I am a PhD-Candidate at Charles University, First Faculty of Medicine, Institute for History of Medicine and Foreign Languages in Prague, Czechia.

I examine the ritual dynamics within the Christianisation of temple sleep in Late Antiquity through the lens of Ritual Studies. Ritual Studies is a inter- and multidisciplinary platform, developed by prof. dr. Ronald Grimes in the 1980s. It examines ritual from all academic disciplines, looking at theory and practice. One common feature is that rituals are not static phenomena, but are always changing and developing.

In my research, I apply the ritual theory of ecological anthropologist Roy Rappaport (1926-1997) concerning change and continuity, namely adaptation. This concept consists out of homeostasis, self-regularity and flexibility. Based on the critique of Paul Cassell, I have developed a model of ritual dynamics, focusing on homeostasis.
