Litr is also listed as a dwarf in Völuspá (12).
A dwarf named Litr also appears in Áns saga bogsveigis, where he is coerced by the protagonist Án to build him a bow.
But in a stanza by Bragi Boddason quoted in Snorri's Skáldskaparmál (42) Litr is also mentioned in a kenning for Thor: "Lit's men's fight-challenger" ("Litar flotna fangboði"). Given that Thor is the enemy of giants, it is generally assumed that, in this kenning, Litr must refer to a giant. Litr is also a giant in one version of the poem about Thor by Þorbjörn dísarskáld, where the skald lists giants and giantesses killed by the god (but Litr only appears in one manuscript, the others mentioning Lútr instead).
This led John Lindow to suggest that there may have been originally only one Litr, a giant, for "it would not have been inappropriate for Thor to have killed a giant in some earlier version of the funeral of Baldr".
