Mårten Eskil Winge was a Swedish artist. He was a professor at the Royal Swedish Academy of Arts. He was associated with the Düsseldorf school of painting. His art was influenced by the Norse mythology themes also found in works by Nils Blommér (1816–1853) and Carl Wahlbom (1810-1858).

Loki is a god in Norse mythology. Loki is the son of Fárbauti and Laufey, and the brother of Helblindi and Býleistr. Loki is married to Sigyn and they have two sons, Narfi or Nari and Váli. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr. In the form of a mare, Loki was impregnated by the stallion Svaðilfari and gave birth to the eight-legged horse Sleipnir.
