Came across this today while reading Paul Lendvai’s The Hungarians (2003)
“Three chronicles report different versions, written between 970 and 1075, of an attack on the monistary of St Gallen and its surroundings (today in Switzerland). “The heathen barbarians” advanced like lightening through Bavaria and Swabia along Lake Constance, and inflicted heavy damage on the monastery, killing in the process Wiborada, an Aleman noblewoman, who had herself immured in a cell there ten years earlier. The anchoress was axed to death, and in 1047 Pope Clement II canonized her. Already that spring, she had warned the abbot of the exact time of her hostile hoards’’ incursion from the East, urging him to move the monks, the treasury and the priceless library to safety in time. Rumors recounts the Vita Sanctae Wiboradae; “nonetheless, they were taken seriously only when the barbarians with drawn swords pushed the neighborhood of Lake Constance to the brink of disaster, killing countless people and burning all the villagers and houses.” Only then was the seer heeded. Many people and irreplaceable books could still be saved, but Wiborada was unwilling to escape.
The life and death of St Wiborada (also honored as the patron saint of libraries), as well as the chronicles of the monks Ekkehart I, Ekkehart IV and Herimannus, continually fascinated later generations, inspiring writers, including poets, until the very recent past” (p.7-8; emphasis added).
