with a spear facing a monstrous head, one of whose feet is thrust into the beast's forked tongue and on its lower jaw, while a hand is placed against its upper jaw, a scene interpreted as Víðarr fighting Fenrir. The depiction has also been theorized as a metaphor for Jesus's defeat of Satan. Theories Theories have been proposed that Víðarr's silence may derive from a ritual silence or other abstentions which often accompany acts of vengeance, as for example in Völuspá and Baldrs draumar when Váli, conceived for the sole purpose of avenging Baldr's death, abstains from washing his hands and combing his hair "until he brought Baldr's adversary to the funeral pyre". Parallels have been drawn between chapter 31 of Tacitus' 1st century CE work Germania where Tacitus describes that members of the Chatti, a Germanic tribe, may not shave or groom before having first slain an enemy. Dumézil Georges Dumézil theorized that Víðarr represents a cosmic figure from an archetype derived from the Proto-Indo-Europeans. Dumézil stated that he was aligned with both vertical space, due to his placement of his foot on the wolf's lower jaw and his hand on the wolf's upper jaw, and horizontal space, due to his wide step and strong shoe, and that, by killing the wolf, Víðarr keeps the wolf from destroying the cosmos, and the cosmos can thereafter be restored after the destruction resulting from Ragnarök. Dumézil thus conceives of Víðarr as a spatial god. Dumézil substantiates his claim with the text of the Lokasenna, in which Víðarr, trying to mediate the dispute with Loki, urges the other Aesir to "grant Loki his space" at the feasting table. Dumézil argues that this play on Víðarr's spatiality would have been understood by an audience familiar with the god, an interpretation further warranted by his reading of the Lokasenna as being in significant part a book of puns and word plays about the different Aesir. Dumézil also suggests that Víðarr's spatiality is seen in the Vishnu of the Vedic traditions, both etymologically (the Vi- root) and mythologically, citing the story of Bali and Vishnu. In this legend, Vishnu (in the form of Vamana) tricks the malevolent king Bali, who has secured dominion over the whole Earth, by making Bali promise to grant Vamana all the land he can cover in three paces. Vamana turns himself into a giant and strides across all of heaven
