This article provides an original reappraisal of the notion of Minnemystik in the work of the 13th-century Flemish beguine Hadewijch of Antwerp (fl. 1240), with specific reference to its Trinitarian and Christological orientations. After an introduction to the nature and origins of Hadewijch’s work, relating to the discovery of four extant manuscripts (MS.A [2879–2880], MS.B [2877–2878], BS.C and the incomplete MS.D [385 II]) in Belgium in 1838, followed by an elucidation of the experience-driven epistemology of the Victorians Richard of St Victor (d. 1173) and Hugo of St Victor (1079–1141) as her key early scholastic influences, Hadewijch’s Minnemystik is distinguished from Wesenmystik, as encountered in the mystical work of her French contemporary and beguine counterpart, Marguerite Porete (1250–1310). From this discursive basis, Hadewijch’s Minnemystik is reassessed and represented as pertinently Trinitarian and Christological in orientation, and therefore as a theological (and not merely an enticing ‘mystical-sexual’) presentation from the 13th century.
