Ūsiņš ([uːs̪iɲʃ]) is a deity in Latvian mythology, the god of light and spring, symbol of fertility, guardian of horses and bees.
[2] In late 19th century R. Auniņš called Ūsiņš the god of light, by explaining with the sound "us", which can also be found in the word aust ('day').
If this interpretation is correct, he is therefore an astral deity connected to the morning and the evening star.
Lastly, Vladimir Toporov, in his studies concluded that Ūsiņš was an ancient and mythical deity of several nations.
[2] Folk songs expressed a visible merging process of Ūsiņš and Jurģi (Saint George).
[5] Ūsiņš Day was met with a rumble and great noisiness, which ties in with spring thunder nature.
[6] Ūsiņš of Horses, Māršaviņa of Cows, Barbiņa of Goats, Teniss of Pigs, Annīte of Sheep, Urbans of Calves, Protect my beasts From pestilence, from wolves!
30059-2 Ūsiņam slaughtered roosters With nine crests, To grow me cows bulls With nine layers.
30060 To the hill Ūsiņš rode With a stone foal; He brought leaves to trees, Green clover to the land.
