"Loki and Sigyn" by Mårten Eskil Winge
Though the meaning of the name is unknown, it could possibly be derived from the Indo-European root leug meaning "to break".
In North mythology, Loki is the son of the giant Farbauti and Laufey. He is a mischief-maker, trickster and shape-shifter appearing in the shape of a salmon,a seal, a mare and a fly. At first he would do numerous pranks until eventually his jokes became more and more evil.
He brought about the loss and return of Idunn and her apples of youth, without the apples of youth the gods would grow old like everyone else. He would often try to harm Thor, the god of thunder and once cut off the goddess Sif's golden hair.
The last straw was when he tricked the god Hodr into killing his brother Balder. Which was when the gods chained him to a rock until the coming of Ragnarök, the end of the world. While chained, the goddess Skadi put snake above him that would drip venom, which Loki's wife, Sigyn, would collect in a bowl, but when the bowl was full and she would need to empty it, the snakes venoms would drip onto Loki which was said to cause earthquakes.
Loki was married twice, first to the giant Angrboda, with whom he had three children; the wolf Fenrir, the world serpent Jörmungandr, an Hell. With his second wife, Sigyn, he fathered two sons, Vali and Narvi.
