The silent and solitary god. He was a son of Odin and a giantess, and had a twin brother named Vali. He dwelled in Vidi. He was one of the strongest of the gods and can be considered a god of vengeance. At Ragnarok he will avenge his father by tearing the Fenris-wolf's jaw asunder. He is one of the Aesir who will survive the final battle.The Anglo-Saxon Wider or Wither is believed by some scholars to be the cognate of Old Norse Vídar. Wider is a son of Woden (Odin) by the giantess Gridr or Grithr (whose name may be related to Old English grid "true, sanctuary").
Snorri has little to say on Vidar in the Prose Edda. He calls him silent and says he has a strong shoe. This shoe the ancients believed was made of every discarded strip of shoe leather, and is the one he uses to pry the Fenris-Wolf's jaws apart to kill it. Snorri also says he is nearly as strong as Thor, strength he would need to kill the monster that took Tyr's hand.
Vídar's mother Gridr helped Thor in the Skaldskaparmal by supplying the weaponless God with iron gloves, a girdle, and staff.
