Proper offices in the Brussels, Passau Ratisbon, Salzburg, Frisingen, Bamberg, Eichstadt, Vienna, and other Breviaries. Her translation is celebrated on September 9th; and her canonization on March 29th. At Bamberg she is again commemorated on August 1st. Her life was written after 1190. This life forms the Breviary lessons at Bamberg on March 3rd and August 1st. Other authorities are the historians of the time.
S. Kunegund, or Cunegundes, was the daughter of Sigfried, count of Luxemburg, and Hedewig, his pious wife. She was married to S. Henry, duke of Bavaria. Her sister was married to Gerard, Count of Alsace. Her brothers were Henry, created, in 103, duke of Bavaria, when S. Henry was emperor; Frederick, count of Luxemburg on the death of his father; Dietrich, bishop of Metz; and others.
On the death of the emperor Otho III., S. Henry was elected king of the Romans, and was crowned at Mentz on June 6th, 1002. Kunegund was crowned empress at Paderborn, on August 10th, in the same year. Immediately on his coronation his cousin, the Margrave, Henry of Schwein-furt, demanded the dukedom of Bavaria, and his own brother, Bruno, made a similar claim. But the emperor refused to give it to either, and bestowed it on Henry, Count of Luxemburg, his wife's brother. The two disappointed competitors then conspired against him with Boleslas II., of Bohemia, but they were defeated by the emperor near Creusen, in 1003, and were pardoned. Adalbert, another brother of Kunegund, then expelled Megingod, archbishop of Treves [Trier in Germany], and seized on the diocese for himself, but the emperor deposed him, and restored the rightful archbishop.

In 1013, Henry and Kunegund received the imperial crown at Rome, from the pope. It was on this occasion that the pope bestowed on the emperor the golden ball, the emblem of the globe over which he was destined to rule. The imperial pair, it is said, had taken the vow of chastity, but of this there is no evidence. Kunegund's virtue, however, did not escape slander, and she voluntarily underwent the ordeal by fire, and walked unharmed over glowing ploughshares to testify her innocence.
S. Henry founded the bishopric of Bamberg, partly at the instigation of S. Kunegund, who obtained for the city such privileges, that it became a popular saying there, that Kunegund's silk threads defended Bamberg better than walls and towers. Pope Benedict VIII. visited Bamberg in 1020, for the purpose of consecrating the new establishment. Kunegund also built and endowed a Benedictine [monks following the Rule of St. Benedict] abbey for nuns, at Kaufungen, near Cassel. Before it was finished, in 1024, S. Henry died. On the anniversary of his death, in 1025, she assembled a great number of prelates to the dedication of her church at Kaufungen; and after the singing of the gospel, she offered on the altar a piece of the true cross, and then put off her imperial robes, and clothed herself with a poor habit; her hair was cut off, and the bishop put on her a veil, and a ring as a pledge of her fidelity to her heavenly Spouse. After she was consecrated to God in religion, she seemed entirely to forget that she had been empress, and behaved as the last in the house, being persuaded that she was so before God. She feared nothing more than whatever could bring to her mind the remembrance of her former dignity. She prayed and read much, worked with her hands, and took a singular pleasure in visiting and comforting the sick. Thus she passed the fifteen last years of her life, never suffering the least preference to be given her above any one in the community. Her mortifications at length reduced her to a very weak condition, and brought on her last sickness. Her monastery and the whole city of Cassel were grievously afflicted at the thought of their approaching loss; she alone appeared without concern, lying on a coarse hair-cloth, ready to give up the ghost, whilst the prayers of the dying were read by her side. Perceiving they were preparing a cloth fringed with gold to cover her corpse after her death, she ordered it to be taken away; nor could she be at rest till it was promised that she should be buried as a religious in her habit. She died on the 3rd of March, 1040. Her body was carried to Bamberg, and buried near that of her husband. The greatest part of her relics [the bodily remains of a saint, or objects they used, kept with honor] still remains in the same church. She was solemnly canonized by Innocent III. in 1200.
