Many renowned for the learning and holiness developed and encouraged the devotion, among them St. Bernard (+1153), St. Bonaventure (+ 1274), the mystic St. Lutgarda (+1246), St Mathilda of Marburg (+ 1282), the sainted sisters Mathilda (+ 1299) and Gertrude (+ 1302) of the monastery of Helfta, and Ludolf of Saxony (+1380).
