"Jack the Giant Killer" is a Cornish/British fairy tale and legends about a plucky lad who slays a number of giants during King Arthur's reign. The tale is characterised by violence, gore and blood-letting. Giants are prominent in Cornish folklore, Breton mythology and Welsh Bardic lore. Some parallels to elements and incidents in Norse mythology have been detected in the tale, and the trappings of Jack's last adventure with the giant Galigantus suggest parallels with French and Breton fairy tales such as Bluebeard. Jack's belt is similar to the belt in "The Valiant Little Tailor," and his magical sword, shoes, cap, and cloak are similar to those owned by Tom Thumb or those found in Welsh and Norse mythology.
