Brief Bio

Sigyn appears in the books Gylfaginning and Skáldskaparmál in the Prose Edda. In Gylfaginning, Sigyn is introduced in chapter 31. There, she is introduced as being married to Loki, and that they have a son by the name of "Nari or Narfi".

Sigyn is mentioned again in Gylfaginning in chapter 50, where events are described differently than in Lokasenna. Here, the gods have captured Loki and his two sons, who are stated as Váli, described as a son of Loki only, and "Nari or Narfi", earlier described a son of Sigyn and Loki. Váli is changed into a wolf by the gods, and rips apart his brother "Nari or Narfi". 

The guts of "Nari or Narfi" are then used to tie Loki to three stones, after which the guts turn to iron, and Skaði places a snake above Loki. Sigyn places herself beside him, where she holds out a bowl to catch the dripping venom. However, when the bowl becomes full she leaves to pour out the venom. As a result, Loki is again described as shaking so violently that the planet shakes, and this process repeats until he breaks free, setting Ragnarök into motion.
