In Scandinavian mythology the giant Ymir was the first created being. Jotunheim was the home of the giants, of whom Skrymir was one. He was so enormous that on one occasion Loki, himself of the giant race, Thor, and Thialfi, being lost in a forest, found refuge in Skrymir's glove.
The legends and traditions of all nations are full of tales of giants. One of the stories which never loses its charm for children is that of Jack the Giant Killer, which is of Welsh origin.
