Exercices d'histoire des religions is a collection of the most important articles published by Philippe Borgeaud during his career as the professor of history of religions at the University of Geneva (Switzerland). These nineteen studies showcase the many reflections of the Swiss scholar of religion on the categories and tools used to describe and compare such evanescent concepts as “religions”, “myths” and “rituals”, and his methodology for a critical and comparative study of ancient and modern religions. Through them, readers will gain a clear understanding of the importance such an approach can wield in the contemporary discussions and dissents about religions
