The contents of the book, Jeanne-Marguerite de Montmorency by Joseph Sigward, in the original French, are offered on this Web site. Jeanne-Marguerite de Montmorency (1646-1700), niece of the Prince of Condé, was destined for the life of King Louis XIV’s court, but she ran away, still a girl, giving up her family, her means of sustenance, her possessions, all to follow an eremitical life. Eventually she settled in a hermitage, where the passion of Jesus became the focus of her mysticism. The author drew on the subject’s correspondence with her spiritual director. The Web site is: http://www.chez.com/jeannemarguerite/. Brought to our attention by a U.S. friend of Hermitary.
The National Park Service (U.S.) has a couple of pages on historical hermits who lived on the remote Apostle Islands in Wisconsin, near Lake Superior. One was historically identified as William Wilson (http://www.nps.gov/apis/hermit.htm); the other was a Norwegian immigrant, John Nelson (http://www.nps.gov/apis/nelson.htm).
By way of Australian National University comes an assembly by a faculty member of Northwestern University of several interesting images of eremitism from the the 14th-century Yuan period at http://vandyck.anu.edu.au/work/teach/context/faculty-web.at.nwu.edu/art-history/fraser/b40/Eremitism_in_Yuan_Painting.html.
