Both sources show Radegund as a person so devoted to her religion that she tortured herself to show her faithfulness. However, one glaring difference between the two versions of the story is the childhood. In the first story, the author uses the second paragraph to tell us about her childhood. In the second version of the story, the author goes from his or her introduction immediately to Radegund's life as queen. Despite this difference, the childhood story was only a foreshadowing of what to expect. As a child, Radegund is described as someone wise beyond her years.
I found it interesting that there was an instance when Radegund supposedly deprived herself of food and other necessities of life without the abbess knowing. If this was the case, how come the author knows? Another thing I found interesting is the fact that in the first book she punished herself for not being the first to do things for others. It appears she is doing things for others not because she wants to, but because she wants to win a competition. This doesn't strike me as the behavior of a pious person.
