Rites typically labelled Mysteries allowed for some of the most emphatic pursuits of religious conviction in ancient Greece. This chapter explores Mystery cults from the viewpoint of personal religion. It starts from a discussion of the miniature Mystery cult of Lykosoura, which, according to Pausanias, speaks vividly to the dissemination of mysteria in Greece across time and space. Exploring the fascination with the ritual script, the author explains how this particular genre of cult practice invited various affordances. He unravels the embodied excitement of participating in Mysteries: the discussion of evidence from Eleusis allows for an ideal-type recreation of the experience made by initiands into the rites. The third section extends this inquiry, exploring the religious goals participants sought to realize. The Mysteries drew their religious meaning both from sensual cognition and the inaptitude of knowing, rather than a set theology. In conclusion, three areas in which the category of personal religion helps to unlock new perspectives on the Mysteries emerge: individual embodiment, group experience, and the omnipresent force of ritual that lent religious depth to both.
