Authority: — A life by a contemporary.'] The famous Brunehaut had fled from the kingdom of the elder of her royal grandchildren, Theodebert of Austrasia, and had taken refuge with the younger, Thierri, king of Burgundy. She ruled the realm by the ascendancy of that strong and unscrupulous mind which for more than forty years raised her into a rival of the yet more famous Fredegunda, her rival in the number of murders which she committed. She ruled the king through his vices. Thierri had degenerated, like the rest of the race of Clovis, from the old Teutonic virtues, and plunged headlong into Roman licence. In vain his subjects had attempted to wean him from his countless mistresses by a marriage with the daughter of the Visigothic king. Neglected, mortified, persecuted by the arts of Brunehaut, the unhappy princess returned home. Desiderius, or Didier, Bishop of Vienne, came boldly forward and rebuked the incontinence of Thierri and his ill-usage of his wife. Brunehaut had no mind to see the king wakened from his lethargy and take the reins of government from her hands, and resenting the conduct of S. Desiderius, she sent three assassins to waylay him on his return and murder him. They attacked him with stones and killed him at Prissignac, in the principality of Dombes, afterwards called Saint-Didier de Chalarone.
