Ullr, Ull, is a god of winter, snow, archery, and hunting in Nordic mythology. The meaning of a name is' Glory 'or' Magnificence '. Originally an important deity in the Germanic language circle, it gradually became forgotten over time and became an unknown deity.

In mythology, it is mentioned that Uler was the son of Sif and the stepson of Thor. He always hunted in the mountains wearing snow boots and carrying bows and arrows. He was a skilled archer among the gods, and his residence was in Ydalir because yew wood was a good material for making arrows. The shape of Nordic snow boots is like a shield, so the shield is also known as "Uller's ship", and he is also nicknamed "Shield God". The first marriage of female giant Skadi failed due to conflicting interests with Njord. Later, Skati and Niyod broke up and remarried to Uller. This time, their lives were happy because they had the same preferences. As a snow god, he will replace Odin's position when winter comes.
According to Saxo Grammaticus' "Gesta Danorum," Uller, also known as Ollerus, was a cunning wizard. When King Odinus (also known as Odin) was exiled, he replaced Odinus in Denmark for ten years. After Odinus returned to his country, Eurez was expelled and killed by the Danes in Sweden.
