Wiborada, the patron saint of books and libraries, was formally canonized by the Pope in 1047---the first woman ever to receive this honor. In the 10th century, she chose a life of radical devotion by having herself enclosed in a cell at St. Gall, where she ultimately suffered martyrdom during a Hungarian raid in 926. This digital edition offers, in carefully edited and translated form, the two vitae written by monks of St. Gall, that have been preserved. The first was composed by the monastery dean Ekkehart I around 960--970, and the second by Herimannus around 1072--1076. Thanks to these accounts, complemented by additional sources, Wiborada stands among the best-documented women of the early Middle Ages.
