This paper explores the dynamic relationship between the spiritual community of Damanhur and its founder, Oberto Airaudi. Scholars consider Airaudi to be an example of Weberian charismatic leadership that was sui generis; the community, however, experienced an early routinisation, which granted it longevity and stability. Doctrinal and social evolution instead suggests a change in this charismatic relationship over the years, which occurred in four phases. His charisma passed from the ability to perform occult practices (occultist), to ideate a syncretic cosmology centred on Damanhur (religious), eventually allowing him to become an “inspirer from the outside” (inspirational). The last phase explains the survival and partial routinisation of the charisma after his death (post mortem). The study primarily relies on the analysis of Damanhurian writings, with a particular focus on the initial ten years. It also incorporates qualitative data from fieldwork and ethnographic material available in the scientific literature. The analysis suggests that Damanhur did not start as a charismatic community but as a social experiment. The development of Airaudi’s charisma, via a syncretic mythology based on a religious concept of memory, absorbed Damanhur’s social dimension, shaping it according to a collective spiritual endeavour aimed at reconnecting human beings with their divine inner nature.
