Mechthild of Magdeburg was a 13th-century German mystic and Beguine who lived in the Archbishopric of Magdeburg. Born into a noble Saxon family, she renounced her worldly status to join a Beguine community, where she eventually became a Dominican tertiary. She is most famous for her literary work, *The Flowing Light of the Godhead*, a collection of mystical visions and prayers. As the first mystic to compose such works in Low German rather than Latin, she played a significant role in establishing the vernacular as a language for sacred expression.
