Hunting, in the medieval times, was a way of life.
This is the case in more ways than one. On the one hand, hunting was an essential task for generating food for a noble household. According to Joseph and Frances Gies, authors of Life in a Medieval Castle,
The deer and other quarry supplied a substantial share of the meat for the castle table, and the forest supplemented game with nuts, berries, mushrooms, and other edibles. It also furnished the principal construction material and fuel for all classes. (p. 134)
