Saint Colette of Corbie (1381-1447) was a French reformer of the Franciscan Order and the founder of seventeen convents. Though of humble origin, she attracted the support of powerful patrons and important Church officials. The two biographies translated here were authored by Pierre de Vaux, her confessor and mentor, and Perrine de Baume, a nun who for decades was Colette's companion and confidant. Both accounts offer fascinating portraits of the saint as a pious ascetic assailed by demons and performing miracles, as well as in her role as skillful administrator and caring mother of her nuns. This is the first English translation of two biographies in Middle French of the most important female figures of the Middle Ages.
