A typological reading allows us to see that Margaret's early-medieval Latin passio, the Mombritius version upon which most later vernacular versions of her popular legend ultimately drew, is a tightly structured figural meditation on the theme of baptism and the sacraments of initiation. Examination of the prayers, the liturgically allusive gestures, and the symbolic elements of the whole narrative reveals a powerful female figure who “presides” over her own ordeal and with her prayers transforms the instruments of torture into baptisms by blood, fire, and water. This narrative's deep structure may offer further insight into Margaret's appeal as a patroness of childbirth.
