Mary, Mother of the Word, became an icon for excellent communication during the English Middle Ages. This engaging work explores the literature that established Mary as headmistress of the liberal arts and exemplar of perfected speech. Given England’s rich and extended practices of Marian piety, Georgiana Donavin focuses her research solely on English writers, from the Anglo-Saxon period through the Late Middle Ages. In the writings of John of Garland, John of Howden, Chaucer, Gower, Lydgate, Margery Kempe, and several anonymous lyricists and playwrights, Donavin illuminates Mary’s position as the great teacher of trivium studies and muse of various discourses. Scribit Mater begins with a survey of medieval English representations of the Virgin Mary as a wise and studious woman. It demonstrates how diverse authors imagined the Virgin’s holy speech to be the highest sign of her wisdom. These authors venerated Mary as a Christian Lady Rhetorica because they were taught to read and compose by studying Marian services and hymns, they heard Mary’s mellifluous speech in renderings of the Magnificat and other popular lyrics, or they saw the Virgin Birth as the purest articulation of the Word. They appropriated Mary’s rhetorical powers in many forms: in university textbooks teaching students to imitate the Virgin’s oratory, in meditations describing the Virgin’s body as a holy grammar, in short lyrics extolling the Virgin’s beautiful voice, in long narrative verse seeking the Virgin’s inspiration and illumination, and more. While Scribit Mater highlights different medieval English understandings of the Virgin’s sapient eloquence according to class, education, and gender, it demonstrates long-standing and widespread traditions acknowledging and celebrating the Mother’s verbal prowess.
