What is the setting of The Legend of the Christmas Rose by Selma Lagerlof?

The story's medieval setting is very important. During the Middle Ages, the Christian faith was extremely strong, and many believed in the possibility of miracles. When Robber Mother tells the abbot and the lay brother about the annual miracle in Göinge forest, the abbot believes her: "ever since his childhood, Abbot Hans had heard it said that on every Christmas Eve the forest was dressed in holiday glory." However, people in this time period also had particularly strong beliefs in evils like Satan.
