This paper explores women's mystical writing as a privileged yet understudied site of religious dissent within the ecclesiastical and political tensions that marked the pontificate of John XXII (1316-1334). Rather than approaching female mysticism solely as devotional or experiential literature, the contribution proposes to read mystical texts produced in the imperial territories as historically embedded sources that participated—implicitly yet meaningfully—in contemporary debates on authority, poverty, and ecclesial legitimacy. Focusing on the Dominican mystic Margaretha Ebner (1351), whose Revelations emerged within the reforming and politically contested environment of the monastery of Maria Medingen, the paper examines how mystical discourse could articulate positions within the wider conflict between papal authority and imperial power. Ebner's visions and prayers reveal explicit spiritual concern for Emperor Louis IV of Bavaria and reflect networks connected to the Gottesfreunde movement, suggesting that mystical experience functioned not only as theological reflection but also as a medium through which contemporary ecclesio-political tensions were interpreted and negotiated. Mystical narration thus emerges as both theological production and historical testimony, preserving traces of lay and monastic responses to papal disciplinary policies, the controversy on apostolic poverty, and the reshaping of religious authority in fourteenth-century imperial Europe.
