A werewolf is a fictional being found in mythology and folklore. According to such stories, it is a human with the ability to change into a wolf, often by magical means or as the result of a curse. A werewolf is also known as a lycanthrope.
Many cultures in the past have mentioned myths of werewolves. In ancient Greek mythology, the concept is seen with the story of Lycaon, who was turned into a werewolf after eating human flesh. Norse mythology features the legend of Ulfhednar, warriors who were said to channel the wolf's spirit. Many modern European cultures today have stories of werewolf, such as the "loup-garou" in France and the "wilkolak" in Poland.
