Anastasia of Sirmium

Traditional accounts place a martyr named Anastasia as having given her life for the Christian faith at Sirmium during the Diocletian persecutions; the date 25 December 304 AD is commonly assigned in liturgical tradition. Much of the fuller narrative detail (various local claims of her being a widow or daughter of Praetextatus, pupil or companion of Saint Chrysogonus, or other episodic elements) derives from later 'Passio' hagiographical expansions and are regarded in modern summaries as largely legendary rather than securely historical. The cult developed through local memory in Sirmium, later translation of relics and ecclesiastical dedications, and incorporation into Roman and Byzantine liturgical life.

No contemporary physical description survives in the cited materials. Later iconography and church art associated with the cult portray her in conventional martyr/saintly dress appropriate to virgin or matronly martyrs in Christian art (as evidenced by church dedications and Baroque etchings connected to Sant'Anastasia al Palatino), but the supplied sources emphasize the absence of reliable eyewitness description from her lifetime. Museum materials and devotional imagery connected to votive practice (for example ex‑voto tablets in the Epilepsy Museum Kork) show later popular visualizations used by petitioners rather than an original portrait.

Sources present Anastasia's function in devotional and liturgical terms: she is venerated as an intercessor invoked for healing, exorcism, and deliverance from poisons or harmful potions — the Eastern epithet Pharmakolytria ("Deliverer from Potions") encapsulates this specialized remedial role. These capacities are described as the effects of her sanctity and intercession as remembered and practised by clergy and laity (liturgical petitions, votive offerings, and local healing devotion), not as a catalog of mechanistic powers; the literature repeatedly frames her remedying role in terms of petitionary prayer and liturgical commemoration.
