 Legends of the monastic orders: as represented in the fine arts: Henry, on assuming the Imperial dignity, married the beautiful and pious princess Cunegunda, daughter of Siegfried count of Luxembourg, who shares her husband's celestial as she shared his earthly crown. She is Saint Cunegunda, adored by her people while living and the subject of innumerable legends and ballads since her death. After a union of several years during which they lived together in love and harmony but by mutual consent in the strictest continence, the holy empress was suspected of infidelity to her husband and Henry though perfectly convinced of his wife's immaculate purity was somewhat affected by the malicious reports concerning her. Cunegunda herself would willingly have submitted to these accusations as a trial sent from Heaven to test her patience and humility but considering that Providence had placed her in a position of life wherein an evil example would cause much mischief and scandal, she appealed to the trial by ordeal and having walked unhurt over the burning ploughshares she was acquitted .This story of the Empress Cunegunda is as popular in German poetry and German art as the story of our Queen Emma, the mother of the Confessor, was formerly in England. Henry endeavored to make his wife amends for the indignities to which she had been exposed by treating her with more respect and tenderness than ever, but she obtained his permission to retire from the world and withdrew to the cloister. Henry died in 1024 and was interred in his Cathedral of Bamberg. Cunegunda, on his death, assumed the Benedictine habit and not only set an example of piety and charity but of industry working continually with her hands when not engaged in prayer for this most holy empress had often on her lips the words of St Paul that those who did not work had no right to eat. 2 Thess iii 8. She died in 1040 and was buried at Bamberg by the side of her husband. The influence of the monks of Bamberg which became one of the greatest of the Benedictine communities procured the canonization of their founder Henry by Eugenius III in 1152 and that of Cunegunda by Innocent III in 1200.
