Who is Ullr?
Ullr – From Wikipedia, the free encyclopedia
“Ullr is the son of the grain goddess Sif, and therefore the stepson of the thunder god Thor. Kennings establish that Ullr is an excellent archer, hunter, skater, and skier, handsome, warlike, and an especially apt deity to invoke before a duel. “Ullr’s ship” is a kenning for “shield,” which indicates that there was a tale of his traveling across the ocean on a shield, but if so, this tale has been lost. One of the poems in Poetic Edda, the Grímnismál, states that his home is called Ýdalir, “Yew Dales.” Yew wood was preferred above that of all other trees for making bows, which probably explains this association.”
