 Here Thomas of Cantimpré clearly expresses the Dominican conception of the centrality of the female presence, which "has an irreplaceable value for the success of the mission", just as stated, in the same years, by the "general master of the Order Jordan of Saxony".The hagiographic masterpiece of Thomas, as a work "much more elaborate and complete than the previous texts", is certainly the "Vita Piae Lutgardiae" (or "Vita Lutgardis").It is the life of Lutgardis of Tongres, who died in 1246 and later became the saint patron of Flanders.
