methods of formalized modelling and computational simulations to the study of the diffusion dynamics of specific religious ideas and forms of behavior. As such, the project strives to integrate a specific methodological framework into the academic study of religion. On the one hand, this framework may open up new avenues in the systematic study of specific instances of historical change, on the other, it may contribute to the study of more general questions related to the factors which influence the dynamics of cultural systems.

This project is centred around case studies which focus on selected religious traditions of the ancient Mediterranean (Isiac cults, Mithraism, Hellenistic Judaism and early Christianities), which can be, despite their historical specificity, viewed through the same theoretical-methodological optics, i.e. 

through the processes of (1) the dissemination of religious ideas and forms of behaviour at the population level, (2) taking place over long periods of time, (3) being studied on the basis of fragmentary sources, (4) being viewed from the theoretical concept of the diffusion of innovations, (5) and being subjected to the influence of specific environmental, social and cognitive factors. These case studies were selected on the basis of their similarity as well as their complementary specificities. In this sense, the project aims at the foundation of a “methodological laboratory” whose probes might facilitate the work of other researchers, as it combines historiography with methods of formalized modelling.

Within the study of historical processes formalized modelling is conceptualised as an innovative third way through which the limitations of the traditional 

inductive analysis of historical sources and deductive application of social-scientific and cognitive theories to social and historical phenomena can be overcome. Computational modelling can be viewed as a form of theoretical experimentation that allows the process of explaining religion to exceed the limits, given by the fragmentary nature of historical sources and by the impossibility of exposing socio-cultural and historical complexity to the traditional laboratory reduction.
