Vidar (also spelled Vithar), in Norse mythology, a strong, silent god who was the son of the principle god Odin, and who was destined to survive Ragnarok, the battle at the end of the world. Although not much is known about Vidar, according to the 'Prose (or Younger) Edda', he was almost equal in strength to Thor and was a source of great support to the other gods in any kind of danger. During Ragnarok, the monstrous wolf Fenrir would swallow Odin and kill him. Immediately, Vidar would come forward and step on the lower jaw of the wolf. On the foot with which he stepped on the jaw, he would wear a shoe for which the material was collected throughout time. (The shoe would be made of the pieces from the toe and heel that were cut and thrown away when people's shoes were made. For this reason, it was thought that any of the Norse people who desired to assist the Aesir should throw those pieces away.) With one hand, Vidar would kill the wolf by grasping its upper jaw and tearing apart its mouth. Then he would pierce the wolf's heart with his sword, avenging his father's death. Vidar would be one of the few gods to survive the battle, and thereafter he would dwell in the gods' holy places in a new world.
