Flemish priest and mystic (born 1293)

John of Ruusbroec

John of Ruusbroec or Jan van Ruusbroec, sometimes modernized Ruysbroeck, was an Augustinian canon and one of the most important of the medieval mystics of the Low Countries. Some of his main literary works include The Kingdom of the Divine Lovers, The Twelve Beguines, The Spiritual Espousals, A Mirror of Eternal Blessedness, The Little Book of Enlightenment, and The Sparkling Stone. Some of his letters also survive, as well as several short sayings. He wrote in the Dutch vernacular, the language of the common people of the Low Countries, rather than in Latin, the language of the Catholic Church liturgy and official texts, in order to reach a wider audience.
